3.6 Factors Affecting Panel Layout Design and Clearances
The designer of a panel layout needs to assess the requirements of a particular system and to consider
the following design factors.
3.6.1 Clearance / Adequate Space
Install devices to allow sufficient clearance to open and close the panel door.
Table 3.1 – Minimum Clearance Requirements for Panel Box and Door
Minimum Distance between base of device and
sides of cabinet
2 inches (50.80mm)
Minimum Distance between base of device and
wiring ducts
1.5 inches (38.10mm)
If more than one device installed in panel box (or on
door):
Minimum Distance between bases of each device
4 inches between bases of each device
(101.60mm)
When door is closed:
Minimum distance between device and closed door
(Be sure to allow enough depth for the OCS.)
2 inches (50.80mm)
3.6.2 Grounding
Panel box: The panel box needs to be properly connected to earth ground to provide a good
common ground reference.
Panel door: Tie a low impedance ground strap between the panel box and the panel door to
ensure that they have the same ground reference.
3.6.3 Temperature / Ventilation
Ensure that the panel layout design allows for adequate ventilation and maintains the specified
ambient temperature range. Consider the impact on the design of the panel layout if operating at
the extreme ends of the ambient temperature range. For example, if it is determined that a
cooling device is required, allow adequate space and clearances for the device in the panel box
or on the panel door.
Warning: It is important to follow the requirements of the panel manufacturer and to follow
all applicable electrical codes and standards.
Warning: Be sure to meet the ground requirements of the panel manufacturer and also meet
applicable electrical codes and standards.

MAN0964-01-EN CH.3
June 29, 2012 Page 21 of 122 #1037
3.6.4 Orientation
When panel-mounted, there are no orientation restrictions on the XL4 OCS.
3.6.5 Noise
Consider the impact on the panel layout design and clearance requirements if noise suppression
devices are needed. Be sure to maintain an adequate distance between the XL4 OCS and noisy
devices such as relays, motor starters, etc.
For details on output protection, especially when using contactors, solenoids… see MAN0962-01EN.
3.6.6 Shock and Vibration
The XL4 OCS has been designed to operate in typical industrial environments that may inflict
some shock and vibration on the unit. For applications that may inflict excessive shock and
vibration please use proper dampening techniques or relocate the XL4 OCS to a location that
minimizes shock and/or vibration.
3.6.7 Panel Layout Design and Clearance Checklist
The following list provides highlights of panel layout design factors:
____Meets the electrical code and applicable standards for proper grounding, etc.?
____Meets the panel manufacturer’s requirements for grounding, etc.?
____Is the panel box properly connected to earth ground? Is the panel door properly grounded? Has the
appropriate procedure been followed to properly ground the devices in the panel box and on the
panel door?
____Are minimum clearance requirements met? Can the panel door be easily opened and closed? Is
there adequate space between device bases as well as the sides of the panel and wiring ducts?
____Is the panel box deep enough to accommodate the XL4 OCS?
____Is there adequate ventilation? Is the ambient temperature range maintained? Are cooling or heating
devices required?
____Are noise suppression devices or isolation transformers required? Is there adequate distance
between the base of the XL4 OCS and noisy devices such as relays or motor starters? Ensure that
power and signal wires are not routed in the same conduit.
____Are there other requirements that impact the particular system, which need to be considered?

CHAPTER 4: ELECTRICAL INSTALLATION
Note: The datasheet is the first document you need to refer to for model-specific information
related to XL4 OCS models such as pin-outs, jumper settings, and other key installation
information. Visit our website to obtain datasheets, user documentation, and updates.
4.1 Grounding Definition
Ground: The term Ground is defined as a conductive connection between a circuit or piece of equipment
and the earth. Grounds are fundamentally used to protect an application from harmful interference
causing either physical damage such as by lightning or voltage transients or from circuit disruption often
caused by radio frequency interference (RFI).
4.2 Ground Specifications
Ideally, a ground resistance measurement from equipment to earth ground is 0 ohms. In reality it typically
is higher. The U.S. National Electrical Code (NEC) states the resistance to ground shall not exceed
twenty-five (25) ohms. Horner APG recommends less than fifteen (15) ohms resistance from our
equipment to ground. Resistance greater than twenty-five (25) ohms can cause undesirable or harmful
interference to the device.
4.3 How to Test for Good Ground
In order to test ground resistance, a Ground Resistance Tester must be used. A typical Ground
Resistance Meter Kit contains a meter, two or three wire leads, and two ground rods. Instructions are
supplied for either a two-point or three-point ground test.
Figure 4.1 shows a two-point ground connection test.

CHAPTER 5: SERIAL COMMUNICATIONS
5.1 Overview
All XL4 OCS models provide two serial ports, which are implemented with single 8-pin modular RJ45
connectors, and are labeled MJ1 and MJ2. The MJ1 serial port is RS-232 while the MJ2 port is RS-485.
MJ1 defaults to OCS programming by connecting it to the COM port of a PC running Cscape. In addition,
both MJ1 and MJ2 can be used for application-specific communication, using a variety of standard data
exchange protocols.
5.2 Port Descriptions
The MJ1 serial port contains a RS-232 interface with RTS/CTS handshaking.
The MJ2 serial port contains half-duplex RS-485 interface with no handshaking. The MJ2 RS-485
interface provides switchable termination and bias resistors internally.
5.3 Wiring and Dip Switches
5.4 RS-485 Termination
Proper RS-485 termination minimizes reflections and improves reliability.
The 485 serial port allows an internal RS-485 termination resistor to be placed across pins 1 and 2 by DIP
Switch Setting.
Only the two devices physically located at the endpoints of the RS-485 network should be terminated.
5.5 RS-485 Biasing
RS-485 biasing passively asserts a line-idle state when no device is actively transmitting, which is useful
for multi-drop RS-485 networking.

The 485 serial ports allow internal RS-485 bias resistors to be switched in, pulling pin 1 up to 3.3V and
pulling pin 2 down to ground. The Set Serial Ports item in the System Menu can be used to enable RS485 biasing. Also, an application graphics screen that writes to %SR164 can do the same thing. Setting
%SR164.1 enables MJ1 biasing and setting %SR164.2 enables MJ2 biasing.
If biasing is used, it should be enabled in only one of the devices attached to the RS-485 network.
5.6 Cscape Programming via Serial Port
The XL4 OCS MJ1 serial port supports CsCAN Programming Protocol. If a PC COM port is connected to
the XL4 OCS MJ1 serial port, Cscape can access the XL4 OCS for programming and monitoring.
Programming can also be done via the CAN port, USB port or Ethernet.
5.7 Ladder-Controlled Serial Communication
Using Serial Communication function blocks, both MJ1 and MJ2 support Generic, Modbus Master and
Modbus Slave Protocols. In addition, external modems can be connected and accessed using Init, Dial
and Answer Modem function blocks.
5.8 Downloadable Serial Communication Protocols
Both MJ1 and MJ2 also support downloadable protocols, such as Allen Bradley DF1, CsCAN Master, GE
Fanuc SNP and Modbus Master.
Note: Refer download section of our website for the list of latest supported protocols.

CHAPTER 6: CAN COMMUNICATIONS
Note: For additional CAN information, refer to the CAN Networks manual (MAN0799) on our website.
6.1 Overview
All XL4 OCS models provide a CAN networking port, which is implemented with a 5-pin connector. The
connector is labeled CAN1.
Figure 6.1 – CAN1 Connector
Like the MJ1 serial port, the CAN1 port can be used for XL4 OCS programming by connecting it to the
CAN port of a PC running Cscape. The CAN1 port also allows the XL4 OCS to exchange global data
with other OCS/RCS controllers and to access remote Network I/O devices (SmartStix, Smart Blocks and
Smart Rail Modules).
6.2 Port Description
The XL4 OCS CAN1 port implements the ISO 11898-2 physical layer and the CAN 2.0A data link layer
standards. Also, since the CAN1 port is powered by an internal isolated power supply, external CAN
power is not required.

June 29, 2012 Page 28 of 122 #1037
6.3 CAN1 Port Wiring
Figure 6.2 – CAN1 Port Connector
6.4 Cscape Programming via CAN
The CAN1 port supports CsCAN Programming Protocol. If a PC has a CAN interface installed (via PCI
card or USB), and the PC CAN port is connected to the XL4 OCS CAN1 port, Cscape can access the
XL4 OCS for programming and monitoring.
In addition, the XL4 OCS supports single-point-programming of all XL4 OCS and other OCS/RCS devices
that are connected to a CAN network. If the PC COM port is connected to the XL4 OCS MJ1 serial port,
the XL4 OCS can act as a pass-through gateway allowing Cscape to access all XL4 OCS and OCS/RCS
devices that are attached to the CAN network.
6.5 Ladder-Controlled CAN Communication
Using Put and Get Network Words function blocks, the NET1 port can exchange digital and analog global
data with other XL4 OCS or OCS/RCS devices (nodes) attached to the CAN network.
In addition, Put and Get Network Heartbeat function blocks allow nodes on the CAN network to regularly
announce their presence and to detect the presence (or absence) of other nodes on the network.
6.6 Using CAN for I/O Expansion (Network I/O)
Connecting Network I/O devices (SmartStix, SmartBlocks or SmartRails) to the XL4 OCS CAN1 port,
allows the XL4 OCS I/O to be economically expanded and distributed. A variety of modules are available
for this purpose.

June 29, 2012 Page 31 of 122 #1037
Figure 7.2 – Ethernet Module Configuration
4. Configure the Ethernet Module parameters as follows:
IP Address: Enter the static IP Address for the Ethernet Module being configured.
Note: IP Addresses are entered as four numbers, each ranging from 0 to 255. These four numbers
are called octets and they are always separated by decimal points.
Net Mask: Enter the Net Mask (sometimes called Subnet Mask) being used by all nodes on the local
network. Typical local networks use Class C IP Addresses, in which case the low octet (rightmost
number) is used to uniquely identify each node on the local network. In this case, the default Net
Mask value of 255.255.255.0 should be used.
Gateway: Enter the IP Address of a Gateway Server on the local network that allows for
communication outside of the local network. To prevent the Ethernet Module from communicating
outside the local network, set the Default Gateway IP Address to 0.0.0.0 (the default setting).
Status Register: Enter an OCS Register reference (such as %R100) to indicate which 16-bit OCS
register will have the Ethernet Status word written to it. Table 7.1 shows how this register value is
formatted and explains the meaning of each bit in the Status Word.

Version Register: Enter an OCS Register reference (such as %R101) to indicate which 16-bit OCS
register will have the Ethernet Firmware Version written to it. The value stored in the Version Register
is: (Ethernet Firmware Version * 100). For example, for Ethernet Firmware Version 4.30, the Version
register will contain 430.
Ethernet Module Register Usage - Standard Configuration
To perform Standard Configuration, simply leave the Enhanced Configuration checkbox unchecked.
In this case, Net Mask and Gateway cannot be assigned to OCS registers, while IP Address, Status
and Version must be assigned to OCS registers.
Note that the assigned IP Address register’s Direction can set to Read only or Read / Write.
If the register is Read only, the Default IP Address becomes the unit’s IP Address and is loaded into
the assigned register, where it can be read by the application. (Note: In this case, the low octet of the
IP Address can be replaced with the unit’s CAN Network ID, by checking the Use CAN ID for last
Octet checkbox.)
If the register is Read / Write, the application should write an IP Address to the assigned register, and
this value will then be the unit’s IP Address. (In this case, the Default IP Address is used only if
communication is lost during an I/O configuration download; otherwise the Default IP Address is
ignored.)
The system menu of the XL4 allows temporarily changing the IP address, net mask and gateway.
This is useful for initially communicating with the XL4 for commission or making changes in the field.
The Cscape configuration gets priority after a power cycle or transition to RUN.
Ethernet Module Register Usage - Enhanced Configuration
To perform Enhanced Configuration, first check the Enhanced Configuration checkbox. In this case,
IP Address, Net Mask, Gateway, Status and Version can all be optionally assigned to OCS
registers. By default, the register edit boxes are empty indicating that no registers are assigned.
As with the IP Address register (described in the Standard Configuration section above), Net Mask
and Gateway register Directions can be set to Read Only or Read / Write.
Ethernet Module Register Usage – General
Page 33
MAN0964-01-EN CH.7
June 29, 2012 Page 33 of 122 #1037
For the Status and Version registers (if configured), the Direction settings are always Read Only.
The Use CAN ID for last Octet checkbox does not affect Net Mask, Gateway, Status or Version
configuration.
Ethernet Module Protocol Configuration
The Protocol Support area contains a list of all the protocols supported by the platform being
configured. To activate a protocol, check its checkbox.
For protocols that require additional configuration, click on a listed protocol to select it and then click
the Configure Selected Protocol button. This will open a new dialog with configuration options for the
selected protocol.
For detailed information on individual protocol configuration refer latest version of ETN 300 Manual

CHAPTER 8: COMMUNICATION OPTIONS
8.1 Overview
To supplement the built-in MJ1 and MJ2 serial ports, additional communication options are available.
This is accomplished by installing a COM module internal to the XL4 OCS controller.
8.1.1
Previous OCS controllers shared a serial port with the communication options. The XL4 has a
separate serial port which allows using both MJ1, MJ2 and the communication options
simultaneously. Internal to the XL4 OCS, there is a CPU board, and up to two installed modules.
Models HE-XC100 / HEXT251C100 have no installed I/O or COM modules. All other models
have an I/O module in Slot 1 and could have a user-installed COM module in Slot 2.
This chapter briefly describes the Modem COM module options. For detailed information
regarding these modules, please refer to the individual documents provided with the modules.
Page 36
CH.8 MAN0964-01-EN
June 29, 2012 Page 36 of 122 #1037
8.2 Modem COM Module (XMC) Option
A Modem COM module can be installed to allow Cscape programming of an XL4 OCS over a dial-up
network. In addition, the application ladder program can take control of the modem for application-specific
modem communication.
The Modem COM module supports the standard AT command set and can connect to the dial-up network
at speeds up to 14.4 KBaud. Connection speed is auto-negotiated. The Modem COM module connects to
the dial-up network (phone line) via a cable with a standard RJ11 modular plug.
To enable Cscape programming via a dial-up network, the Modem COM module should first be
configured as the Default Programming Port, using the XL4 OCS System Menu. Doing this puts the
Modem COM module in auto-answer mode, so Cscape can call the XL4 OCS via a remote modem.
To program the ladder application to communicate via the Modem COM module, standard Cscape Serial
and Modem function blocks can be used.

CHAPTER 9: REMOVABLE MEDIA
9.1 Overview
All XL4 OCS models provide a Removable Media slot, labeled Memory Card, which supports standard
Micro SD Flash memory cards. Micro SD cards can be used to save and load applications, to capture
graphics screens and to log data for later retrieval.
Figure 9.1 – Removable Micro SD Memory Card Slot
9.2 Micro SD Cards
When the Micro SD card format was introduced, it was originally called TransFlash. Cards labeled either
Micro SD or TransFlash, with up to 32 GB of Flash memory, are compatible with the XL4 OCS Memory
slot (larger sizes were not tested at time of publication).
The Memory slot is equipped with a “push-in, push-out” connector and a Micro SD card can be safely
inserted into the Memory slot whether the XL4 OCS power is On or Off.
To install a Micro SD card: Align its 8-pin gold edge connector down, facing the front of the XL4
OCS unit as shown in Figure 9.2; then carefully push it all the way into the Memory slot. Ensure
that it clicks into place.
To remove the Micro SD card: Push down on the top of the card gently to release the spring.
The card pops up for removal.
Figure 9.2 – Installing Removable Memory Card
Page 38
CH.10 MAN0964-01-EN
June 29, 2012 Page 38 of 122
9.3 Micro SD File System
The Micro SD Memory slot uses the PC-compatible FAT32 File System. This means that a PC, with a
Micro SD-compatible card reader, can read files that have been written by the XL4 OCS and can write
files that can be read by the XL4 OCS.
However, the XL4 OCS does not support long filenames, but instead implements the 8.3 filename format.
This means that all file and directory names must consist of up to 8 characters, followed by an optional
dot, and an optional extension with up to 3 characters.
Directories and sub-directories can be nested up to 16 levels deep as long as each pathname string does
not exceed 147 characters.
9.4 Using the Removable Media Manager
The Removable Media Manager is an interactive XL4 OCS screen that performs the following functions:
a. Display number of total and free K bytes
b. Browse file and directory lists
c. Delete files and directories
d. Format a Micro SD card
e. Load and save application programs
f. View screen capture bitmaps
The Removable Media Manager can be accessed via the System Menu or by using Cscape to place a
Removable Media Manager object on an application graphics screen.
Figure 9.3 – Removable Media Submenu
9.5 Using Removable Media to Log Data
Using Read and Write Removable Media function blocks, an application ladder program can read and
write XL4 OCS register data in the form of comma-delimited files, with a .CSV extension. These files are
compatible with standard database and spreadsheet PC programs. In addition, an application ladder

9.6 Using Removable Media to Load and Save Applications
A special file type, with a .PGM extension, is used to store XL4 OCS application programs on Micro SD.
To load an application from Micro SD to the XL4 OCS, use the Removable Media Manager (open the
Removable Media Manager in the System Menu) to find and highlight the desired .PGM file, and then
press the Enter key.
To save an application from the XL4 to Micro SD, open the Removable Media Manager in the System
Menu and press the Save Pgm function key. The application will be saved in a file called
DEFAULT.PGM in the Micro SD root directory.
Note: Saving an application to Micro SD can only be done from the Removable Media System
Menu and is not available on a Removable Media Manager object that was placed on an
application graphics screen by Cscape.
Cscape can also save an application directly to a Micro SD card, which is plugged into the PC’s Micro SD
compatible card reader by selecting the Export to Removable Media item on the Cscape File menu.
9.7 Using Removable Media to View and Capture Screens
The XL4 OCS File System uses bitmap files with the .BMP extension or JPEG files with the .JPG
extension to store XL4 OCS graphic screen captures.
To view a captured XL4 OCS screen, use the Removable Media Manager to find and highlight the
desired .BMP or .JPG file, and then press Enter.
To capture an XL4 OCS screen, turning On the assigned Screen Capture Control Register will capture
the current XL4 OCS graphics screen and write it to the Micro SD card using the assigned Screen
Capture Filename.
Before capturing an XL4 OCS screen, Cscape must first be used to assign a Screen Capture Control
Register and Filename in the application. To do this, first open the Graphics Editor by selecting the
View / Edit Screens item on the Cscape Screens menu. Next select the Screen Capture item of the
Graphics Editor Config menu and then enter a Control Register and Filename.
9.8 Removable Media (RM) Function Blocks in Cscape
Note: For detailed information regarding RM function blocks and parameters, refer to the help file
in Cscape Software. Refer ‘USB Flash Media support for RM Functions’ for USB flash drive access
details.
The following RM functional blocks are available in Cscape Software. These function blocks will reference
- Micro SD when filename is prefixed with ‘A:’ or nothing OR
- USB A Flash Drive when filename is prefixed with ‘B:’.
a. Read RM csv
This function allows reading of a comma-separated value file from the Micro SD interface into the
controller register space.
b. Write RM csv
This function allows writing of a comma-separated value file to the Micro SD interface from the
controller register space.

c. Rename RM csv: This function allows renaming a file on the RM card. The data in the file is not
changed.
d. Delete RM csv: This function allows deleting a file on the RM card.
e. Copy RM csv: This function allows copying a file on the RM card. The data in the file is not changed.
9.9 Filenames used with the Removable Media (RM) Function Blocks
The RM function blocks support the flash with a DOS/Windows standard FAT-16 file system. All names
must be limited to the “8.3” format where the filename contains eight characters a period then a threecharacter extension.
The entire filename including any path must be less than or equal to 147 characters.
When creating filenames and directories it is sometimes desirable to include parts of the current date or
time. There are six special symbols that can be entered into a filename that are replaced by the OCS with
current time and date information.

CHAPTER 10: GENERAL I/O
Note: Each XL4 OCS unit is sent with a datasheet in the box. The datasheet is the first document you
need to refer to for model-specific information related to XL4 OCS models such as pin-outs, jumper
settings, and other key installation information. Visit our website to obtain datasheets, user
documentation, and updates.
10.1 Overview
The XL4 OCS is a compact unit that contains high density, very versatile I/O. Using the I/O properly
requires wiring to the proper terminals, configuring jumpers inside the XL4 OCS unit and configuring
Cscape properly. This section will offer some tips and suggestions to configure the I/O properly. For the
register mapping of the I/O, refer to the Index at the end of this manual for the pages referencing register
mapping.
10.2 Removing the XL4 OCS I/O Cover
Some I/O configurations require jumper settings to be changed inside the XL4 OCS unit. Examples of
these settings are setting positive or negative logic on digital inputs or setting current or voltage on analog
inputs.
Each XL4 OCS I/O jumper is set to a factory default. Refer to the data sheet for your XL4 OCS model to
find the default setting to determine if a jumper change is necessary for your application.
To remove the I/O cover of the XL4 OCS, remove the four (4) Phillips screws from the I/O back. It may
help to place the XL4 OCS unit face down on a clean work surface. Once the four screws are removed
the I/O cover can be lifted straight off.
Figure 10.1 – Removing the I/O Cover
Warning: Power, including I/O power must be removed from the unit prior to removing the
back cover. Failure to do so could result in electrocution and/or damage to equipment.

June 29, 2012 Page 42 of 122
Figure 10.3 – XL4 I/O Cover Removed (sample I/O board)
Once the back is removed the jumper selection can be changed. The jumper settings are documented on
each data sheet using a diagram such as Figure 9.4 below and a description of the jumper settings.
Figure 10.4 – Example Jumper Diagram
To re-install the cover, place the I/O cover back on the unit.
Place the screw back into the hole and turn the screw slowly counter clockwise until it clicks into the
threads. This prevents the screw from being cross-threaded. Now turn the screw clock-wise until the
cover is firmly secured. Repeat this process for all four (4) screws.

10.4 Solid-State Digital Outputs
Solid-state digital outputs are generally used to activate lamps, low voltage solenoids, relays and other
low voltage and low current devices.
Note: The digital outputs used on the XL4 OCS are “sourcing” outputs. This means the output applies a
positive voltage to the output pin when turned ON. When turned off, the output applies approximately zero
volts with respect to the I/O ground.
Figure 10.5 – Typical Output Wiring
The digital outputs used in the XL4 OCS have electronic short circuit protection and current limiting.
While these electronic protections work in most applications, some application may require external
fusing on these outputs.
The digital outputs in the XL4 OCS are typically controlled via %Q bits in the register mapping. Some of
the outputs are designed for high-speed applications and can be used for PWM or frequency output
applications. Please see the data sheet and the chapter on High Speed I/O for additional information.
When the controller is stopped the operation of each output is configurable. The outputs can hold the
state they were in before the controller stopped or they can go to a predetermined state. By default digital
outputs turn off. For more information on stop state see the Index to find pages referencing Cscape
settings.
The digital outputs feature an output fault bit. %I32 will turn on if any of the outputs experience a short
circuit, over-current or the output driver overheats.
10.5 Relay Outputs
Relay outputs are designed to switch loads that typically have high voltage or current requirements or
require isolation that relays provide.
Note: The design of the XL4 OCS does not require external coil power for the relays to function. The
relays will activate anytime the XL4 OCS is powered.
There are several factors that should be considered when using relays.

Relay Life – Relays are mechanical devices that have a long but limited life. Typically, switching more
current limits the life of relays. Please check the data sheets at the end of this manual for expected relay
life.
Current / Temperature De-Rating – Products containing relays often have total current limits based on
the ambient temperature of the application. Please see the product data sheet for current / temperature
de-rating information for relays.
Fusing – External fusing is generally required to protect the relays, devices and wiring from shorts or
overloads.

Warning: To protect the module and associated wiring from load faults, use external (5 A)
fuse(s) as
shown. Fuses of lower current or fusing for the entire system need to be in place to assure
the maximum current rating of the unit is not exceeded.
Warning: Connecting high voltage to any I/O pin can cause high voltage to appear at other I/O pins.

Protection for Inductive Loads – Inductive loads can cause reverse currents when they shut off that can
shorten the life of relay contacts. Some protective measures need to be determined by an engineer.
Below you will find recommendations that will work for many applications. If you have additional
questions on protection from inductive load, consult an application engineer or HEAPG Technical
Support. Details on devices that may protect outputs can be found in MAN0962-01.
Output State on Controller Stop
When the controller is stopped the operation of each output is configurable. The outputs can hold the
state they were in before the controller stopped or they can go to a predetermined state. By default relay
outputs turn off. For more information on stop state see the Index for Cscape settings pages.
10.6 Digital Inputs
Note: Refer to the datasheet for XL4 OCS model you are using for details on jumper settings.
Note: The digital inputs on the XL4 OCS are designed for low voltage DC inputs. The inputs are
designed to support both positive and negative input modes. The mode is set by a jumper setting and a
configuration parameter in Cscape. All the inputs on the unit must be configured to the same mode.
Figure 10.7 – Positive and Negative Inputs
In positive logic mode a positive voltage applied to the input will turn the input. The internal design of this
mode is basically a resistor from the input to I/O ground. This mode is sometimes called sourcing.
In negative logic mode, connecting the input to the I/O ground or zero volts will turn the input on. The
internal design of this mode is basically a resistor from the input to the positive I/O voltage (usually 12 or
24 volts). This mode is sometime called sinking.
Some of the digital inputs may support high speed input functional such as counting or frequency
measurement.
10.7 Analog Inputs
Note: See the data sheet for the XL4 OCS model you are using for jumper settings and see the
appropriate page in this manual (see Index) for details on how to use Cscape to configure the digital
filtering.
The analog inputs on the XL4 OCS allow voltage or current measurement from a variety of devices. The
voltage or current mode is set though jumpers on the unit and settings in Cscape. Each channel can be
separately configured for voltage or current mode.

The analog inputs have a digital filter that can be used to filter electrical noise that may be unavoidable in
some installations. The downside to digital filtering is the inputs will respond more slowly to sudden
changes in the actual input.
10.8 Universal Analog Inputs
Note: See the data sheet for the XL4 OCS model you are using for jumper settings and see the
appropriate pages in this manual (see Index) for details on how to use Cscape to configure the digital
filtering.
The universal analog inputs provide a high resolution, very flexible interface for a variety of analog inputs.
These inputs include voltage, current, thermocouple, RTD and millivolt. Each channel can be configured
separately using jumpers and configuration settings in Cscape.
Like the standard analog inputs, these inputs have a digital filter that can be used to filter electrical noise
that may be unavoidable in some installations. The downside to digital filtering is the inputs will respond
more slowly to sudden changes in the actual input.
10.9 Analog Outputs
Note: Refer to the datasheet for XL4 OCS model you are using for details on jumper settings.
The analog outputs on XL4 OCS devices provide high resolution voltage or current outputs. The voltage
or current selection is controlled with jumpers and configuration settings in Cscape. Note that each
channel can be separately configured for voltage or current mode.
When the controller is stopped the operation of each output is configurable. The outputs can hold the
state they were in before the controller stopped or they can go to a predetermined value. By default
analog outputs are set to a value of zero. For more information on Stop State, refer to the appropriate
pages (see Index) for the configuration chapter for Cscape settings.

CHAPTER11: HIGH SPEED I/O (HSC / PWM)
11.1 Overview
In addition to the compliment of simple analog and digital I/O, several of the XL4 OCS I/O modules
support High Speed Counting (HSC) I/O functions and may also support Pulse Width Modulation (PWM)
Output functions (non-relay modules). The HSC functions include: internal timing, frequency, totalizing,
pulse width/period and quadrature measurement. The PWM functions include: traditional PWM (with
variable rate and duty cycle) and a stepper (limited functionality) with variable acceleration and
deceleration rates. To determine function availability, refer to the associated model’s
Specification/Installation sheet (Digital DC Input/Output sections).
This chapter describes the operation of these high level I/O functions. For configuration details of these
functions, see Cscape Configuration.
11.2 Glossary
Accumulator
Register used to accumulate or store up a sum or count of many items or events.
Clear
A special function to zero out the value in a specific register. (Not used with
Frequency or Period Measurment.)
Disable
A special function to prevent the counter from running.
Encoder
A sensor or transducer for converting rotary motion or position to a series of
electronic pulses
Frequency
Input
The number of times an electromagnetic signal repeats an identical cycle in a unit of
time, usually one second.
Latch
(strobe)
A special function that uses a digital logic circuit to store one or more bits. A latch
has a data input, a clock input and an output. When the clock input is active, data on
the input is "latched" or stored and transferred to the output register either
immediately or when the clock input goes inactive. The output retains its value until
the clock goes active again.
Marker
Input into the OCS that indicates a particular position. Typically an encoder has a
marker output that represents a specific point in the rotation.
Polarity
A Polarity pull-down box is associated with each function and indicates the manner
in which the trigger happens (e.g., High level, Low Level, Falling Edge, Rising Edge).
Preload
(load)
A special function used to trigger loading of a value into a register upon an event.
(Not used with Frequency or Period Measurement.)
Quadrature
A high speed device that expresses the phase relationship between two periodic
quantities of the same period when the phase difference between them is one fourth
of a period. A coupler in which the two output signals are 90° out of phase.
Totalizer
A counter that sums the total number of cycles applied to its input.

11.3 High Speed Counter (HSC) Functions
The XL4 supports two very high speed, configurable counters. There are four dedicated inputs that can
be configures to a number of different options. Each of the two counters can run in one of five modes.
Those modes are Totalizer, Frequency Counter, Pulse Width Measurement, Period Measurement and
Quadrature measurement. For some modes, more than one HSC input may be consumed. The
measurement values are provided to ladder in a %AI register (see mapping below).
11.3.1 Frequency
In frequency mode, the frequency of the input signal is written to the accumulator in terms of
Hertz (cycles/second). When using frequency mode, four update selections are provided which
specify the width of the sample window. Note that selecting a shorter sample window provides a
quicker measurement (faster response) but lowers the frequency accuracy (resolution) and
increases the minimum frequency measurement limit. In this mode the Disable and Latch special
functions are allowed. Please see section 11.2 for a description of these functions.
11.3.2 Totalize
In totalize mode, the accumulator is simply incremented or decremented each time the input
transitions in a specific direction.
There are five different modes the totalizer can run:
Internal – This mode ties the input to the counter to an internal 10MHz or 1MHz clock. The
special functions can be used to accurately time events.
Count Up – This increments the accumulator when the input is enabled. Note that two inputs can
be assigned. Either input can cause the counter to increment. The second input can also be
disabled.
Count Down - This decrements the accumulator when the input is enabled. Note that two inputs
can be assigned. Either input can cause the counter to decrement. The second input can also
be disabled.
Up/Down (Input 1 UP/Input 2 Down) – In this mode, input one(assigned to any of the four inputs)
increments the counter, while input 2 (also assigned to any of the 4 inputs) decrements the
counter.
Clk/Dir (Input 1 Clk, Input 2 Dir) – This mode uses input 1 as a clock signal to increment or
decrement the counter and then uses input 2 to decide the direction. Input 2 disabled increments
the counter, while input 2 enabled decrements the counter.
Note, the totalize mode enables the Disable, Latch, Preload, and Clear special functions. Please
see section 11.2 for details.
11.3.3 Pulse Width Measurement
In pulse width measurement mode, the high-speed input can measure the width of a pulse stream
in one of two modes and provides a continuous indication of the last sampled value. In this mode
the Disable and Latch special functions are allowed. Please see section 11.2 for a description of
these functions.
Page 51
MAN0964-01-EN CH.11
June 29, 2012 Page 51 of 122
Width High 1 µs Counts – In this sub-mode the accumulator value will contain the number of 1 µs
counts the pulse is high.
Width Low 1 µs Counts - In this sub-mode the accumulator value will contain the number of 1 µs counts
the pulse is low.
11.3.4 Period Measurement
In period measurement mode, the high-speed input can measure the period of a pulse stream in
one of two modes and provides a continuous indication of the last sampled value. In this mode
the Disable and Latch special functions are allowed. Please see section 11.2 for a description of
these functions.
Period Rising Edges 1 µs Counts – In this sub-mode the period of the input signal is reported in
one (1) µs units. The period measurement will start on the rising edge of the input.
Period Falling Edges 1 µs Counts – In this sub-mode the period of the input signal is reported in
one (1) µs units. The period measurement will start on the falling edge of the input.
11.2.5 Quadrature
Quadrature mode uses two HSC inputs, any of the four HSC inputs can be assigned for this
purpose.
Quadrature mode works much like the totalizer except the accumulator will automatically
increment or decrement based on the rotation phase of the two inputs. See the following
example for more details. Quadrature inputs are typically used for reporting the value of an
encoder.
Width High
Width Low
Period from Rising Edge
Period from Falling Edge
Page 52
CH.11 MAN0964-01-EN
June 29, 2012 Page 52 of 122
Two modes are available for quadrature that select whether the accumulator counts up or down
when the phase of input 1 leads input 2. Check your encoder’s documentation to determine the
output form it uses or try both modes to determine if the encoder counts up when expected.
Using the above waveforms and a HSC input configuration of “Quadrature” - “1 leads 2, count
up,” the accumulator will count up when 1 is rising and 2 is low, 1 is high and 2 is rising, 1 is
falling and 2 is high, and when 1 is low and 2 is falling. This results in 4 counts per revolution. So
in order to determine the number of cycles, the accumulator would have to be divided by 4.
Marker reset operation is configured in the special operations and can be assigned to any of the 4
high speed iputs or can be assigned to be controlled by a “Q” bit in ladder.
Note, the quadrature mode enables the Disable, Latch, Preload, Clear and Marker special
functions. Please see section 11.2 for details.
11.2.6 Register Match
All counter modes support a register match function. When the accumulator value matches the
Match 1 or Match 2 value setup in %AQ registers a high speed output with either turn on, turn off
or toggle based on settings in Cscape.

11.4 High Speed Output Functions
On units that support the PWM, two dedicated outputs are available that can be configured for one of four
modes of operation. Those modes are Normal, PWM, HSC Match and Stepper.
11.4.1 Normal
When either Q1 or Q2 is configured for Normal operation, the digital output registers %Q1 and
%Q2 drives that respective output.
11.4.2 PWM
When either Q1 or Q2 is configured for PWM, the PWM function drives that respective output.
Both PWM channels may be individually enabled and can have independent frequency and duty
cycles.
The PWMs require two parameters (%AQs) to be set for operation. These parameters may be set at
run-time.
• Duty Cycle
The Duty Cycle is a 32 bit value from 0 to 32,000 indicating the relative duty cycle of the output.
For example a value of 8000 would indicate a 25% duty cycle, a value of 16,000 would indicate a
50% duty cycle. 0 turns the output off, 32,000 turns the output on.
• Frequency
The Frequency is a 32 bit value indicating the output frequency in Hertz. One over the frequency
is the period.
At controller power-up or during a download, the PWM output is maintained at zero until
both the Frequency and the Duty cycle are loaded with non-zero values. When the
controller is placed in stop mode, the state of the PWM outputs is dependent on the PWM
State on Controller Stop configuration. This configuration allows for either hold-last-state
or specific frequency and duty cycle counts. Specifying zero for either the period or duty
causes the PWM output to remain low during stop mode.
Period
Duty Cycle
Page 55
MAN0964-01-EN CH.11
June 29, 2012 Page 55 of 122
Note for standard I/O modules (1E3, 1E4 and 1E5 models) that the nominal output driver
turn-on-time delay (to reach 50% output) is 25 microseconds. Therefore, this limitation
should be considered when determining both the minimum pulse width and the duty cycle
accuracy of the application. Special high speed output options will be available.
11.4.3 HSC Output (High Speed Counter Match)
When either Q1 or Q2 is configured for HSC Output operation, HSC1 or HSC2 turns on, off or
toggles based on a comparison between the counter accumulator and match registers. See
details above in the high speed input section.
11.4.4 Stepper Function
The XL4 supports two stepper functions, one on each high speed output.
The Stepper requires five parameters (%AQs) to be set for operation. These parameters may be
set at run-time but are ‘latched’ when the stepper is commanded to start.
Start Frequency (cycles per second)
This value sets the frequency for the first cycle during the acceleration phase and the
frequency of the last cycle during the deceleration phase. When an acceleration or
deceleration count is specified, the Start Frequency must be greater than 0 and must not
exceed the run frequency or an error is generated.
Run Frequency (cycles per second)
This value sets the frequency for the last cycle during the acceleration phase, the
consistent frequency during the run phase, and the frequency of the first cycle during the
deceleration mode. The Run Frequency must be greater than 0 and must not exceed
5000 cycles/sec. or an error is generated.
Acceleration Count
This value sets the number of cycles to occur within the acceleration phase. The
frequency of the cycles within this mode will vary linearly between the specified Start and
Run frequency. The Accel count must not equal 1 or an error is generated. Setting this
value to zero disables this phase.
Run Count
This value sets the number of cycles to occur within the run phase. The frequency of the
cycles within this mode is constant at the specified Run frequency. The Run count may
be any value. Setting this value to zero disables this phase.
Deceleration Count
This value sets the number of cycles to occur within the deceleration phase. The
frequency of the cycles within this phase will vary linearly between the specified Run and
Stop frequency. The Decel count must not equal 1 or an error is generated. Setting this
value to zero disables this phase.
The stepper provides two Boolean registers to provide stepper status
Ready/Done
A high indication on this register indicates the stepper sequence can be started (i.e. not
currently busy).

CH.11 MAN0964-01-EN
June 29, 2012 Page 56 of 122
Error
A high indication on this register indicates that one of the analog parameters specified
above is invalid or the stepper action was aborted before the operation was complete.
This register is cleared on the next start command if the error was corrected.
The stepper requires one discrete register to control the stepper action. Setting this register
starts the stepper cycle. This register must remain set to complete the entire cycle. Clearing this
register before the cycle is complete aborts the step sequence and sets the error bit.
Note that setting the PLC mode to Stop while the stepper is in operation causes the
stepper output to immediately drop to zero and the current stepper count to be lost.
Note that stepper output level may cause damage or be incompatible with some motor
driver inputs. Consult drive documentation to determine if output level and type is
compatible.

locations do not appear to correspond with responding objects on the display, field adjustment is
available. To access the field adjustable touch screen calibration dialog, press and hold both the SYS
and F1 key for longer than 2 seconds and a dialog similar to figure 9.2 should appear. Thereafter, use a
plastic tip stylus and follow the dialog instructions.
Note that special system keys may be locked out from user access. If the SYS-F1 combination
does NOT respond, verify that the system menu’s Set Fkeys sub-menu’s parameter SYS_Fn is
enabled.

CHAPTER 13: USER INTERFACE
13.1 Overview
This chapter presents the user interface (or operator view) of the XL4 and some of the model specific
characteristics of the XL4 as compared to the rest of the OCS line. This chapter does NOT cover building
screens or using the CSCAPE graphics editor. For instructions on creating screens and using the
graphics editor, refer to the graphics editor help file.
The following aspects are discussed:
• Displaying and entering data
• Alpha-numeric data entry
• Navigating around screens
• Beeper acknowledgement
• Touch (slip) sensitivity
• Alarm log dialog
• RM dialog
• Screen Saver
• Dimmer
13.2 Displaying and entering Data
Figure 13.1 – Example Screen (XL4 only)
Page 74
CH.13 MAN0964-01-EN
June 29, 2012 Page 74 of 122
Multiple objects are provided for displaying data such as virtual panel lights, push buttons, numeric value
displays, bar graphs, meters, graphs and animated bitmaps. On the XL4, these graphical objects
(through ladder manipulation of attribute bits) can change color, flash or change visibility to attract
operator attention.
On objects that accept user input, the input is provided by touching the object or alternately changing an
OCS register (i.e. Function key registers). Objects that allow input generally have a raised 3D
appearance. An exception is the binary type objects, such as buttons, which are shown in a depressed
3D appearance when in the ON state. Objects that normally accept touch input may be disabled through
program control (through ladder manipulation of an attribute bit). If an object is disabled, the object’s
representation changes to a 2D appearance.
On objects that represent non-discrete information, more action may be required beyond that of simply
touching the object. For example, the slider object requires the operator to touch and slide the control in
the direction desired. Alternately, alpha-numeric entry objects invoke a pop-up alpha-numeric keypad for
additional user input. The alpha-numeric keypad is discussed below.
Note that if the numeric entry object displays >>>>>>>, the value is too big to display in the field or is
above the maximum for an editable field. Likewise, if the numeric entry object displays <<<<<<< in a
numeric field, the value is too small to display or is below the minimum for an editable field.
13.3 Alpha-numeric keypad
To allow entry of a specific number or text, several of the input objects invoke a pop-up alpha-numeric
keypad when the object is touched. An example of the alpha-numeric keypad invoked from a numeric
input object is shown in Figure 13.2. Once invoked, the operator may touch the appropriate keys to enter
a specific value. When entering a value, the alpha-numeric keypad is in one of two modes [new-value or
edit-value].
New-value mode
Generally, when the alpha-numeric keypad is first invoked, it is placed in new-value mode. Initially, the
alpha-numeric keypad displays the current value with all the digits being highlighted. Once the first digit
is entered, the current value is erased from the display and the new digit is placed in the first location.
Thereafter, no digits are highlighted and new digits are added to the rightmost position while the other
digits are shifted left.
Edit-value mode
Edit-value mode may be entered from the initial new-value mode by pressing either the left or right arrow
key before any digit key is pressed. The result will be a single character highlighted. The user may then
either touch a key to change the digit at the selected position or the up and down arrows may be used to
add or subtract (respectively) from the selected digit. The user may then use the left or right arrow keys
to select a new position.

Figure 13.2 – Alpha-numeric Keypad and ASCII Keypad
Once the desired value is entered, pressing the Enter key moves that value into the object (and the
corresponding OCS register) and the alpha-numeric keypad disappears. Alternately, pressing the ESC
key any time before the Enter key cancels the operation, leaves the objects current value unchanged, and
the alpha-numeric keypad disappears.
Note: Each numeric entry object has a configured minimum and maximum value. If the operator enters a
value outside of the configured range, the new value is ignored when Enter is pressed and the current
object value is NOT changed.
Since the alpha-numeric keypad services several different graphical objects, certain keys on the alphanumeric keypad may be disabled (grayed) when the keypad is invoked for certain objects. The following
describes the alpha-numeric keypad variation based on object.
Numeric Object
When editing a numeric value, the [+/-] or the [.] key are disabled (grayed) if the object is NOT configured
for floating-point value or a signed value.
Password Object
When editing a password value, the arrow keys, [+/-], and the [.] keys are disabled. Additionally,
overwrite mode is disabled. When entering digits, the pop-up keypad hides the value by displaying ‘*’
alternately for each digit.
ASCII Object
When editing an ASCII value, an ASCII keypad is displayed as shown figure 13.2. The ASCII keypad has
3 modes, numeric, symbols and alpha. In Alpha mode the Caps Lock button may be pressed to access
capitol letters. When you first enter this editor typing a character will overwite the entire old string and
start a new entry. You may press the back space arrow to delete the previous character. Pressing Enter
will save the entry, pressing ESC will cancel the edit and return the string to the previous value.
Text Table Object
When editing a Text Table Object, all the keys except the Up and Down arrow keys are grayed and
disabled. The next text selection is made by pressing either the Up or Down arrow.
Time/Date Object
Page 76
CH.13 MAN0964-01-EN
June 29, 2012 Page 76 of 122
When editing a Time/Date Table Object, all the keys except the Up, Down, Left and Right arrow keys are
grayed and disabled. The specific field (i.e. hour or minutes) is selected using the Left and Right arrows.
The value in the selected field is changed by pressing either the Up or Down arrow.
13.4 Screen Navigation
To allow the operator to change screens, a screen jump object is generally used. This object may be
visually represented as a 3-D button (responding to touch) or remain invisible and logically tied to an
OCS register. An optional system ICON may be configured for display along with the legend, which aids
in identifying the object as one that causes a screen change (shown below in figure 13.3)
Figure 13.3 – Typical Screen Jump Object (XL4)
13.5 Ladder Based Screen Navigation
Ladder logic can use several techniques to control screen navigation. Coils can be tied to %D registers
to make them screen coils. These coils have two modes, switch and alarm. If the ladder program
energizes an alarm display coil, the screen associated with this coil is displayed and overrides the normal
user screens. This is designed to show alarm conditions or to display other ladder-detected events.
When the text coil is de-energized, the previous screen that was being viewed before the alarm is
returned.
The switch display coil switches to the associated screen when it is energized. Once it is de-energized
the screen remains until it is switched by the user or ladder.
Screen jumps can also be triggered on other keys or based on control logic for more advanced
applications. To allow the operator to change screens, a screen jump object is generally used. This
object may be visually represented as a button (responding to touch) or remain invisible and logically
tied to an OCS register. An optional system ICON may be configured for display along with the legend,
which aids in identifying the object as one that causes a screen change.
Page 77
MAN0964-01-EN CH.13
June 29, 2012 Page 77 of 122
Figure 13.4 – Force and Switch Coils in Ladder Programming
There is also a system register that can be used to for control based screen navigation. %SR1 can be
read to determine the current screen or written to change the current screen.
Refer to the on-line help in Cscape for more information on control-based screen navigation.
13.6 Beeper Acknowledgement
The XL4 contains an internal beeper that provides an audible acknowledgment when an operator touches
a graphic object that accepts touch input. When the graphic object is enabled, a short 5ms tone is
emitted. When the graphic object is disabled, a longer 100ms tone is emitted to enounce that graphical
object is not currently accepting the touch input.
If beep acknowledgement is not desired, the beeper function can be disabled from the system menu.
13.7 Touch (Slip) Sensitivity
Touch slip sensitivity is preset to meet most applications; however, adjustment is available to reduce the
sensitivity for touch release. That is, once a graphical object (button) is touched and held by a finger, the
default touch slip sensitivity allows for a slight slip of the finger on the graphical object before the XL4
assumes touch been released (equates to approximately a quarter inch of movement with a stylus).
In some applications (such as jog buttons) where the operator is pushing a button for a period of time, the
amount of slip while holding a button pressed may exceed the default sensitivity. To increase the amount
of tolerable slip and prevent false releases of the button, the XL4 allows adjustment of the allowable slide
up to 5x the default value.
To enable the touch (slip) sensitivity, first an OCS data register must be allocated through the Graphics
editor Configuration menu for Display Settings. Once a Touch Sensitivity register is assigned, that
register may be modified [range = 1(Low) to 5 (High)] to the desired slide amount. If a value outside the
valid range is entered in the touch sensitivity register, it is ignored and the last valid value is used.
13.8 Alarms
Alarm presentation to the operator is highly configurable and beyond the scope of this document to
describe fully. For more information refer to the graphics editor help file. This section presents a typical
configuration thereby providing an introductory description on what the operator should expect.
Page 78
CH.13 MAN0964-01-EN
June 29, 2012 Page 78 of 122
The alarm object is generally used to enunciate alarms to the operator. While the display characteristics
of this object is configurable, it is generally displayed as a button that changes colors to indicate the
highest state of the alarm(s) in the alarm group it is monitoring. The following indicates the priority of the
alarm states and the default colors associated with these states.
• Highest (Red) - Unacknowledged Alarms Exist
• - (Yellow) - Acknowledged Alarms Exist
• Lowest (Green) - No Alarms Exist
Figure 13.3 – Alarm Object
To view, acknowledge and/or clear alarms, the operator must access the alarm viewer. This is
accomplished by touching an (enabled) alarm object. When accessed, the alarm viewer is displayed as
pop-up alarm viewer dialog similar to that shown in Figure 13.6.
Figure 13.4 – Alarm Viewer
The currently selected entry is indicated by a yellow highlight which can be moved up or down by
touching the arrow buttons or by directly touching an entry. If more entries exist than can fit on the page,
a scroll bar is displayed on the right side that also indicates the current relative position.
The current state of the displayed alarm is indicated by its color and optionally by an abbreviated indicator
after the date/time stamp (ALM, ACK, RTN). The operator can acknowledge an alarm by selecting it
from the list and touching the ACK button. The operator can also clear an alarm if that function is enabled
in the alarm object. If not enabled, the Clear buttons are grayed and do not respond to touch. Once view
operations are complete, simply touch the Esc button to remove the pop-up alarm viewer.
Note that OCS registers %SR181 and %SR182 are available for ladder use, which indicate presence of
unacknowledged or acknowledged alarm (respectively). The screen designer may implement these
registers to switch screens or activate the beeper to attract the operator’s attention.

MAN0964-01-EN CH.13
June 29, 2012 Page 79 of 122
13.9 Removable Media
The removable media object is generally used to inform the operator on the current state of the
removable media device and allow access to its file structure. The removable media object is displayed
as a button that changes colors to indicate the current state of the removable media device. The
following indicates the device states and the default colors associated with these states.
• Highest (Red) - Device Error
• - (Yellow) - Device Full (threshold adjustable)
• Lowest (Green) - Device OK
Figure 13.5 – Removable Media Object
To view and perform file operations, the operator must access the removable viewer. This is
accomplished by either touching an (enabled) removable media object or through the system menu.
When accessed, the removable media viewer is displayed as pop-up removable media dialog similar to
that shown in Figure 13.8.
Note that the removable media object can be configured to open the removable media viewer at a certain
directory complete with restrictions on transversing back up the file path. This may be used to restrict
operator access to non-critical files.
Figure 13.6 – Removable media viewer
The currently selected entry is indicated by a yellow highlight which can be moved up or down by
touching the arrow buttons or by directly touching an entry. If more entries exist than can fit on the page,
a scroll bar is displayed on the right side that also indicates the current relative position.
File operations are accomplished by pressing the appropriate button at the bottom of the removable
media viewer. The configuration of the removable media object that invokes the removable media viewer
Page 80
CH.13 MAN0964-01-EN
June 29, 2012 Page 80 of 122
defines what buttons are enabled and available to the user. A button is grayed and does not respond to
touch if configured as disabled.
The (Enter) button (if enabled) performs certain operations based on the selected file’s type:
.. - change display to parent directory
<DIR> - change display to child directory
bmp, jpeg - display bitmap (if compatible format)
pgm - load application (if compatible model and version)
Alternately, the (enter) button can be configured to simply load the ASCII representation of the file path
(including the file name) to a group of OCS registers. That pathname can then be used by ladder for
opening and manipulating that file.
Once view operations are complete, simply touch the Esc button to remove the pop-up removable media
viewer.
If the removable media is used in an application, the removable media device requires changing by the
operator, and the application is attempting to write to the removable media when it is removed, the screen
designer should create objects that allow the operator to temporally halt access to the removable media.
This prevents corruption to the file system if the removable media is removed during a file write
sequence. The graphic objects should set OCS register %SR174.1 (when requesting the card be
removed) and provide an indicator based on OCS register %SR174.2 (which indicates that it is safe to
remove the removable media).
Figure 13.7 – Example application segment for safe removal of removable media
13.10 Screen Saver
The XL4 screen backlight life is typically 5 years when in continuous use. If the application does not
require interaction with the XL4 for long periods of time, the backlight life can be extended by using the
screen saver function. When enabled through the system menu, the backlight is shut off (screen goes
black) after a specified time of no touch activity on the screen. When the screen saver shuts off the
backlight, any operator touch on the screen or function keys reactivates the backlight.
Note that when the screen saver is active (backlight shut off), any initial touch activity on the screen (or
function key) to reactivate the backlight is otherwise ignored by the XL4. Any additional touch activity is
also ignored by the XL4 for approximately one second thereafter.
It is possible for the application to temporarily disable the screen saver by generating a positive transition
to %SR57.16 (coil only) at a rate faster than the screen saver timeout value. This may be desired while
waiting for alarm acknowledgement.
Page 81
MAN0964-01-EN CH.13
June 29, 2012 Page 81 of 122
13.11 Screen Brightness
The XL4 provides a feature that allows screen dimming for night operation. To enable this feature, the
application must access and control system register %SR57 (Display Backlight Brightness). Screen
brightness is continuously variable by driving %SR57 through the range of 100 (full bright) to 0 (full off). It
is left to the screen designer on if and how to present a Screen Brightness control to the user.
Note that backlight life may be shorted when screen is dimmed or screen brightness is varied on a
repetitive basis.

CHAPTER 14: REGISTERS
14.1 Register Definitions
When programming the XL4 OCS, data is stored in memory that is segmented into different types. This
memory in the controller is referred to as registers. Different groups of registers are defined as either bits
or words (16 bits). Multiple registers can usually be used to handle larger storage requirements. For
example 16 single bit registers can be used to store a Word or two 16 bit registers can be used to store a
32-bit value.
Below is a list of the type of registers found in the XL4 OCS.
%AI Analog Input
16-bit input registers used to gather analog input data such as voltages, temperatures, and speed
settings coming from an attached device.
%AQ Analog Output
16-bit output registers used to send analog information such a voltages, levels or speed settings to an
attached device.
%AIG Global Analog Input
Specially defined 16-bit input registers that come from the network.
%AQG Global Analog Output
Specially defined 16-bit output registers that go to the network.
%D Display Bit
These are digital flags used to control the displaying of screens on a unit which has the ability to display a
screen. If the bit is SET, the screen is displayed.
%I Digital Input
Single-bit input registers. Typically, an external switch is connected to the registers.
%IG Global Digital Input
Specially defined single-bit inputs that come from the network.
%K Key Bit
Single-bit flags used to give the programmer direct access to any front panel keys appearing on a unit.
%M Retentive Bit
Retentive single-bit registers.
%Q Digital Output
Single-bit output registers. Typically, these bits are connected to an actuator, indicator light or other
physical outputs.
%QG Global Digital Output
Specially defined single-bit outputs that go to the network.
%R General Purpose Register
Retentive 16-bit registers.

CHAPTER 15: CSCAPE CONFIGURATION
15.1 Overview
XL4 OCS hardware is programmed with a Windows based PC application called Cscape. This
application can be used to program, configure, monitor and debug all aspects of the XL4 OCS unit.
Please see the on-line help provided with Cscape for additional details.
15.2 Cscape Status Bar
When the XL4 OCS is connected to a PC using Cscape software a Status Bar appears at the bottom of
the screen. The Cscape Status Bar can be used to determine if communications have been established
between the XL4 OCS and the Cscape program. Components of the Cscape Status Bar are explained
below.
Ready
User: NONE
HE-XExx1-CsCAN (Model=)
Equal
Local :1 Target :2(R) [no forces]
MOD
Equal Indicator – indicates whether the current program in Cscape is equal to the program
stored in the Target Controller.
•
If Equal, the program in Cscape is the same as the program stored in the Target Controller.
•
If Not Equal, the program in Cscape is not the same as the program stored in the Target
Controller.
•
If Unknown, there may have been a change since the last time the program in Cscape was
compared to the Target Controller.
Communications Status - indicates the current status of the
“pass through” Connector.
•
Local: xx – indicates the Network ID of the OCS to which
the Cscape program is physically connected through its
serial port. It can serve as a pass through device to other
nodes on the network.
• Target: yy(R) – indicates the Network ID of the device with
which the Cscape program is exchanging data.
Note: The Local unit and Target unit can be the
same unit or they can be separate units.
The following are status indicators:
(R) – Running
(D) - Do I/o
(I) – Idle
(?) – Cscape is not communicating with the remote unit.
[no forces] – indicates no I/O has been forced.
Message Line -
The contents of
these messages
are context
sensitive. The
Message line can
be empty.
Current User -
indicates who is logged
(for security purposes).
Controller Model - Network (Model Confirmation)
•
Controller Model indicates the controller model for
which the program in Cscape is configured.
• Network indicates the type of network that the program
in Cscape expects to use (e.g., CsCAN).
•
(Model Confirmation) provides the following
indications:
•
(Model=) - the actual Target Controller matches the
configured Controller Model and Network.
•
(Model Not=) – the actual Target Controller does not
match the configured Controller Model and Network.
•
(Model ?) – there may have been a change since the
last time the Target Controller was compared to the
configured Controller Model and Network.
File Modified Indicator - indicates that the file in
the selected window has been modified but has
not been saved.

15.3 Establishing Communications
The preferred method of communicating between Cscape and an XL4 OCS is via USB port. The XL4
OCS can communicate with Cscape using USB to USB, USB to serial adapters, serial port
communications via MJ1 Port, Ethernet (with an Ethernet adapter board), onboard Ethernet Port), CAN
(CsCAN) or modems. For communications other than USB or the MJ1 port please refer to the manual
which ships with the communications adapter hardware being used for programming.
To communicate with the XL4 via USB you will need the automated driver installer located on the Horner
APG web site.
For XL4 use Cscape Ver 9.30 SP3 or newer.
Next, connect a PC’s (Personal Computer running a Windows Microsoft operating system) USB port via
USB cable to the USB mini B port on the XL4 OCS.

If communications are successful, the target indicator should show the mode of the controller Target:
yy(R) as shown in the status section above in this chapter, section Cscape Status Bar.
If the controller is not communicating you may need to set the target ID of the controller in Cscape or on
the unit. The Target ID allows directing communications to a particular unit when multiple units are
connected via a CsCAN network. Units without CsCAN network ports respond to any network ID and do
not require the ID to be configured.
To check or change the ID on the XL4 OCS, press the system menu key.
The first item in the menu is Set Networks. Pressing Enter allows you to view or modify the ID of the
unit.
To change the Target ID of Cscape use the Controller | Set Target Network ID dialog.
15.3.1 Communicating via MJ1 Serial Port
Start by configuring Cscape to use the correct communications port. This can be done using the
Tools | Options | Communication Port dialog in Cscape.
Next connect the PC’s serial port to the port labeled MJ1 on the XL4.
If communications are successful, the target indicator should show the mode of the controller
Target: yy(R) as shown in the status section above.
If the controller is not communicating you may need to set the target ID of the controller in
Cscape or on the unit. The Target ID allows directing communications to a particular unit when
multiple units are connected via a CsCAN network. Units without CsCAN network ports respond
to any network ID and do not require the ID to be configured.

To check or change the ID on the XLe/XLt, press the UP and DOWN keys on the XLe/XLt
simultaneously to enter the system menu. The first item in the menu is Set Network ID.
Pressing Enter allows you to view or modify the ID of the unit.
To change the Target ID of Cscape use the Controller | Set Target Network ID dialog.
15.3.2 Communicating via On Board Ethernet Port
From Cscape go to Controller -> I/O Configure and do auto configuration for the connected
controller, Click on Config of Ethernet & go to Module Setup.
You can temporarily set the IP address, Net Mask and Gateway of the controller from the system
menu under the Set Networks menu item. Once running or power cycled the configuration will
come from the Cscape configuration stored in the unit.
In Module configuration dialog go to IP Address field enter unused IP Address and configure
unused registers in Register field & then click OK. Screen shot for the same as follows:
Download the configuration in to Controller. Connect LAN cable to the Controller in default LAN
Port.
From Cscape go to Tools -> Editor Options -> Communication Port -> configure. Select Ethernet
and enter IP address which is configured in the file. Select mode as XL Series mode from drop
down list.
The controller should get connected to Cscape. If communications are successful, the target
indicator should show the mode of the controller Target: yy(R) as shown in the status section
above.
