3.6 Factors Affecting Panel Layout Design and Clearances
The designer of a panel layout must assess the requirements of a particular system and to
consider the following design factors. A convenient checklist is provided in Section 3.6.7.
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” (50.80mm)

If more than one device installed in panel box
(or on door):
Minimum Distance between bases of each device
4” (101.60mm) between bases of each device
When door is closed:
Minimum distance between device and closed door
(Be sure to allow enough depth for XLE/XLT.)
2” (50.80mm)
3.6.2 Grounding
Panel box: The panel box must 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.

A u g u s t 2 3 , 2 0 1 8 P a g e 21 | 158
3.6.4 Orientation
When panel-mounted, there are no orientation restrictions on the XLE/XLT. However,
the orientation shown in Figure 3.3 provides for optimum legibility of the screen and
ease of use of the keypad. When DIN Rail mounted, observe the orientation shown in
Figure 3.3
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 XLE/XLT and noisy devices such as relays, motor starters, etc.
3.6.6 Shock and Vibration
The XLE/XLT 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 XLE/XLT
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? (See Table 3.1) 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 XLE/XLT?
✓ 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 XLE/XLT 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?

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 0Ω. In reality it
typically is higher. The U.S. National Electrical Code (NEC) states the resistance to ground
shall not exceed 25Ω. Horner APG recommends less than 15Ω resistance from the equipment
to ground. Resistance greater than 25Ω 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 a three-point ground test. Figure 4.1 shows

CHAPTER 5: SERIAL COMMUNICATIONS
5.1 Overview
All XLE/XLT models provide two serial ports, which are implemented with 8-pin modular RJ45
connectors and are labeled MJ1 and MJ2. The MJ1 serial port is normally used for XLE/XLT
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 both a half-duplex RS-485 interface and an RS-232 interface with
RTS/CTS handshaking.
NOTE: MJ1 shares its serial port with the optional COM module, so when an optional Modem
COM or other module is installed and active, the MJ1 connector is inactive.
The MJ2 serial port contains both a full-duplex RS-485 interface and an RS-232 interface with
no handshaking. Both the MJ1 and MJ2 RS-485 interfaces provide switchable termination and
bias resistors internally. Also, both MJ1 and MJ2 can be set as the serial programming port.

5.4 RS-485 Termination
Proper RS-485 termination minimizes reflections and improves reliability.
Both serial ports allow an internal 121Ω RS-485 termination resistor to be placed across pins 1
and 2. This can be done by installing a jumper / switching the dip switch. Please refer to the
XLE/XLT data sheet for jumper / switch locations.
NOTE: 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.
Both serial ports allow internal 390 Ω RS-485 bias resistors to be switched in, pulling pin 1 up
to 3.3V and pin 2 down to ground. The Set Serial Ports item in the System Menu (Chapter 9)
can be used to enable RS-485 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
If a PC COM port is connected to the XLE/XLT MJ1 serial port, Cscape can access the XLE/XLT
for programming and monitoring.
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 Configuration via USB
It is possible to load the program and monitor data via the USB 2.0 slave port on XLE/XLT Rev
T and later. To load via USB configure the communications port in Cscape as follows, the unit
must be connected via the USB mini-USB port to the PC or laptop:
Select Tools → Applications Settings → Communications → USB button.
It is possible to download/upload and use the data monitoring functions once connected.
NOTE: It is advisable to use an isolated USB cable between the PC/laptop and the XLE/XLT
when third party devices are connected to the XLE/XLT to avoid damaging ground loops to
the PC/laptop and/or the XLE/XLT.

CHAPTER 6: CAN COMMUNICATIONS
NOTE: For additional CAN information, refer to the CAN Networks manual (MAN0799) on the
website, North America https://hornerautomation.com or Europe: http://www.horner-apg.com
6.1 Overview
Some XLE/XLT models (XE1xx) provide a CAN networking port, which is implemented with a 5pin connector, labeled CAN 1.
The CAN1 port allows the XLE/XLT 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).
The CAN1 port also supports pass-through communications for programming multiple OCS
controllers over the CsCAN network.
The CAN 1 port also allows the XLE/XLT to exchange global data with other OCS/RCS controllers
and to access remote Network I/O devices (SmartStix Modules).
6.2 Port Description
The XLE/XLT CAN 1 port implements the ISO 11898-2 physical layer and the CAN 2.0A data link
layer standards. Also, since the CAN 1 port is powered by an internal isolated power supply,
external CAN power is not required. The CAN1 port does not supply power to the network.

6.4 Cscape Programming via CAN
The CAN 1 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 XLE/XLT CAN 1 port, Cscape can
access the XLE/XLT for programming and monitoring.
In addition, the XLE/XLT supports single-point-programming of all XLE/XLT and other OCS/RCS
devices that are connected to a CAN network. If the PC COM port is connected to the XLE/XLT
programming port (see Chapter 5), the XLE/XLT can act as a pass-through gateway allowing
Cscape to access all XLE/XLT and OCS/RCS devices that are attached to the CAN network.
NOTE: The V+ connection is
not required on the XLE/XLT.
The XLE/XLT network port is
self-powered. Supporting
devices can require this
connection, and this pin can
be used to land the extra wire
required for those devices.

6.5 Ladder-Controlled CAN Communication
Using Put and Get Network Words function blocks, the CAN 1 port can exchange digital and
analog global data with other XLE/XLT 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, SmartMod, SmartBlock, SmartRail) to the XLE/XLT
CAN 1 port, allows the XLE/XLT I/O to be economically expanded and distributed. A variety of
XLE/XLT remote I/O modules are available for this purpose.

CHAPTER 7: DOWNLOADABLE COMMUNICATION PROTCOLS
7.1 Overview
Through loadable protocol device drivers, certain models of the OCS family can provide the
ability to exchange data with remote devices such as variable-frequency drives, PLCs, and
remote I/O devices. This feature greatly expands the OCS’s control capability with negligible
effect on the OCS’s ladder scan time.
Remote devices that communicate serially must do so under certain rules of data transfer
known as a protocol. Many device manufactures have created their own protocol for
communications with their device. For an OCS to communicate with a specific device, it must
be loaded with the corresponding serial communications protocol device driver that supports
that protocol.
A limited number of protocol device drivers are packaged with the Cscape distribution;
however, as more are developed, they will be made available as add-on packages. A device
driver is typically distributed as a Windows module, which contains the Configuration Menus,
Help Files and the Target Executable Driver Code. When updating device drivers, an install
routine loads the device driver to the Cscape directory structure and makes that driver
available to Cscape applications.
Once installed, the protocol device driver can be included as part of a Cscape application by
selecting it from a list of installed protocol device drivers and attaching it to the desired serial
port (Program > Protocol Config menu). Only one protocol device driver can be associated
with a serial port, though some OCS models support multiple protocols on a single Ethernet
port.
Once the protocol is selected for a specific port, that port must be configured to match the bit
transfer size and rate of the target device(s). This is configured under the Network Config
menu, which contains port specific information such as the basic serial port parameters (i.e.
baud rate, stop bits parity, retries, etc.). In addition to the serial port parameters, this menu
also contains the transaction scan update control configuration and any network level
protocol specific configuration.
Once the network is configured, each device on the serial communications network must be
configured. For some communications (i.e. RS232), the network can be limited to one device.
The devices are configured under the Device Config menu, which contains an arbitrary device
name, the device ID and optionally an OCS status register that contains any device fault
information.
Once each device(s) is configured, a Scan List of entries must be created which defines the
transfer of data between a local (OCS ) register(s) and a remote device register(s). These
entries are created under the Data Mapping menu, which contains an OCS register, a target
device ID, a target device register address, the number of registers to transfer, and update
type.
Page 33
MAN0878-09-EN_XLE_XLT_UserManual
A u g u s t 2 3 , 2 0 1 8 P a g e 33 | 158
Each entry can be configured for one of two types of initiating a transaction: Polled and
Triggered. Polled type entries initiate a transaction with the remote device on every
transaction scan. Triggered type entries only initiate a transaction when a corresponding local
(OCS) binary trigger register is
set
. Once a triggered type transaction completes, the protocol
device driver
resets
the local (OCS) binary register to indicate completion. See Section 7.5 for
more details on Polled and Triggered entries.
These basic types are also subdivided into Read or Write operations. For polled operations, a
Read operation only reads from a remote device. Likewise, a Read/Write operation
continuously reads from the remote device unless the target OCS register value changes from
one ladder scan to another. In this case, the new OCS value is written to the target device. For
triggered operations, only a Read or Write action is available.
When downloaded to the OCS, the Scan List is scanned sequentially to generate data
transactions with the remote device. This transaction scanning can be on a continual basis
(automatic) or controlled from ladder logic (manual) once a complex connection is
programmatically created (i.e., dialup modem). The specific transaction-scanning mode is
selected from the Network Config menu.

7.4 Device List and Device Configuration
Device List
Access the Device List (CsCAN Serial) by selecting the Device button on the Protocol Config
screen and provides a list of the configured devices on the Network. Devices must be created
and exist in this list before corresponding Scan List entries can be created for this device.
Typically, the number of entries is limited to 64 devices.
Select the Config button when adding or modifying an existing device.

7.5 Scan List
The Scan List (CsCAN Serial) dialog is accessed from the Scan List button on the Protocol
Config screen and provides a Scan List of the Data Mapping entries. To transfer data between
the OCS and remote target, a Scan List must be created that defines each transaction. Each
mapping entry (transaction) contains the source and destination registers, the number of
consecutive registers transferred, the direction of the transfer and what triggers the transfer.
Typically the number of entries is limited to 512.
NOTE: The order of the Scan List is the order in which the transactions occur. Sort functions
are provided to change the order of the list. Each entry also has an identifying index. If the
device status register is enabled and a transaction failure occurs, the status register indicates
the index number of the transaction that has failed.

7.6 Data Mapping Configuration (Scan List Entry)
Update Type
This field specifies the direction and what triggers the transfer of data between the OCS and
target device for a mapping entry.
Polled Read
On every transaction scan, a read-only target device register(s) transaction occurs.
Polled Read/Write
On every transaction scan, a read target device register transaction occurs unless a local
register value has changed. The write transaction only updates those local registers that have
changed in value. If several non-consecutive local registers (contained in a single mapping
entry) change value between transaction scans, it takes several consecutive transaction scans
to write each changed register.
When the OCS is placed in RUN mode, the initial action for this mapping type is a read target
register transaction. This transaction initializes the local (OCS) register(s) to match that of the
remote device register(s). Thereafter, any change to the corresponding OCS register(s)
triggers a write operation to the remote device.

Polled Read/Write/Init
On every transaction scan, a read target device register transaction occurs unless a local
register value has changed. The write transaction only updates those local registers that have
changed in value. If several non-consecutive local registers (contained in a single mapping
entry) change value between transaction scans, it takes several consecutive scans to write
each changed register.
When the OCS is placed in RUN mode, the initial action for this mapping type is a write target
register transaction. This transaction initializes the target device register(s) to match that of
the local (OCS) register(s). Thereafter, any change to the corresponding OCS register(s)
triggers a write operation to the remote device.
The initial write transaction does not occur until after the first logic scan of the OCS. This
allows registers to be initialized locally before Writing to the target device register(s).
Triggered Read
A read transaction is triggered by a high level on a separately designated OCS (binary) trigger
register. Once the read transaction is complete (or the device is offline), the OCS trigger
register is cleared by the OCS. This update type can be used for occasion data accesses such
as retrieving trend data.
NOTE: This operation increases the associated transaction scan time and can cause the
Update Interval Exceeded Counter to increment on a tightly adjusted update interval.
Triggered Write
A write transaction is triggered by a high level on a separately designated OCS (binary)
trigger register. Once the write transaction is complete (or the device is offline), the OCS
trigger register is cleared by OCS. This function can be used for occasion data accesses such
as sending recipe data.
NOTE: This operation increases the associated transaction scan time and can cause the
Update Interval Time Exceeded Counter to increment on a tightly adjusted update interval.

Figure 8.3 – Ethernet Module Configuration
3. 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 8.3 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 4.77,
the version register will contain 477.

Get Settings From:
“Get settings from” allows the programmer to either configure the IP Address, Net Mask, or
Gateway for two functions: Configuration or Register.
1. Configuration – The configuration for the IP Address, Net Mask, or the Gateway will be assigned
using the value in the Default Settings in this window.
2. Register – The configuration for the IP Address, Net Mask, or the Gateway will be assigned
using the values in the registers assigned.
NOTE: 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.
8.5 Ethernet Configuration – IP Parameters
For primary operation, the IP address, Net Mask, and Gateway should be set in the LAN Config
of the Cscape Hardware Configuration. There are options to get IP parameters from the LAN
Config or to get parameters from registers. It is possible to set the Ethernet IP parameters
from the OCS System Menu, but only as a temporary measure. The following points on IP
parameter configuration should be considered.
• IP Parameters in Non-Volatile RAM: The IP parameters of the Cscape LAN Config are
written to non-volatile RAM on power down. IP parameter settings made in the System
Menu are not written to non-volatile RAM. Any IP parameters settings made in the
system menu will be lost after cycling power to the unit. It will revert back to the last
downloaded Cscape LAN Config that was loaded into non-volatile RAM at power down.
• “Cscape LAN Config”/ “Get Settings from” Configuration: When ‘Get settings from’ is
set to Configuration, the IP parameters specified under ‘Default Settings’ is used after
downloading to the controller. The IP parameters are represented in System Menu /
Set Networks and can be edited. However, any edits made from System Menu / Set
Networks is not retained through a power cycle. After power cycle, the unit reverts to
the last downloaded Cscape LAN Config that was loaded into non-volatile RAM at
power down.
• “Cscape LAN Config” / “Get Settings from” Register: When ‘Get settings from’ is set to
Register, the IP parameters are retrieved from the OCS registers assigned in LAN
Config. Configured registers must be populated with the desired IP parameters.
The IP parameters are represented in System Menu / Set Networks.
The IP parameters cannot be edited from System Menu / Set Networks while the unit is
in run mode.
The IP parameters always follow the values in the registers unless the OCS unit is
placed in idle mode. Then the IP parameters can be edited in System Menu / Set
Networks. When the OCS is placed back into run mode, it reverts to the registers for IP
parameters.

8.6 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 to the latest version of the
ETN 300 Manual SUP0740 [Ethernet Supplement Manual].

CHAPTER 9 SYSTEM SETTINGS AND ADJUSTMENTS
9.1 System Menu - Overview
The XLE/XLT controller has a built-in System Menu, which lets the user view System Settings
and make adjustments. To start the System Menu, press the and keys at the same time (or
set %SR3 to 1), which will display the Main Menu, as shown in Figure 9-1 and in Figure 9-2. Then
use the and keys to select a Main Menu item and press Enter to display the item’s Sub-Menu.
NOTE: The XLE display shows up to six (6) lines of text at a time. For System Menu screens that contain
more than 6 lines of text, use the and keys to scroll the display.
NOTE: The XLT display shows up to 12 lines of text at a time. For System Menu screens that contain
more than 12 lines of text, scroll the display.
9.2 System Menu – Navigation and Editing
As mentioned above, the System Menu is started by pressing the and keys at the same time
for the XLE, or the System key on the XLT. Then, either press ESC to exit the System Menu, or
use the and keys to select an item and press Enter to display the item’s Sub-Menu.
A Sub-Menu generally shows a list of System Settings and their values. After opening a SubMenu, if any of its System Settings are editable, the first System Setting that can be edited is
highlighted. If desired, the and keys can be used to select a different System Setting to be
edited.
At this point, either press ESC to exit the Sub-Menu (returning to the Main Menu) or press Enter
to edit the highlighted System Setting. If Enter is pressed, the System Setting’s value will be
highlighted, indicating that it is ready to be modified.
When modifying a System Setting’s value, use either the arrow keys ( → ) or the numeric
keys, or the appropriate touch screen icons to select a new value.
The arrow keys are used to edit System Settings that have just a few possible values. Each time
the arrow key is pressed, a new possible value is displayed. When the desired value appears,
press the Enter key to save it; otherwise press the ESC key to cancel the edit.
The numeric keys are normally used to enter numeric System Settings. In addition, to edit a
single numeric digit, use the or → key to select the digit and then either press a numeric key
or use or to modify the digit. In any case, after entering the new desired value, press the
Enter key to save it; otherwise press the ESC key to cancel the edit.

CHAPTER 10: REMOVABLE MEDIA
10.1 Overview
All XLE/XLT models provide a Removable Media slot, labeled Memory Card, which supports
standard microSD Flash memory cards. microSD cards can be used to save and load
applications, to capture graphics screens and to log data for later retrieval.
10.2 microSD Cards
When the microSD card format was introduced in 2004, it was originally called TransFlash.
Cards labeled either microSD or TransFlash, with up to 32GB of flash memory, are compatible
with the XLE/XLT OCS Memory Card slot.
The XLE/XLT Memory slot is equipped with a “push-in, push-out” connector and a microSD card
can be safely inserted into the Memory slot when the XLE/XLT is powered On or Off.
To install a microSD card: Align its 8-pin gold edge connector down, facing the front of the
XLE/XLT unit as shown in Figure 10.1; then carefully push it all the way into the Memory Card
slot. Ensure that it clicks into place.
To remove the microSD card: Push down on the top of the card gently to release the spring.
The card pops up for removal.
Figure 10.1 – Installing Removable Memory Card
Page 65
MAN0878-09-EN_XLE_XLT_UserManual
A u g u s t 2 3 , 2 0 1 8 P a g e 65 | 158
10.3 micro SD File System
In North America, XLE/XLT prior to Rev TA supported the FAT16 file system which allows up
to 2.0 GB of flash memory, while XLE/XLT with REV TA and higher support the FAT32 file
system which allows up to 2TB of flash memory. FAT microSD cards are compatible in REV TA
units and higher. The XLEe and XLTe also support the FAT32 file system.
In Europe, the new XLE starts at Rev RA and XLT starts at Rev KA.
The microSD Memory Card slot uses the PC-compatible FAT32 File System. This means that a
PC, with a microSD-compatible card reader, can read files that have been written by the
XLE/XLT and can write files that can be read by the XLE/XLT.
The XLE/XLT 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 eight (8) characters,
followed by an optional dot, and an optional extension with up to three (3) characters.
Directories and sub-directories may be nested up to 16 levels deep as long as each pathname
string does not exceed 147 characters.
10.4 Using the Removable Media Manager
The Removable Media Manager is an interactive XLE/XLT screen that performs the following
functions:
• Display number of total and free bytes
• Browse file and directory lists
• Delete files and directories
• Format a microSD card
• Load and save application programs
• View screen capture bitmaps
The Removable Media Manager can be accessed via the System Menu (see Chapter 9) or by
using Cscape to place a Removable Media Manager object on an application graphics screen.
10.5 Using Removable Media to Log Data
Using Read and Write Removable Media function blocks, an application ladder program can
read and write XLE/XLT 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 program can use Rename and Delete Removable Media
function blocks to rename and delete files.

A u g u s t 2 3 , 2 0 1 8 P a g e 66 | 158
10.6 Using Removable Media to Load and Save Applications
A special file type, with a. PGM extension, is used to store XLE/XLT application programs on
microSD.
To load an application from microSD to the XLE/XLT, use the Removable Media Manager to find
and highlight the desired .PGM file, and then press Enter.
To save an application from the XLE to microSD, open the Removable Media Manager in the
System Menu and press the F4 function key. The application will be saved in a file called
DEFAULT.PGM in the microSD root directory.
To save an application from the XLT to Micro SD, open the Removable Media Manager in System
Menu and press the Save Pgm soft key displayed at the bottom of the XLT’s touch screen.
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 in the System Menu and is not available on a Removable Media
Manager object that was placed on an application graphics screen by
Cscape.
NOTE: Saving an application to microSD does not also save register data.
Cscape can also save an application directly to a microSD card, which is plugged into the PC’s
microSD compatible card reader by selecting the Export to Removable Media item on the
Cscape File menu.
10.7 Using Removable Media to View and Capture Screens
The XLE/XLT File System uses bitmap files with the .BMP (.bmp) extension to store XLE/XLT
graphic screen captures.
To view a captured XLE/XLT screen, use the Removable Media Manager to find and highlight
the desired .BMP file, and then press Enter.
To capture an XLE/XLT screen, turning on the assigned Screen Capture Control Register will
capture the current XLE/XLT graphics screen and write it to the microSD card using the
assigned Screen Capture Filename.
Before capturing an XLE/XLT 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.

CHAPTER 11: GENERAL I/O
NOTE: The datasheet is the first document to refer to for model-specific information related
to XLE/XLT models such as pin-outs, jumper settings, and other key installation information.
Visit the website, North America https://hornerautomation.com or Europe http://www.horner-
apg.com, to obtain datasheets, user documentation, and updates.
11.1 Overview
The XLE/XLT is a compact unit that contains high density and very versatile I/O. Using the I/O
properly requires wiring to the proper terminals, configuring jumpers inside the XLE/XLT 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 Chapter 14.
11.2 Removing the XLE/XLT Back Cover
Some I/O configurations require jumper settings to be changed inside the XLE/XLT unit.
Examples of these settings are setting positive or negative logic on digital inputs or setting
current or voltage on analog inputs.
Each XLE/XLT I/O jumper is set to a factory default. Refer to the data sheet for your XLE/XLT
model to find the default setting to determine if a jumper change is necessary for your
application.
To remove the back cover of the XLE/XLT, remove the four (4) Phillips screws from the back of
the unit. It may help to place the XLE/XLT unit face down on a clean work surface. Once the
four screws are removed the back cover can be lifted straight off.
Figure 11.1 – Removing the Back 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.
Page 72
MAN0878-09-EN_XLE_XLT_UserManual
A u g u s t 2 3 , 2 0 1 8 P a g e 72 | 158
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 11.2 below and a description of
the jumper settings.
Figure 11.2 – Example Jumper & Connector Diagram
To re-install the back cover, place the cover back on the unit. The DIN clip should be on the same
side as the power connector.
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 clockwise until the cover is firmly secured. Repeat this process for all four (4) screws. Recommended
torque is 3 - 4 in-lbs (0.34 – 0.45 Nm).

11.4 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 XLE/XLT 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 11.3 – Typical Output Wiring
The digital outputs used in the XLE/XLT 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 XLE/XLT 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 configuration
(Chapter 15) for 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.

11.5 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 XLE/XLT does not require external coil power for the relays to function.
The relays will activate anytime the XLE/XLT 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 Derating – 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 (5A)
fuse(s) as shown. Fuses of lower current or fusing for the entire system must be in
place to ensure that 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 turn off
that can shorten the life of relay contacts. Some protective measures must be determined by
an engineer. Below are some recommendations that will work for many applications. If there
are additional questions on protection from inductive load, consult an application engineer or
HEAPG Technical Support.
DC Loads – General purpose diode (IN4004) in reverse bias across the load.
AC Load – MOV (Harris V140xxx for 120V, V275xx for 220V)
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 configuration
(Chapter 15) for Cscape settings.
11.6 Digital Inputs
NOTE: See Chapter 12 for high speed I/O information and refer to the datasheet for XLE/XLT
model being used for details on jumper settings.
NOTE: The digital inputs on the XLE/XLT 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 11.5 – Positive and Negative Inputs
In positive logic mode, a positive voltage applied to the input will turn the input ‘On’. 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 24V). This mode is sometimes called sinking. Some of the digital inputs
may support high speed input functional such as counting or frequency measurement.

11.7 Analog Inputs
NOTE: See the data sheet for the XLE/XLT model being used for jumper settings and Chapter
15 for details on how to use Cscape to configure the digital filtering.
The analog inputs on the XLE/XLT 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.
11.7.1 Thermistor Option for Special Orders
NOTE: The standard unit does NOT support thermistor.
Thermistor support is a factory option for Models 2, 3, and 4 only. Model 2 can support a twochannel and four-channel thermistor. Models 3 & 4 support the two-channel thermistor only.
Please refer to the Thermistor Supplement, SUP0797, for thermistor specifications and
implementation details.
11.7.2 Common Cause of Analog Input Tranzorb Failure, Models 2, 3, 4, & 5
If a 4-20mA circuit is initially wired with loop power but without a load, the analog input could
see 24VDC. This is higher than the rating of the tranzorb.
This can be solved by not connecting loop power prior to load connection or by installing a lowcost PTC in series between the load and the analog input.

11.8 Universal Analog Inputs
NOTE: See the data sheet for the XLE/XLT model being used for jumper settings and Chapter
15 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. The
Model 6 does not require jumpers and only requires a configuration parameter 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.
The Universal Analog Inputs on the Model 6 I/O board are unique from other Horner XL series
input/output cards in that they are configurable through the module configuration instead of
having to change jumper setting in order to setup the input type.
To configure the Universal Analog input type:
1. Select Analog In to access the Analog Input Configuration menu.
2. Select any of the Analog input types from the dropdowns.

11.9 Analog Outputs
NOTE: See Chapter 12 for high-speed I/O information and refer to the datasheet for XLE/XLT
model being used for details on jumper settings. The Model 6 does not require jumpers and
only requires a configuration parameter in Cscape.
The analog outputs on XLE/XLT devices provide high-resolution voltage or current outputs.
The voltage or current selection is controlled with jumpers and configuration settings in
Cscape.
NOTE: 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, see Chapter 15 for the configuration of Cscape settings.

CHAPTER 12: HIGH SPEED I/O (HSC / PWM)
12.1 Overview
In addition to the compliment of simple analog and digital I/O, several of the XLE/XLT I/O
modules support High Speed Counting (HSC) I/O functions and may also support Pulse Width
Modulation (PWM) Output functions. The HSC functions include frequency, totalizing, pulse
width, and quadrature measurement. The PWM functions include traditional PWM (with
variable rate and duty) 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 (Chapter 15).

12.2 Glossary
Table 12.1 – Glossary of High Speed I/O Terms
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 Measurement.)
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.

12.2 High Speed Counter (HSC) Functions
On units that support the HSC, four dedicated inputs are available than can be configured for
one of four modes of operation. Those modes are Frequency, Count (totalize), Pulse width or
period (pulse) and Quadrature measurement. For some modes, more than one HSC input may
be consumed. The measurement value is provided to ladder in a %AI register (see mapping
below).
NOTE: While the high-speed input circuitry has a resolution of 1 μs, measured edge transitions
must not occur faster than 100 μs for accurate measurements. Keep in mind that pulse width
measurements utilize both the rising and falling edges of the waveform, thus the pulse width
must exist longer than 100 μs.
NOTE: The
edge
polarity selection in the mode parameter for the totalize and pulse width
functions (Digital/HSC Input Configuration) assume Positive Logic regardless of the
associated I/O board’s jumper setting for the
Digital DC inputs polarity
. If Negative logic is
configured when using these functions, the opposite edge polarity must be selected in the
mode parameter.
12.2.1 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: 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 12.2 for a description of these functions.

12.2.2 Totalize
In totalize mode, the accumulator is simply incremented or decremented each time the input
transitions in a specific direction. Totalize mode is configurable to specify the edge (rising or
falling) on which the accumulator is incremented.
The totalizer supports the following modes:
Table 12.2 – Modes supported by Totalizer
Internal
This mode ties the input to the counter to an internal 10 MHz or 1
MHz clock. The special functions can be used to accurately time
events.
Count Up
This increments the accumulator when the input is enabled.
NOTE: 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: 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 1 (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 12.2 for details.
NOTE: Counter triggers off the rising edge of the signal.

MAN0878-09-EN_XLE_XLT_UserManual
A u g u s t 2 3 , 2 0 1 8 P a g e 84 | 158
Three different options are available to reset the current count. They are:
• Configured reset value
When configuring the Totalize function, a value may be specified under the
Counts per
Rev
column. When the totalizer accumulator reaches this value - 1, the accumulator will
reset to zero on the next count. Specifying zero for this value allows the totalizer to
count through the full 32-bit range before resetting.
• Ladder control
Setting registers %Q17-20 reset HSC1-4 (respectively) with no additional configuration.
When these registers are asserted, the associated totalizer accumulator is reset and
held at zero (level sensitive).
• Direct digital input control (HSC1 and HSC2 only)
HSC3 (%I11) and HSC4 (%I12) may be configured as hardware digital reset signals for
HSC1 and HSC2 (respectively). To enable these inputs as reset signals, specify the type
as
Totalize Reset
(NOTE: The corresponding Totalize HSC must be previously
configured before this option is available). The direct digital reset controls are edge
sensitive with the edge polarity configurable.
Maximum direct digital reset latency is 100μs.
The totalize function also supports an option which compares the current accumulator value
with a supplied Preset Value (PV), which is provided through a %AQ, and drives a physical
digital output based on the that comparison.
• This option (available for HSC1 and HSC2 only) drives Q1 or Q2 output point
(respectively) once the associated totalizer accumulator reaches (or exceeds) the PV
value. To enable this function, the corresponding PWM function output (Q1 or Q2) must
be configured for
HSCx Output
.
NOTE: Q1 and Q2 are PWM function outputs that may be configured independently as one of
the following: standard digital output, PWM, HSCx or stepper output.
Preset values may be modified during run-time. A preset value of zero disables (resets) the
totalizer compare function output causing the output to remain low.

12.2.3 Pulse Width Measurement
In Pulse Width Measurement mode, the high-speed input can measure the width or period of a
pulse stream in one of four modes and provides a continuous indication of the last sampled
value.
Width High 1μs Counts – In this sub-mode the accumulator value will contain the number
of 1μs counts the pulse is high.
Width Low 1μs Counts - In this sub-mode the accumulator value will contain the number
of 1μs counts the pulse is low.

12.2.3 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 12.2 for a description of these functions.
Period Rising Edges 1μs 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 1μs 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.

12.2.4 Quadrature
Two HSC inputs are consumed for each of the two possible Quadrature counters. For example,
selecting quadrature mode for HSC 1 will use HSC inputs 1 and 2, which correspond to A and B
quadrature signals. Therefore, HSC 1 and 3 may be configured for quadrature input.
Alternately, HSC 3 may be configured to reset HSC1 (quadrature) count on a marker input
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.
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.
In order to determine the number of cycles, the accumulator would have to be divided by 4.

MAN0878-09-EN_XLE_XLT_UserManual
A u g u s t 2 3 , 2 0 1 8 P a g e 88 | 158
Three different options are available to reset (or set) the current count.
• Configured Counts per Rev value
When configuring the quadrature function, a value may be specified under the Counts
per Rev column. When rotation produces an increasing count, the quadrature
accumulator resets to zero on reaching the Counts per Rev count. Alternately, when
rotation produces a decreasing count, the quadrature accumulator is set to Counts per
Rev – 1 on the count following zero. Specifying zero for this value allows the totalizer to
count through the full 32-bit range before resetting.
For example, if your encoder outputs 1024 counts per revolution, the value of 1024 can
be entered into the configuration for Counts per rev. This will result in a counter that
produces counts in the range of 0 to 1023.
• Ladder control
Setting registers %Q17 or Q19 resets quadrature (HSC) 1 or quadrature (HSC) 3
(respectively) with no additional configuration. Setting registers %Q18 or Q20 sets
quadrature (HSC) 1 or quadrature (HSC) 3 (respectively) to Counts per Rev – 1.
• Direct digital input control (HSC3) [Marker]
When HSC input 1 and 2 are used for quadrature inputs, an additional choice of marker
input becomes available for HSC input 3. The marker input is typically part of an
encoder or motion system that signals when a cycle of motion is complete. When the
marker input is triggered, the accumulator is reset to zero or to Counts per rev - 1
based on rotation direction.
Marker reset operation is enabled when HSC3 is configured for Marker type. Once
selected, one of several modes is available for marker operation. These modes can be
sub-divided into two groups of marker operation.

MAN0878-09-EN_XLE_XLT_UserManual
A u g u s t 2 3 , 2 0 1 8 P a g e 89 | 158
Asynchronous modes ignore the quadrature inputs and reset the quadrature accumulator to
zero on the configured edge (rising, falling or both). These are the most common settings
used. When configuring, asynchronous mode selections are prefixed with the word Async
.
Asynchronous Modes
o Async, Reset on rising edge
o Async, Reset on falling edge
o Async, Reset on both edges
Synchronous modes synchronize the reset (or set) to the selected quadrature input and the
selected marker polarity. Figure 11.1 below indicates which mode to select based on the
markers timing diagram. Consult the documentation provided with your encoder to determine
the marker pulse timing.
Synchronous Modes
o High, Reset on 1 rising
o Low, Reset on 1 rising
o High, Reset on 1 falling
o Low, Reset on 1 falling
o High, Reset on 2 rising
o Low, Reset on 2 rising
o High, Reset on 2 falling
o Low, Reset on 2 falling
NOTE: The Marker input is sampled within 50μs of the associated quadrature edge. It is left to
the user to determine if this meets the time constraints of the measured drive.
NOTE: If the Marker input pulse consecutively spans more than one of the specified edges,
quadrature-decoding operation is unpredictable.

The accumulator is reset to zero on the specified edge if rotation is clockwise (as shown in
Figure 12.1 above). However, if rotation is reversed, the accumulator is alternately set to
Counts per rev
– 1 on that same physical edge. When direction is reversed, that same physical
edge is seen (by the internal decoder) as having the opposite edge polarity as shown below.

12.4 Pulse Width Modulation (PWM) 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 (count = PV) and
Stepper.
12.4.1 Normal
When either Q1 or Q2 is configured for Normal operation, the digital output registers %Q1 and
%Q2 drives that respective output.
12.4.2 PWM
When either Q1 or Q2 is configured for PWM, the PWM function drives that respective output.
Both PWM channels may be individually enabled; however, when both PWM outputs are
enabled, both share the same output frequency (with the low going pulses synchronized).
Otherwise, each PWM’s pulse width can be independently adjusted.
The PWMs require three parameters (%AQs) to be set for operation. These parameters may
be set at run-time. The register set and prescale calculation differ depending upon the
XLE/XLT hardware being used, hardware revs A-R use the following resisters and scaling:
• Prescale Count - Revision A-R or Legacy Modules
The prescale (%AQ5-6) count sets the resolution of the internal counter used for
generating the PWM output. The (prescale count + 1) is a divisor applied to a 16MHz clock
that drives the internal PWM counter. For the highest resolution PWM output, this value
should be set as low as possible (0 provides a 1/16 micro second resolution). Both the
Period and Duty cycle (pulse width) are based on
counts
of the internal PWM counter.
The frequency of the PWM output is calculated using the following formula:
Frequency =
( )
tPeriodCountescaleCoun +1Pr
000,000,16
• Pre-scale Count (Revision T and onwards or Gen2 or later)
NOTE: In Europe, the new XLE starts at Rev RA, and new XLT starts at Rev KA.
The pre-scale %AQ5 (PWM1) or %AQ6 (PWM2) count sets the resolution of the internal
counter used for generating the PWM output. The (pre-scale count + 1) is a divisor
applied to a 32MHz clock that drives the internal PWM counter. For the highest
resolution PWM output, this value should be set as low as possible (0 provides a 1/32
micro second resolution). Both the Period and Duty cycle (pulse width) are based on
counts
of the internal PWM counter.
The frequency of the PWM output is calculated using the following formula:
Frequency =
( )
tPeriodCountescaleCoun +1Pr
000,000,32
Page 93
MAN0878-09-EN_XLE_XLT_UserManual
A u g u s t 2 3 , 2 0 1 8 P a g e 93 | 158
• Period Count
This value (%AQ7-8) sets the period of the output signal by specifying the number of
internal PWM counter
counts
before the cycle is reset (larger count results in a smaller
frequency). The duration of each
count
is determined by the pre-scaler value. This
parameter affects the Period of both PWM outputs.
See the previous formula to see how the pre-scale and period counts create an output
frequency. For example, setting the PWM for 1μs resolution (pre-scale=15), and a period
count of 20,000 would result in a 50Hz output.
• Duty Cycle Count
This value (PWM1: %AQ1-2, PWM2: %AQ3-4) sets the width of the output signal by
specifying the number of internal PWM counter counts that the output is maintained
high. The duration of each count is determined by the pre-scaler value. Each PWM
channel has its own duty cycle count parameter.
Setting the period count to 1000 and the duty cycle count to 500 results in a duty cycle
of 50 percent. Changing just the duty cycle count to a value of 250 results in a duty
cycle of 25%.

At controller power-up or during a download, the PWM output is maintained at zero until
both the Period (count) and the Duty cycle (count) 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 prescale, period and duty cycle counts. Specifying zero for
either the period or duty causes the PWM output to remain low during stop mode.
NOTE: The nominal output driver turn-on-time delay (to reach 50% output) is 25μs on
Models 3-5. Therefore, this limitation should be considered when determining both the
minimum pulse width and the duty cycle accuracy of the application.
The following table shows the PWM registers used for the Legacy and Extended
PWM revisions:

1) When an old XLE/XLT file is auto configured to a new XLE/XLEe or XLT/XLTe file, then
the old formula and registers are taken and firmware will do the required adjustments
for the PWM to function normally.
2) When a new XLE/XLT file is created, then the new formula will be applied and the
configuration must be as per the new register set.

12.4.4 HSC (High Speed Counter)
When either Q1 or Q2 is configured for HSC operation, HSC1 or HSC2 totalize functions are
extended to allow respective direct output control based on a comparison of the current
count and a preset value (PV). See totalize in the HSC section above for more information.
12.4.5 Stepper Function
When Q1 is configured for Stepper, the stepper function is enabled at the Q1 output. Only one
stepper function and output is available.
NOTE: When Q1 is configured for stepper operation, Q2 operation is limited to direct digital
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 (%AQ1) 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 zero (0)
and must not exceed the run frequency or an error is generated.
Run Frequency (cycles per second)
This value (%AQ2) 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 zero (0) and
must not exceed 5000 cycles/sec. or an error is generated.
Acceleration Count
This value (%AQ3-4) 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 (0) disables this phase.
Run Count
This value (%AQ5-6) 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 (%AQ7-8) 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 (%I30) indicates the stepper sequence can be started
(i.e. not currently busy).
Error
A high indication on this register (%I31) 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 (%Q1) 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: 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: 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.

CHAPTER 13: USER INTERFACE
13.1 Overview
This chapter presents the user interface (or operator view) of the XLE/XLT and some of the
model specific characteristics of the XLE/XLT 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 in
CSCAPE.
13.2 Screen Navigation
The screen navigation on the XLE/XLT is quite flexible. Basic methods will be described here.
Control programming can be used to create complex screen navigation techniques.
One form of screen navigation is the Jump Screen graphics object. This object is typically tied
to a soft key (One of the four keys to the sides of the display for the XLE and at the bottom of
the screen for the XLT). Pressing the soft key will switch to the screen that is programmed.
