2.3 Detailed Product Descriptions
a. Features
The RX-371 combines several desirable functions in one compact package. Each unit is a highly
integrated operator interface and controller with expandable I/O and networking capabilities have
standard features consisting of the following:
• Metal enclosure with aluminium front and steel back cover.
• Bright, 32000 Color graphical Touch sensing LCD display
• Domed keypad with magnetic contact.
• Plastic touch screen that is thicker and more damage resistant.
• Display of complex graphical objects including trends, gauges, meters and animations.
• CsCAN Networking port
February 8, 2010 Page 13 of 124 # 1018
CH. 2 MAN0924-01-EN
• RS-232 / RS-485 Serial Ports
• Configurable serial protocols for communication to drives, PLC’s, or other serial peripherals.
• Advanced control capabilities including floating point, multiple auto tuning PID loops and string
handling capabilities.
• Removable Media for up to two gigabytes of storage of programs, data logging or screen captures.
• System Key and Configurable Function Keys
• USB networking port for communication with PC’s and programming of controller.
• USB supporting flash drive.
• Ethernet (10/100 Mbps)
• Smart Stack I/O Expansion and Smart Stix remote I/O.
• Cscape programming software allowing all aspects of RX-371 to be programmed and configured from
one integrated application.
b. CsCAN Network
The RX-371 has the CsCAN networking port for communication with remote I/O, other controllers or PC’s.
(CsCAN is pronounced “see-scan”). CAN-based network hardware is used in the controllers because of
CAN’s automatic error detection, ease of configuration, low-cost of design and implementation and ability
to operate in harsh environments. Networking abilities are built-in to the RX-371 and require no external
or additional modules.
Figure 2.3: Pass through Function (Available in CsCAN Networks Only)
The RX-371 features the ability to pass through programming commands. When attached to a RX-371
serial port, a programming package (i.e., Cscape) can access other RX units or any other OCS unit
connected to a CsCAN network by passing the programming command through the serial port to the
network port. One Cscape package (connected to one RX unit) can program all RX or other OCS units on
the CsCAN network. When several RX models are networked together to achieve a specific purpose, the
system acts like a large parallel-processing controller.
c. Cscape Software
RX-371 hardware is programmed with a Windows-based PC application called Cscape (HE500OSW232).
Cscape (pronounced “see-scape”) stands for Control Station Central Application Programming
Environment. Provided there is one serial connection to one node on the network (i.e., CsCAN
Network), the operator has control over the entire system. The operator can upload, download, monitor
and debug to any node on the network.
This application can be used to program, configure, monitor and debug all aspects of the RX-371 unit. It
is used for programming RX-371 OCS ladder logic, programming user displays for the RX-371 OCS,
configuring the network for global digital and analog data, setting system-wide security and monitoring
controllers in the system.

3.6 Factors Affecting Panel Layout Design and Clearances
Warning: It is important to follow the requirements of the panel manufacturer and to follow
applicable electrical codes and standards.
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 RX-371 OCS)
2 inches (50.80mm)
3.6.2 Grounding
Warning: Be sure to meet the ground requirements of the panel manufacturer and also meet
applicable electrical codes and standards.
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 p anel door.
3.6.4 Orientation
When panel-mounted, there are no orientation restrictions on the RX-371 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 RX-371 OCS and noisy devices
such as relays, motor starters, etc.
February 8, 2010 Page 20 of 124 # 1018
MAN0924-01-EN CH.3
3.6.6 Shock and Vibration
The RX-371 OCS has been designed to operate in typical industrial environments that can inflict some
shock and vibration on the unit. For applications that can inflict excessive shock and vibration, use proper
dampening techniques or relocate the RX-371 OCS to a location that minimizes shock and / or vibration.
3.7 Panel Layout Design and Clearance Checklist
The following list provides highlights of panel layout design factors.
____Meets the electrical code and applicable standards for prope r 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 RX-371?
____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 RX-371 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?

4.2 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 (RF) interference.
4.3 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
ohms. Horner APG recommends less than 15 ohms resistance from our equipment to ground.
Resistance greater than 25 ohms can cause undesirable or harmful interference to the device.
4.4 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 RX-371 OCS 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 (although MJ2 can now
be used as well) for RX-371 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 both a half-duplex RS-485 interface and an RS-232 interface with RTS/CTS
handshaking.
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.

r
The DIP Switches are used fo
termination of the RS-485 ports. The
RX-371 is shipped un-terminated.
To terminate, select one of the DIP
Switches and configure it based upon
the option that is desired.
SW1 - ON enables MJ2 RS485 port
termination (121 Ohms).
OFF disables MJ2 RS485 port
termination.
SW2 & SW3 - ON places MJ2 RS485 port in
half-duplex mode.
OFF places MJ2 RS485 port in full-
duplex mode.
SW4 - ON enables MJ1 RS485 port
termination (121 Ohms).
OFF disables MJ1 RS485 port
termination.
5.4 RS-485 Termination
Proper RS-485 termination minimizes reflections and improves reliability.
Both serial ports allow an internal RS-485 termination resistor to be placed across pins 1 and 2 by DIP
Switch Setting.
the two devices physically located at the endpoints of the RS-485 network should be terminated.
Only
5.5 RS-485 Biasing
RS-485 biasing passively asserts a line-idle state when no device is actively transmitting, whic h is useful
for multi-drop RS-485 networking.
Both 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 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
The RX-371 OCS MJ1/MJ2 serial port supports CsCAN Programming Protocol. If a PC COM port is
connected to the RX-371 OCS MJ1/2 serial port, Cscape can access the RX-371 OCS 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 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.

CHAPTER 6: CAN COMMUNICATIONS
Note: For additional CAN information, refer to the CAN Networks manual (
6.1 Overview
All RX-371 OCS models provide a CAN networking port, which is implemented with a 5-pin connector.
The connector is labeled NET1.
MAN0799) on our website.
Figure 6.1: NET 1 Connector
Like the MJ1 serial port, the NET1 port can be used for RX-371 OCS programming by connecting it to the
CAN port of a PC running Cscape. The NET1 port also allows the RX-371 OCS to exchange global data
with other OCS/RCS controllers and to access remote Network I/O devices (SmartStix Modules).
6.2 Port Description
The RX-371 OCS NET1 port implements the ISO 11898-2 physical layer and the CAN 2.0A data link
layer standards. Also, since the NET1 port is powered by an internal isolated power supply, external
CAN power is not required.
6.3 CAN (NET1) Port Wiring
This section shows how the CsCAN port pins are assigned.
Note: The V+ connection is not
required on the RX-371 OCS.
The RX-371 OCS 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.

6.4 Cscape Programming via CAN
The NET1 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 RX-371 OCS NET1 port, Cscape can access the
RX-371 OCS for programming and monitoring.
In addition, the RX-371 OCS supports single-point-programming of all OCS devices that are connected to
a CAN network. If the PC COM port is connected to the RX-371 MJ1 serial port, it can act as a passthrough gateway allowing Cscape to access all OCS 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 OCS 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 Modules) to the NET1 port allows the RX-371 OCS I/O to be
economically expanded and distributed. A variety of SmartStix Modules are available for this purpose.
