IC695CMM002 and IC695CMM004

PACSystems RX3i Serial Communications modules expand the serial
communications capabilities of the RX3i system.

MODULE OK

PORT FAULT

Serial Communications module IC695CMM002 provides two
independent, isolated serial ports. Serial Communications module
IC695CMM004, illustrated at right, provides four independent, isolated
serial ports. Up to six Serial Communications modules can be located

in the main PACSystems RX3i backplane.

Each port can be configured for MODBUS Master, MODBUS Slave, or
Serial I/O protocol. In addition, for modules that are version 1.10 or

STATUS

PORT 1

later, each port can be configured for CCM Slave protocol using
Proficy Machine Edition 5.6, SIM 6 or later. For modules that are
version 1.20 or later, each port can be configured for DNP3 Master or
DNP3 Slave protocol using Machine Edition 5.6 SIM 10 or later. If any

STATUS

PORT 2

port is configured for DNP3 Master or Slave, the other ports on the
module can only be configured for DNP3 Master or Slave.

Additional module features include:

▪ Port-to-port isolation and port-to-backplane isolation

▪ RS-232, RS-485/422 communication, software-selected

▪ Hardware handshake: RTS/CTS for RS-232

▪ Selectable Baud Rates: 1200, 2400, 4800, 9600, 19.2K, 38.4K,

57.6K, 115.2K

▪ Module fault status reporting (Watchdog, Ram Fail, Flash Fail)

▪ Module identity and status reporting, including LED status

indicators

▪ Meets CE, UL/CUL 508 and 1604, and ATEX requirements

▪ Flash memory for future upgrades

These modules must be located in an RX3i Universal Backplane.

RX3i Serial Communications can be hot-inserted and removed
following the instructions in the PACSystems RX3i System Manual,
GFK-2314.

Supports CCM Slave Protocol

Supports DNP3 Master and DNP3 Slave Protocol

New for this Release

This release of the RX3i Serial Module adds support for Distributed Network Protocol 3.0 Master and Slave to the
other protocols: MODBUS Master/Slave, CCM, and Serial I/O. This module does not operate with COMMREQs
but rather uses preconfigured mappings of the I/O reference memory.

MODBUS Master and MODBUS Slave Protocols now support the configuration of 1 stop bit, for compatibility with
some GE Fanuc Automation MODBUS Slaves.

Compatibility

Programmer: Proficy® Machine Edition Logic Developer 5.6 with Service Pack 2 SIM 10

RX3i CPU: PACSystems RX3i CPU Version 5.00 or later is required to be able to use the time

synchronization feature on a DNP3 Master port.

Problems Resolved for This Release

When parity is set to none in the port configuration for the Modbus Master or Modbus Slave protocols, the stop
bits were forced to 2. This restriction has now been removed and the stop bits can be set to 1 or 2.

RX3i Serial Communications Modules 3

GFK-2461B

Restrictions and Open Issues in this Release

1. When multiple group objects (i.e. %I and %AI memory) are read in a single request, the DNP3 port will

ignore all but the first object. Operations of multiple group objects should be split into multiple successive
exchanges (i.e. exchange 1 - %I, exchange 2 - %AI).

2. The DNP3 slave port has problems using the link layer to validate frame receipt. The DNP3 organization

encourages users not to do this.

3. These modules do not support GE Fanuc special MODBUS commands for use with a Daniels Flow

Computer.

4. PLC Reference Address and Reference Length Parameters do not support bit length/start. Bit and Non-

Byte Length operations must begin on a byte boundary.

5. When a port is configured for CCM Slave protocol, and:

▪ a new configuration is stored to the PLC using Machine Edition, or

▪ the system is power-cycled, or

▪ the module is hot-inserted,

if the first query received from the CCM Master is a Read Scratchpad request, the module will reject that
request. All subsequent Read Scratchpad requests will be successful unless one of the above conditions
occurs again.

Operating Notes

The maximum resolution for the MODBUS drop delay is 420us, so the minimum time for a drop delay is 420us.

The Module OK LED indicates the status of the module. Solid
green indicates that the module has been configured. The
Module OK LED is off, if the module is not receiving power from
the R3i backplane, or if a serious module fault exists.

At powerup, the Module OK LED flashes green/off while the
module is executing powerup diagnostics. It then flashes more
slowly as the module receives its configuration from the CPU.

If a problem occurs, the Module OK LED flashes amber, The
blink code (see below) indicates the cause of the error.

1 = watchdog expired
2 = RAM error
6 = Invalid CPU Master Interface version
7 = CPU heartbeat failure
8 = Failed to get semaphore

The Port Fault LED indicates the status of all ports. The Port
Fault LED is green when there are no faults present on any
enabled port. If this LED turns amber, there is a fault on at least
one port.

A port’s Status LED flashes green when there is activity on the
port.

IC695CMM004

The area below the module LEDs can be used to record
identifying information about each port.

Serial Ports

Each port is a standard RJ-45 female connector with the following pin assignments. For MODBUS applications,
note that these pin assignments are different than the standard MODBUS pin assignments. If the port is
configured for MODBUS master or slave operation, custom cables are needed.

Termination

By default, each port is set for no termination. Termination is needed if the module is the first or last device on an
RS-485 network, even if there is only one other device on the network. Termination can be provided using either
an external resistor as shown below or the port’s built-in 120-Ohm termination. If line termination other than 120
Ohms is required, an appropriate external resistor must be supplied.
