Serial Communications Modules
April 2018
PACSystems* RX3i Serial Communications modules expand the serial
communications capabilities of the RX3i system.
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 backplane1.
The IC695CMM00xCA modules are the conformal-coated versions of the
IC695CMM00x modules.
The IC695CMM004LT version is for low temperature applications (-40°C).
Each port can be configured for MODBUS Master, MODBUS Slave, CCM Slave,
DNP3 Master, DNP3 Slave, or Serial I/O protocol. If any port is configured for
DNP3 Master or Slave, the other ports on the module can only be configured for
DNP3 Master or Slave.
For modules with firmware version 1.32 or later, half-duplex flow control can be
configured using Machine Edition Release 5.90, SP1, SIM 6 or later. Otherwise,
flow control defaults to full-duplex.
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, RFR/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 most recent version of the PACSystems RX3i System Manual,
GFK-2314.

Description
Defect
#15825
When running a single port in RS232 Serial ASCII mode, communication errors can occur at all baud rates and all data
payload sizes. When running four ports, RS232 Serial ASCII mode, communication errors are seen at baud rates below
4800 baud with payloads of 1024 bytes. With four ports and baud rates below 4800 baud, the payloads of 100 bytes
or less work properly.

Restrictions and Open Issues in this Release
SPL
1. The module rejects a SPL program file containing a literal string of length greater than 127. The SPL port will
return a status in the status byte of 61.
2. The static file checker can miss paired NEXT and FOR statements. If a NEXT statement is missing from the
program, execution will continue without looping back to the FOR statement. Users should check their
FOR/NEXT statements before downloading. A missing NEXT statement can also be detected by debugging
using the CLI debug interface.
Other
3. Each port can be configured for DNP3 Master or DNP3 Slave protocol. If any port is configured for DNP3 Master
or Slave, the other ports on the module can only be configured for DNP3 Master or Slave.
4. These modules do not support GE Intelligent Platforms special MODBUS commands for use with a Daniels Flow
Computer.
5. PLC Reference Address and Reference Length parameters only allow bit based memory values that are aligned
to a byte boundary.
For example, for a port using MODBUS Slave with coils mapped to %Q memory, the %Q memory address must
start on a byte boundary in %Q. (Target Address 1 can be mapped to %Q00001 or %Q00009, but it can not be
mapped to %Q00007.)
6. CCM Slave Read Scratchpad operations may fail 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.
7. The DNP3 slave port has problems using the link layer to validate frame receipt. The DNP3 organization
encourages users not to do this.
8. Change Event Read responses are not sent immediately after a Confirm to an unsolicited response.
If a read request is received after sending an unsolicited response, the slave is required to wait to respond to
the read until either the unsolicited timeout expires, or the unsolicited message is confirmed.
The module waits until the timeout expires, even if the unsolicited message has been confirmed, to send the
read response.
Normally, messages are responded to within milliseconds, but the read response does not occur for up to 2
seconds after the confirm message is sent.

Operating Notes
•Due to the re-designed nature of the obsolescence change, minor performance differences may exist
between the V1.xx and V2.00 hardware/firmware versions.
SPL
1. In the error message, brackets [ ] are printed only around the key failing token. When looking at the error
message the entire line should be interpreted.
Example:
--- Script file ---
i = 128 )
--- Error output---
Error [3184]: line 1
i = [128] )
2. An SPL wrong error is reported when a “(“ is in an IF statement. IF statements only support comparisons of
variables and constants. Using () to enclose operations (like arithmetic operations or comparisons) will result in
a syntax error. The module will report this error as an unknown identifier for the () symbols rather than a syntax
error.
3. If the SPL program writes to memory that is invalid in the PLC the write will fail and the SPL program will halt.
Other
1. DNP3.0 configurations with Unsolicited Response support enabled or Analog Input Event Variations set to other
than 16 Bit Values Without Time, will result in a System Configuration Mismatch fault. If any of these
configuration is downloaded to a module with firmware earlier than Release 1.34, the module configuration will
fail.
2. The maximum resolution for the MODBUS drop delay is 420μs, so the minimum time for a drop delay is 420μs.
3. If retentive memory is used for Port Control Data, when a power cycle with battery or hot swap of the CMM
module occurs, all exchanges whose control bit is in the ON state will be re-executed on the next PLC output
scan or output DO I/O. To prevent this, all exchange control bits must be cleared by the application logic on the
initial PLC logic scan or upon detection of CMM module removal.
