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.

Installation and Maintenance Requirements document, GFK-2975.

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.
