PACSystems™ RX3i IC695CMM002 and IC695CMM004 GFK-2461E January 2010 Serial Communications Modules 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 backplane. MODULE OK PORT FAULT P1 P2: P3: P4: 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. STATUS 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. STATUS PORT 1 PORT 2 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.

Supports CCM Slave Protocol Initial Release Upgrades The Serial Communications Modules can be upgraded to firmware version 1.32 using the following upgrade kits, which can be downloaded from http://www.ge-ip.com/support CMM002: 44A753277-G05 CMM004: 44A753278-G05 Compatibility Programmer Version Requirements Proficy® Machine Edition Logic Developer 5.9 SP1 with SIM 6 is required for half duplex flow control Proficy Machine Edition Logic Developer 5.8 with SIM 2 or newer is required to use SPL Proficy Machine Edition Logic Developer 5.6 with SIM 10 or newer is required to use DNP3 Proficy Machine Edition Logic Developer 5.6 with SIM 6 or newer is required to use the CMM CPU Firmware Version Requirements PACSystems RX3i CPU Version 5.50 or newer is required for SPL PACSystems RX3i CPU Version 5.50 or newer is required for SPL. PACSystems RX3i CPU Version 5.00 or newer is required for DNP3 Master to sync its timestamp value with the CPU. PACSystems RX3i CPU Version 3.83 or newer is required to be able to use the CMM in the RX3i system. New for Release 1.32 Enhanced Configuration for Serial Port Flow Control Releases 1.32 and later support half duplex flow control and full duplex control. Flow control is configurable with Proficy Machine Edition Logic Developer 5.9 SP1 with SIM 6. Full duplex flow control is the default flow control. Releases 1.30 and earlier support full duplex flow control only. 3 RX3i Serial Communications Modules GFK-2461E Problems Resolved in Release 1.32 SPL - ASCTOVAL function would not accept negative sign Releases 1.32 and later will allow leading negative sign in char arrays passed into ASCTOVAL SPL - ASCTOVAL function would over write trailing byte in SRC array ASCTOVAL writes null to source array byte that follows last converted byte by command DNP3- Multiple Block Writes were not allowed in single request In Release 1.30 (only) multiple Control Relay Output Block (CROB) and multiple Analog Output Block (AOB) writes were not allowed in a single request. Release 1.32 allows multiple Control Relay Output Block (CROB) and multiple Analog Output Block (AOB) writes. SPL – ‘dot’ notation for integer values did not work The 'dot' notation (variable subscript reference GFK-2460C pg 9-11) allows each byte in an integer to be addressed. This ability was not working correctly from the command line interface (CLI) to the module. A script, such as this following example, would correctly reference the byte. DIM iMyInt INTEGER iMyInt = 256 PRINT "iMyInt.1 = " & iMyInt.1 The command line would not. 1>RUN iMyInt.1 = 1 1> print iMyInt.1 256 This value of 256 should be 1. This functionality now behaves as expected from the command line interface. SPL – Serial.clear command did not work SPL SERIAL.clear commands did not work. This has been corrected in Firmware revision 1.32. SPL displayed error -3 when PUTB buffer overflowed. SPL displayed error -3 when PUTB buffer overflowed. In firmware version 1.32 the correct error is displayed when PUTB buffer is overflowed as follows: Reason: code[53] serial transmit buffer overflow 4 RX3i Serial Communications Modules GFK-2461E Restrictions and Open Issues in this Release 1. The module will reject 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. 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 special MODBUS commands for use with a Daniels Flow Computer. 5. PLC Reference Address Parameters will 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. 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. 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). 8. The DNP3 slave port has problems using the link layer to validate frame receipt. The DNP3 organization encourages users not to do this. 5 RX3i Serial Communications Modules GFK-2461E Operating Notes 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 The maximum resolution for the MODBUS drop delay is 420μs, so the minimum time for a drop delay is 420μs.

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. 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.
