CCM, RTU and SNP are available on either or both serial ports in any of nine possible configurations: CCM/CCM, CCM/RTU, RTU/CCM, RTU/RTU,SNP/SNP,SNP/CCM,CCM/SNP,SNP/RTU, and RTU/SNP . 1 SHIELD 2 TD 3 4 RD RTS 5 7 CTS GROUND DCD * * DTR 8 20 PORT 1 & 2 RS–422 PIN SIGNAL 7 GROUND 9 10 SD (A) RTS (A) 11 12 * CTS (A) * TERM PIN 11 13 21 RD (A) SD (B) 22 RTS (B) 23 24 25 The CMM provides both the RS-232 and RS-485 Interfaces and communicates with the PLC CPU over the backplane.

SNP is the native protocol of all IC69* PLCs. SNP is a master-slave protocol, where the slave device responds to requests from the master. An SNP slave device is built into every IC69* PLC. Each serial port on the CMM can be configured to provide SNP master or slave capability. In the master and peer CCM configurations, the CMM module initiates communications with remote devices through application ladder program communications requests (COMREQs). RTU: The RTU mode of operation is a query/response protocol used for communicating between the CMM and a host computer. The host computer is the master device and transmits the query to the RTU slave which responds to the master. In RTU mode, only slave configuration is available. In the RTU slave protocol, the following functions are provided: read input and output tables (%I and %Q), read analog input (%AI), read register table (%R), read scratchpad, read exception status, force a single or multiple output(s) (%Q), preset a single or multiple register(s) (%R), report the device type, and perform loopback maintenance. 71-2 The SNP protocol on the CMM module provides read and write access to PLC memory (types %R, %I, %Q, %AI, %AQ, %T, %M, %P, %L, and %G), full Series 90 Datagram support, and many status and control functions. An Autodial feature is also provided to control a modem attached to an SNP master port. The SNP-X extensions to SNP provide easy-to-use, high performance read and write access to PLC memory (types %R, %I, %Q, %AI, %AQ, %T, %M, and %G). SNP-X is especially useful for simple, high-speed data acquisition and control in multidrop configurations. As an SNP master, the CMM module initiates communications with remote devices through application ladder programs communication requests (COMREQS). An SNP master port on a CMM module can communicate with the SNP slave port built into any IC69* PLC, or with other SNP slave devices. As an SNP slave, the CMM module provides additional communications port(s) for connection to remote operator interface units or other SNP communications devices. The MS-DOS or Windows based software package may be connected to an SNP slave port on a CMM module for data monitoring only. Programming and configuration of IC69* PLCs are not possible through the CMM SNP ports. t Series 90 -70 Programmable Controller Data Sheet Manual GFK-0600F Communications Modules 3 GFK-0370F August 1997 Communications Coprocessor Module (CMM) Systems Configuration Figure 2 illustrates typical CMM interface installations in a IC69* PLC system. a45299 PARALLEL ÎÎÎÎ Î ÎÎÎÎ ÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎ Î Î ÎÎÎÎÎÎÎÎ IC697 PLC (RACK 0) Î P S C B C C P T M M U M M M G B C ONE METER PROGRAMMER (GENERIC) PC IC697 PLC (RACK 1) B R M Î C M M Î (GENERIC) PC MASTER CCM DEVICE PEER CCM DEVICE ÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎ (GENERIC) PC IC697 PLC (RACK 6) NOTE Î Î B C R M M M ALL RACKS MUST BE AT SAME GROUND POTENTIAL (8 RACKS MAXIMUM).
