Description: Communications Module | IC693CMM311
Type of Device: Communication Module, CCM, RTU, SNP, and SNPx Protocols
Product Description: The Communications Coprocessor Module (IC693CMM311) provides a high performance coprocessor for all Series 90-30 modular CPUs (cannot be used with embedded CPUs - models 311, 313, or 323). This module supports the GE Fanuc CCM communications protocol, the RTU (Modbus) slave communications protocol, and the SNP protocol. This module has two serial ports. Port 1 supports RS-232 applications and Port 2 supports either RS-232 or RS-485 applications. The module can be configured using the configuration software, or by using a default setup. Since both serial ports are wired to the module?s single connector, an IC693CBL305 Wye cable is supplied with this module to separate the two ports for ease of wiring. A system with a 331 or higher CPU can have up to four CMMs (in the CPU baseplate only).
Communication Ports: 1 RS-232, (1) RS-485
Internal Power Supply: 400 Milli-Amp at 5 Volt DC

Protocol Support: SNP/SNPX, CCM, Modbus RTU Slave
Feature: Choose from ethernet EGD, profibus-DP, genius, deviceNet, interbus-S, series 90 Protocol (SNP) and RTU modules
Serial Ports: The Series 90-30 CMM has a single serial connector which supports two ports. Port 1 applications must use the RS-232 interface. Port 2 applications can select either the RS-232 or RS-485 interface.
Serial Port Pin Assignments: The RS-485 signals for port 2 and the RS-232 signals for port 1 are assigned to the standard connector pins. The RS-232 signals for port 2 are assigned to normally unused connector pins.
IC693CBL305 Wye Cable: A Wye cable (IC693CBL305) is supplied with each Series 90-30 CMM and PCM module. The purpose of the Wye cable is to separate the two ports from a single physical connector (that is the cable separates out the signals). In addition, the Wye cable makes cables used with the Series 90-70 CMM fully compatible with the Series 90-30 CMM and PCM modules.
