IC693CMM311

The IC693CMM311 is a communications coprocessor module from the Series 90-30 PLC platform. This series of PLC particularly the IC693CMM311 is formerly manufactured by GE Fanuc however, recently acquired by Emerson Automation. This module provides CCM, Remote Terminal Unit (RTU), and SNP connectivity to any controller that hosts the module. Specifically, the IC693CMM311 is compatible for use with modular Series 90-30 CPUs. The IC693CMM311 comes with Two (2) communication interfaces such as Port 1 supporting RS232 standard and Port 2 supporting RS232 / RS422 and RS485 electrical standards. Each port is a 25-pin D-shell interface. This module is provided with a push to restart the communication button to re-initiate communication without restarting the entire module. The IC693CMM311 ports are configurable for a variety of protocol combinations such as CCM protocol on both ports; CCM protocol on port 1, RTU protocol on port 2; RTU protocol on port 1, CCM protocol on port 2; RTU protocol on both ports; SNP and SNP-X protocols on both ports; SNP and SNP-X protocols on port 1, CCM protocol on port 2; CCM protocol on port 1, SNP and SNP-X protocols on port 2; SNP and SNP-X protocols on port 1, RTU protocol on port 2; RTU protocol on port 1, SNP and SNP-X protocols on port 2. Supported transmission speeds for CCM, SNP, and RTU are 300, 600, 1200, 240, 4800, 9600, and 19200 Baud rate. Compatible pre-assembled cable is the Wye connection cable with catalog number IC693CBL305. This module comes with MODULE OK, PORT 1 and PORT 2 tatus LED indicators for determining the module’s state of operation.

The IC693CMM311 module is part of the Series 90-30 by GE Fanuc as a CCM or Communications Coprocessor Module. It is designed to be a high-performance device. The GE Fanuc Series 90-30 IC693CMM311 communications coprocessor module is compatible with all of the modular CPUs in the GE Series 90-30 product line, but it cannot be used with any of the embedded GE Series 90-30 CPUs such as the 311, 313, or 323 embedded GE CPUs. Any GE Fanuc Series 90-30 PLC with a modular CPU will benefit from the installation of the GE IC693CMM311 communications coprocessor module and all of its features and functions. The protocols that this communications coprocessor module can support are the SNP protocol, the Modbus or RTU slave communications protocol, and the GE Fanuc CCM communications protocol. The GE Fanuc Series 90-30 IC693CMM311 communications coprocessor module has 2 built-in serial ports known as Port 1 and Port 2. The applications supported by Port 1 are RS-232 applications and the applications supported by Port 2 are RS-232 applications and RS-485 applications. Both of the ports are wired to the IC693CMM311 communications coprocessor module’s one and only connector, which can make wiring the module difficult, but the module comes with a GE Wye cable known as the IC693CBL305 Wye cable that technicians can use to separate the 2 ports and make wiring the module easier. The module can be configured with a default setup or with configuration software. Certain CPUs (models 331 and later) can support up to 4 of these communications coprocessor modules at a time in their CPU baseplates.
