More Information

Overview Manuals Protocols Serial Ports Compatibility Applications

Features:

  • Supports CCM, RTU slave, and SNP serial protocols
  • One RS-232 port plus one RS-232/RS-485 selectable port
  • Up to four modules can be used with CPU331 or later
IC693CMM311 is the dedicated serial-communications processor for modular Series 90-30 controllers.

Two independently accessible ports let the rack serve programming, host, and device links without assigning every communication task to the CPU.

Its baseplate and CPU restrictions make controller compatibility a required selection step.

The General Electric IC693CMM311 Series 90-30 communications coprocessor module may remain available for quotation and installed-system support from Apter Power.
General Electric IC693CMM311 Series 90-30 communications coprocessor module Manuals, Datasheets, LinksImportant Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Supported serial services

  • CCM: The module implements GE Fanuc CCM communication for compatible hosts and controllers.
  • RTU slave: Modbus RTU slave service allows a serial master to exchange mapped PLC data.
  • SNP: Series Ninety Protocol supports compatible programming and controller communications.
  • Configuration: Protocol and port parameters can be established with supported Series 90-30 engineering software.

Electrical interfaces

  • Port 1: The first channel uses an RS-232 electrical interface.
  • Port 2: The second channel can operate as RS-232 or multidrop-capable RS-485.
  • Supplied cable: IC693CBL305 is the associated cable identified for module setup and connection.
  • Channel separation: Each port is assigned parameters suited to the device attached to that connector.

CPU and rack limits

  • CPU baseplate: IC693CMM311 is installed only in the baseplate containing the modular CPU.
  • Excluded CPUs: Embedded CPU311, CPU313, and CPU323 do not support this coprocessor.
  • Module count: CPU331 and later systems can configure as many as four CMM modules.
  • Project match: The hardware location and serial setup must agree with the stored PLC configuration.

Supported communication uses

  • SCADA links: An RTU master can poll process data from the controller through the slave port.
  • Serial programming: SNP service supports compatible programming and maintenance access.
  • Legacy hosts: CCM enables established computer-to-PLC data exchanges.
  • Multidrop devices: The RS-485-capable second port can connect compatible nodes on a shared serial network.
Description
IC693CMM311 is a serial communications coprocessor that offloads protocol work from a modular Series 90-30 CPU for connected hosts and industrial devices.

In IC693CMM311, port 1 operates as RS-232, while Port 2 can be configured for RS-232 or RS-485. The module supports CCM, RTU slave, and SNP operation and can be configured from Logicmaster 90, VersaPro, or its applicable default setup.

For installations using IC693CMM311, iC693CMM311 belongs in the CPU baseplate and is not supported with embedded CPU models 311, 313, or 323. Systems using CPU331 or later can accommodate as many as four CMM modules, subject to configuration and rack resources.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can IC693CMM311 operate as a Modbus RTU master?
The communications coprocessor provides RTU slave operation, so the connected serial master initiates the Modbus transactions.
Which cable is supplied for IC693CMM311 serial access?
The IC693CBL305 Wye cable separates the module connector into the two serial communication paths.
Why is IC693CMM311 rejected beside a CPU323?
Embedded CPU311, CPU313, and CPU323 systems do not support IC693CMM311; the coprocessor requires a compatible modular CPU.
Where must IC693CMM311 be installed?
A configured communications coprocessor must occupy a slot in the modular CPU baseplate; Series 90-30 expansion and remote baseplates are not supported locations.
How many IC693CMM311 modules can a CPU331 system use?
The selected communications coprocessor can be configured up to four times with CPU331 or later, subject to rack and project limits.
Which protocols are available on IC693CMM311?
The unit supports CCM, Modbus RTU slave, and SNP communication services.
What should be restored after replacing IC693CMM311?
Its port mode, protocol selection, baud rate, addressing, and serial wiring should be matched to the original project.
