        Overview Manuals Interface Choice Serial Framing CCM Messaging Distance Extension

        Features:

        • Implements GE Fanuc CCM2 communications for Series Five data exchange.
        • RS-232C and RS-422 connectors support short local and longer differential links.
        • PLC logic can originate messages for application-controlled communication.
        The module exposes one logical port through two electrical interface choices. The connected device, cable, and configuration must all use the same intended standard.

        Asynchronous communication is configurable from 300 to 19,200 baud. Framing and protocol agreement should be proved with a simple transaction before the full application is restored.

        Long or isolated RS-422 installations may use the IC655CCM590 adaptor. Cable topology and station roles should be documented as part of the system, not inferred from connector type alone.

        GE Fanuc IC655CCM500 CCM Communications Module Manuals, Datasheets, Links Important 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.

        Selecting RS-232C or RS-422

        • RS-232C: Use for a compatible short local serial connection.
        • RS-422: Use differential signaling for the documented longer run.
        • One logical port: Do not treat both connectors as independent channels.
        • Cable record: Preserve pinout, polarity, shield, and station role.

        Settings required before CCM data can pass

        • Baud rate: Both ends must use the same selected speed.
        • Character format: Match start, data, parity, and stop-bit settings.
        • Half duplex: Coordinate which station is permitted to transmit.
        • Error checks: Parity and LRC help identify corrupted messages.

        Connecting protocol exchanges with PLC logic

        • CCM2 protocol: Use commands supported by the connected device.
        • Station identity: Keep each communicating endpoint correctly defined.
        • PLC originator: Ladder logic can request selected transfers.
        • Commissioning: Prove a small transaction before restoring the full sequence.

        Planning communication beyond a local cable

        • Direct RS-422: A compliant differential segment can reach the documented distance.
        • Adaptor use: IC655CCM590 can repeat or convert an appropriate link.
        • Modem path: A modem supports communication beyond direct-cable limits.
        • Noise control: Preserve shield, routing, and termination across every segment.
        Description
        General Electric IC655CCM500 is a Series Five CCM Communications Module that provides a serial data path to compatible computers, operator interfaces, modems, and other intelligent equipment. It implements the GE Fanuc CCM2 protocol and permits selected transfers to be initiated from ladder logic.

        One logical channel on IC655CCM500 is presented through separate RS-232C and RS-422 connectors. The installation uses the appropriate electrical interface with matching baud, parity, framing, station role, and cable pinout at the remote device; the two connectors are not independent communication ports.

        Direct RS-232C wiring is intended for a short local link, whereas the differential RS-422 side of IC655CCM500 supports the longer documented cable distance. A modem or an IC655CCM590 adaptor may extend a suitable installation, but neither device corrects an incompatible CCM message or station configuration.

        Several IC655CCM500 modules may occupy the CPU base when separate serial channels are required. Its eight indicators help locate activity and error conditions, after which testing can proceed in order from physical wiring to character framing, station setup, and finally protocol content.

        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.
        VIEW ALL FAQS
        Why does IC655CCM500 show activity but no valid data appears at the other device?
        When reviewing the IC655CCM500 configuration, compare interface type, station role, baud, parity, character framing, and CCM message format; electrical activity alone does not prove protocol agreement.
        Can both IC655CCM500 serial connectors be used as independent ports?
        The practical answer for IC655CCM500 is clear: No. They are alternate electrical interfaces for one logical communication port, so the installation should use the connection defined by the system design.
        With IC655CCM500, what should be checked when an RS-422 link fails only at long distance?
        At the IC655CCM500 communication pathinspect cable type, polarity, shield, end termination, topology, and total length, then verify whether a repeater or isolation adaptor is required.
        Why may IC655CCM500 communicate after power-up but fail during production?
        When working with IC655CCM500, look for noise coupling, loose connectors, station conflicts, message timing, or application traffic that exceeds the assumptions of the simple startup exchange.
        How should an IC655CCM500 replacement be prepared?
        On IC655CCM500, save station and serial settings, ladder-originated message definitions, cable pinout, interface choice, and the identity of every remote device before removal.
        When is IC655CCM590 relevant to an IC655CCM500 network?
        During IC655CCM500 troubleshooting, use it where the RS-422 design needs electrical isolation, conversion from RS-232, or another documented 4000 ft differential segment.
        With IC655CCM500, how can protocol and wiring faults be separated?
        In an IC655CCM500 installation, first prove idle levels and a simple known character exchange on the selected interface, then test a minimal CCM transaction before enabling the complete application sequence.
