        Features:

        • Provides two configurable serial communication ports for the Series Six CPU.
        • Supports RS-232 and RS-422 electrical interfaces under the CCM protocol.
        • Allows ladder-controlled data transfer through Serial Communications Requests.
        IC600CB516 connects the Series Six processor with computers, terminals, modems, operator interfaces, and other compatible devices.

        Its two ports can serve different physical links, but the device role, timing, and cable arrangement must agree at both ends.

        IC600CB536 is the designated later substitute for IC600CB516, so the preserved communication configuration is essential to a controlled changeover.

        For General Electric IC600CB516 Type 2 Communications Control Module replacement sourcing and documentation support, contact Apter Power.

All prices are shown in USD.

        Capture both channels as separate interfaces

        • Serial interface: Record the RS-232 or RS-422 selection, baud rate, station address, master or slave role, timeout, and connected device for each IC600CB516 port.
        • Protocol selection: A port can be electrically correct yet remain silent when its protocol role or address differs from the host.
        • Message path: Preserve known-good messages and the host-side configuration.
        • Channel checkout: Reconnect and test one channel at a time during commissioning.

        Trace communication back to ladder logic

        • Register handling: IC600CB516 can originate transfers under control of Serial Communications Request blocks.
        • Register state: Inventory the registers, command values, and trigger conditions used by the application.
        • Cable path: A request error should be separated from cable, port, and remote-device faults.
        • Configuration record: Record the observed status words before resetting the exchange.
        • Transaction test: After replacement, prove read and write paths with safe test data before normal commands resume.

        Match distance and topology to the interface

        • Grounding: RS-232 is intended for a short direct IC600CB516 connection.
        • Serial standard: RS-422 supports the longer run and multidrop arrangement when cable and grounding rules are followed.
        • Cable path: Verify connector pinout, shield termination, signal pairs, and ground potential rather than reusing a cable by appearance alone.
        • Modem signals: For modem links, include the modem timing and control signals in the test plan.

        Validate the later CCM2 as a system change

        • Operating context: IC600CB536 replaces IC600CB516 in the Series Six ordering path, so the move must be treated as a controlled communication migration.
        • Protocol selection: Compare rack position, electrical interfaces, port settings, protocol behavior, and ladder requests before installation.
        • Configuration record: Keep the original module and configuration available for rollback.
        • Device validation: Sign off each attached device independently after successful transactions are captured.
        Description
        General Electric IC600CB516 is the earlier Series Six Communications Control Module Type 2, or CCM2. Two serial ports provide RS-232 and RS-422 electrical interfaces for intelligent devices using the CCM protocol.

        A direct RS-232 connection serves short links, while RS-422 extends the cable run for supported point-to-point or multidrop arrangements. Modems allow longer-distance communication where the direct electrical interfaces are unsuitable.

        Under ladder control, the Serial Communications Request function can initiate transfers involving register, input, output, override, scratchpad, and user-logic areas. IC600CB516 can also support programming recorders, an Operator Interface Unit, a terminal, or a printer in the documented configuration.

        IC600CB536 is the designated later substitute for IC600CB516. A replacement plan should capture port mode, baud rate, master or slave role, device addresses, cable pinout, and application requests before the original module is disconnected.

        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
        What settings must be copied before IC600CB516 is replaced?
        Record both IC600CB516 port modes, baud rates, station roles, device addresses, timeouts, cable pinouts, and every SCREQ block that depends on the module.
        Why can a healthy IC600CB516 still fail to communicate after a swap?
        IC600CB516 communication depends on matching RS-232 or RS-422 wiring, port configuration, device role, protocol timing, grounding, and the application request; the board alone cannot correct a mismatch.
        When should RS-422 be preferred for IC600CB516?
        Use IC600CB516 RS-422 for the supported longer direct-distance or multidrop arrangement, with the verified cable, ground, and termination plan.
        How should an intermittent IC600CB516 link be isolated?
        Check one IC600CB516 port at a time with known settings, inspect connector shielding and grounds, capture error timing, and separate physical-layer faults from SCREQ or host-software issues.
        Can IC600CB516 be replaced with IC600CB536 without review?
        GE lists IC600CB536 as the later substitute for IC600CB516, but the installed port configuration, application requests, rack position, cable pinout, and protocol behavior still require validation.
        What should be backed up besides the PLC program for IC600CB516?
        Keep the IC600CB516 configuration, host or terminal settings, communication scripts, address map, modem parameters, cable drawings, and representative successful message records.
        Why is power-load review relevant to IC600CB516?
        IC600CB516 uses the +5 V, +12 V, and -12 V rack rails. A communication fault can accompany an overloaded or degraded supply, so the complete CPU-rack budget should be checked.
