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.

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.
