This is a version of the Comm Logic board for the Data Hiway Port.

This version of the Comm Logic board must only be used with the 30751044-006 or 30751044-008 ROM board.

The Comm Logic board contains a microprocessor, RAM memory, and other circuitry necessary to communicate with the PLC network connected to the DHP. The Comm Logic board performs the function of translating a given PLC protocol into the protocol required to communicate with Hiway preferred devices.
