GE Fanuc IC600CB516 CCM2 Communications Control Module

Product Overview

The GE Fanuc IC600CB516 is a Communications Control Module Type 2 (CCM2) for the Series Six Plus PLC. It gives the controller two serial communications ports for exchanging data with devices such as host computers, graphics terminals and other communications modules. Both ports support RS-232 and RS-422 electrical interfaces.
The CCM2 supports point-to-point and multidrop communications. It can also initiate messages under ladder-logic control through a Serial Communications Request (SCREQ). For applications that need access to PLC data, the module can transfer information from Series Six Plus memory areas including registers and I/O tables. These capabilities make IC600CB516 a communications module—not a field I/O module.
