• SUBSYSTEM COMMUNICATIONS

The serial communication module communicates with subsystems at the specified intervals and stores the subsystem data in the communication modules’ I/O image area. FCS accesses the communication module asynchronously from them, and refers to or sets the I/O images. This enables FCS to use the subsystem data through the I/O terminals of the function block in the same way as the general analog and digital I/O signals.
