Communication Modules

1746 Communication Modules

In addition to the on-board ports available with SLC processors, you have the option of providing another communication port for an SLC processor by adding a communication module. Each of these modules takes up a single slot in a 1746 chassis local to an SLC processor.

Two of these communication modules only provide an interface between a built-in port on the processor and another communication link with a different type of protocol. The other modules communicate with the SLC processor over the 1746 backplane.

In addition to providing communication ports, the 1746-BAS and 1746-BAS-T modules provide the processing capability to execute programs you generate in the BASIC language. The results from the execution of these programs can be sent out the communication ports or AC ross the backplane to the SLC processor.
