1747-DCM
The Direct Communication Module, Catalog Number 1747–DCM, is used to connect an SLC 500 Fixed Programmable Controller with expansion chassis or any SLC 500 Modular Programmable Controller to a supervisory Allen–Bradley Programmable Controller via the RIO Link, thereby providing a distributed processing system. The DCM occupies one slot in any SLC 500 chassis.
The Direct Communication Module is an SLC 500 family Remote I/O (RIO) adapter. It allows supervisory processors, such as PLC–5s, and distributed SLC–500 processors residing on an Allen–Bradley RIO Communication Link to transfer data between each other. The DCM appears as an RIO adapter to: • a PLC processor with integral RIO scanner on the RIO Communication Link • an RIO scanner, Catalog Number 1771–SN or 1747–SN, on the RIO Communication Link
Information is transferred between the RIO scanner and the DCM every RIO scan. RIO transmissions are asynchronous to the processor scans. Important: The DCM provides word integrity on all words transferred via the SLC backplane. The DCM communicates with supervisory PLC or SLC controllers through RIO scanners, as if they were addressing a logical rack. However, the DCM does not scan the I/O in its local I/O chassis, rather it passes the supervisory data to the distributed SLC processor.
In the DCM, outputs from the SLC output image table are inputs to the supervisory processor input image table. Likewise, outputs from the supervisory processor output image table are inputs to the SLC input image table. The diagram that follows depicts the communications flow between an RIO scanner and the DCM.
