Direct Communication Module

The 1747-DCM module links the SLC 500 controller to the Allen-Bradley PLC for

distributed processing. The DCM acts as a remote I/O adapter on a remote I/O link.

Information is transferred between a local PLC or SLC scanner and a remote

1747-DCM module during each remote I/O scan. The number of DCMs that a scanner

can supervise depends on the number of chassis the scanner supports and the chassis size

of the DCM. The SLC 500 module controllers support multiple DCMs.

Note: An important distinction between a DCM module and the 1747-ASB module is

that a DCM is placed in the chassis with the processor and it does not scan any I/O in the

chassis as an ASB module does.

Ethernet Network

The TCP/IP Ethernet network is a local-area network designed for the high-speed exchange of information 

between computers and related devices. With its high bandwidth (10 Mbps to 100 Mbps), 

an Ethernet network allows many computers, controllers, and other devices to communicate over vast distances. An Ethernet network

The 1747-BSN module contains the full complement of RIO scanner features, plus

backup capability for support of redundant processor applications. The backup system

consists of one or more pairs of complementary modules, with one module residing in the

primary system and the other in the backup system. The primary system controls the

operation of remote I/O, while the backup system monitors communications via the

high-speed serial link (HSSL) and is available to take control in the event of a fault in the primary system.
