Appendix F
Control Networks
This appendix provides a brief introduction about control networks.
For more information on using control networks, see the following
publications.
The Allen-Bradley Remote I/O Network is a master/slave control
network that enables chassis of I/O, operator interface terminals,
push-button panels, I/O blocks, message displays, and drives to be
great distances from the host PLC processor. The SLC 500 fixed,
SLC 5/01, SLC 5/02, SLC 5/03, SLC 5/04, or SLC 5/05 processors can
interface to this network through the 1747-DCM module for
distributed control. The DCM lets the SLC 500 processor look like
another slave device on the network.
