Communications Choices
The versatile RMC100 Motion Controllers can be configured with one of five
different communication modules supporting more than 25 protocols. The bus-
based communication modules are not just for motion data acquisition—they
support full motion control via the host system. (RMC100 motion controllers also
have an RS232 serial port for use with Delta’s RMCWin setup, tuning and
diagnostics package.) Your choice of a Comm Module will depend on the required
performance and compatibility match with your communication architecture.

A short description of each communication module follows. The RMC part number
designation of each module is in parentheses.
Ethernet (-ENET)
The RMC100 offers a communication module for EtherNet/IP. This protocol is an
open protocol that has steadily been gaining popularity in the industrial world.
EtherNet/IP is innovative in that it combines the traditional messaging services with
higher-performance and more deterministic I/O services. The RMC ENET supports
both EtherNet/IP messaging and I/O. The Ethermet module can be used to
communicate with RMCWin.
