7.2.3. CPU Modules
7.2.3.1. RMC70 CPU Modules Overview
A CPU module contains the processing unit, the communication channel such as serial,
PROFIBUS, Ethernet, etc. and a monitor port or USB port for communications to the RMCTools
software. The CPU module, together with an axis module attached to the front of the CPU
Module, make up a complete motion controller, called a base module. Optional expansion
modules can be added to the right of the motion controller.
The front panel of the CPU contains status LEDs and connectors for power and
communications.

Comparing the RMC75 CPU Modules
In addition to the communication port and RMCTools monitor port, the RMC75 CPUs differ in
the following ways:
• Monitor Port Speeds
The RMC75E USB port provides a much faster connection to RMCTools, with much
faster plot upload speeds, than does the serial port on the RMC75S and RMC75P.
