Implementation
The following diagram shows the electrical control connections of a single-axis hydraulic system
using RMC-DI/O in Input to Event Mode (the PC and its RS232 cable are needed only during
setup):
This document discusses only the connections between the Programmable Controller and the
RMC. For details on the transducer and drive wiring, look up Wiring Notes in the RMCWin index.
Input to Event mode requires use of the Event Control feature of the RMC. You should first
familiarize yourself with Event Control and the Event Step table. The RMCWin online help is a
