9 COMMUNICATION BETWEEN THE MASTER STATION AND REMOTE I/O
STATIONS
This chapter explains the procedures from module settings to parameter settings,
programming, and finally operation check using a system configuration example.
9.1 Configuring a System
As shown below, a system with three connected remote I/O stations is used as an
example.
