Basic System Description
The Option Board connects to the Master via a DeviceNet network cable.
Inverter I/O data is generally shared with the Master's I/O memory through the
DeviceNet network. Every DeviceNet communication cycle, Inverter I/O data
is collected by the Option Board and exchanged with the Master. The PC (per-
sonal computer) allows you to configure, monitor, program, diagnose and
operate the system.
