2-2-1 Overview
To use the CX-Integrator, the computer must first connect online to a PLC connected
though a direct serial connection or another PLC in the network (known as the relay

be specified as the target PLC and accessed through the relay PLC.
Normally, the same PLC is both the relay PLC and the target PLC.
