1. The Simulator Communications Unit is the CX-Simulator's own commu-
nications unit supporting only FINS communications. When the Controller
Link Unit or Ethernet Unit is not used, this unit will be used (default).
2. This unit is a virtual unit for maintaining the compatibility with
CS/CJ/CP-series PLCs. No settings are required for this unit.
