The CX-Simulator supports only FINS communications for network communi-
cations and does not support the other communications (e.g. socket commu-
nications of the Ethernet Unit). The following virtual Network Communications

1. The Simulator Communications Unit is the CX-Simulator's own commu-
Note
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-
series PLCs. No settings are required for this unit.
The instruction words related to serial communications that can be used in a
program are shown below.
