This section explains the outline of the network communications.
The CX-Simulator can debug network communications by: (1) send/receive
FINS commands to the application program (the CPU Unit itself, an applica-
tion program using FinsGateway, or the CPU Unit of FinsGateway) or (2)
screen display of send messages. However, the destination of the FINS
commands is only the CPU Unit itself, an application program using Fins-
Gateway, or the CPU Unit of FinsGateway. Thus debugging network commu-
nications is possible with the CPU Unit itself or the CPU Unit of FinsGateway
as a tentative destination.

Also, receiving FINS commands from an actual external PLC or a computer
connected in the network to the Ladder Engine is possible. (Where sending
by network communications instruction is not possible.)
