6-1 Outline of Network Communications

Introduction
136
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 application
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 FinsGateway, or the
CPU Unit of FinsGateway. Thus debugging network communications is pos-
sible 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.)
