7-2 Connection with Application Programs
7-2-1 Connection Methods
There are two methods for connecting the CX-Simulator with application pro-
grams as follows:
• Coexist in the same com-
puter
An application program using FinsGateway
for communications.
• Connection via network An application program sending/receiving
FINS commands via Ethernet from a real-
time OS, UNIX, or another computer.
Note
1. Always install FinsGateway separately when connecting to applications.
2. All of the above methods assume the connection by polling from an
application program (An application program sends a FINS command
and the Ladder Engine returns a FINS response.). Connection via net-
work is not available for "slave initiation" from the Ladder Engine
(Communications using SEND from a sequence program to an applica-
tion program.).
7-2-2 Coexist in the Same Computer
The following shows a connection method where the CX-Simulator, the
CX-Programmer, and an application program coexist in the same computer.

1. Start the CX-Simulator and select a PLC data folder required in debugging
an application program to display the windows of [CX-Simulator Debug
Console], [System Status], and [Work CX-Simulator].
2. Click the [Connect] button in the [Work CX-Simulator] window.
3. Register the FINS address displayed in the [Guide to Connect] window to
the FINS communications address settings.
