If there are no requests being sent, your software is improperly configured, and check that there were no errors on startup of CitectSCADA. If there were errors on startup, look them up in the Help.

If there are requests, you can see communications between CitectSCADA and Winsock in a separate window, which displays the requests made by CitectSCADA to connect to the I/O Device and the corresponding response from the I/O Device.
