Are you on the same network as the PLC?

Check your firewall settings

When you look at the diagnostics in the S7A powertool are you getting all errors?

Yes you have to fill your I\O addr column.

Example PLC : DB1.DBW 1 where PLC is the name of the device in the S7A Powertool and DB1.DBW 1 is the address of your tag in the PLC. (No spaces between PLC and : or between : and address)

Have you added the driver listed in the SCU?

Have you followed the setup instructions in the S7A help file?

Can you post a screenshot of the S7A configuration, your ifix database and the setup of your PLC CP?

What is the IP address of your iFix station? Can you ping the PLC?

What do you see when you click on diagnostics for each of the PLC's as circled?

Are you PLC's enabled?

Can you go online to the PLC using Simatic Manager from the ifix station?
