Hi, sorry to hijack your old post.
I have downloaded ASComm Excel Add-in and trying to read from an S7-1200 CPU.
I keep getting errors. The help file doesn't explain in enough detail how to setup the software, anyone have any experience using this?
The error I am seeing is 'Invalid. Object reference not set to an instance of an object'.
All i'm trying to do is read MB100 as a test on an IP of 192.168.0.1 on a S7-1214C CPU. Can go online without issue using TIA.
