Hello everyone,

I'm having trouble reading data from a db of the s7-1200, the db is missing the offset column and I can't enable it, I wanted the help of you to set up my industrialcomm node to read this data, follow the prints of what I'm speaking.

In the project tree in TIA Portal, right click on the database DB62 and click properties', untick the optimised block access. Compile your DB and you will have the offset. 😉
