Hi.
We recently got our ignition connected to the S7-1200 PLC, but any and all tags added to ignition get
“[CONFIG_ERROR] null”
PUT/GET is enabled in the plc.
I have added tags like DB44,X122.0 which is a boolean in DB44, just to test, it gets last value “n/a”, and quality is empty.
How to gain access to the tags, any ideas?
EDIT: Now when i checked wrapper.log i find this:
