Hello,
i use the S71500 driver to get tags from a PLC.
I use a UDT to create several instances wich then refer to different DBs in the PLC.
For some reason, DB 11106 is not readable.
Only data from DB11105 is readable, 11106 throws a “config error” even though they are configurated identically.
Here you can see that both tags use the same UDT:
This is the item path, instead of 11105 there is 11106 in the other tag.
But only one of the tags is able to read data from the PLC:
Both datablocks are available in the plc, they are configured identically:
Can anyone please tell me what im doing wrong here?
