    The problem is solved. After thinking for a while I managed to solve a problem with a help from my colleagues.I was using Sharp7 to write into DB, then clone some of the variables to another DB and then read them, so that I can check if everything works fine.

Doing that I encountered some strange problems which most probably aren't caused by the Sharp7, but I guess that someone here will be able to help. Let me start with the first one... On the PLC I have a DB that looks like: If I read the DB using the Sharp7 I get: All the variables are...
