After updating to version 7.9.5 the value of a memory tag which belongs to a UDT is continually being overriden by the system, although we disable the override by unclicking the green circle, this is automatically clicked by the system few minutes later.
If we create a UDT instance from the scratch we don’t have this problem, but we can’t do this for all the existing instances, over one thousand, with lots of variables which are currently being historized, the project scope consists of the migration of an old SCADA system for one of our most important customers in the pharmaceutical industry and besides the huge amount of time that we would need to create all the instances again we must guarantee the congruence of all the data stored so far, what would mean a lot of database rework too.
I wonder if it is possible to downgrade to version 7.9.3 as long as we have the guarantee that this is going to solve the problem.
