PCo TagStoreQuery setting junk characters.

Hi all,

In MII, i am using TagStoreQuery to set a value to a PLC tag [Matrikon Simulator]. When the MII Transaction is executed PLC tag has a junk value and not the text we set.

Ex: j?Z? , ?? , |  ....

This was working till yesterday and since this morning its not working. We haven't made any changes.

Version:

MII: 14.0.5.8

PCo: 2.3

OPC/PLC Simulator: Matrikon

Any help would be highly appreciated.

Thanks,

Shridhar..
