PS 10.1 PS-OPC connection, send negative INT values




I discovered a strange behavour in communication between PS and PLC. 

I have defined an INT signal in PS connected with an INT input variable inside the PLC.

When I send a positive value to the PLC everything is ok. When the value becomes negative an errore occurs related to the address in the OPC.

Using OPC scout to send a negative value to the same PLC input works perfeclty, so the problem should be related to PS-OPC communication.


Did someone experiment the same problem?
