Hello:
I'm developing an application based on Monitor Pro V7.0 (USDATA Factory Link) and Momentum Ethernet PLC's. I'm using OPC (OFS driver V2.5).
Does anyone know if there is any possibility to read 32 discrete inputs from Momentum in a lonely UDINT variable just for decreasing communication tag number?
We've already tried and it works properly except but We have a problem with the msb bit. If this bit is "1", it means the rest of bits from this variable change all its values, of course it's an effect of two's complement conversion, just
because the OFS or MPRO always works with signed variables. Is it possible working with unsigned long integer variables (32 bit) in OFS and MPRO7 ?
Did someone achieve this effect with good results?
Thanks for the replies.
