I am using Citect SCADA reading GE PQM memory map through Modbus protocol. I can not have the right value from an Unsigned Long Integer data type(Energy used). Is anybody out there who has had the same problem?.

Thanks,
Eduardo

 

Have not used the PQM but have used the SR489 extensively. Would imagine that GE would be consistent through their range. Have not had any problems with the SR489.
