We run Citects OPC-client and tries to communicate with the Fieldpoint OPC-server. Analog values AI/AO work all fine but DIO-550 I/O-values do not. The data type is VT_BOOL. The error message is "Bad value". The client can be configured to skip "bad value"-error. That solves DO but not DI.
Testing Macs OPC-client gives same problem.
Our Fieldpoint OPC-server works fine with NI Server Explorer and the Citect and Macs clients works fine with other OPC-servers!
Please someone give us a hint of what to do.
