We have an iFix scada using a Kepware BSAP driver to talk to a Bristol Babcock ControlWave PLC. Values take ~11 min to update. Scan times in iFix and Kepware are 5 sec or less. I created a test OPC item in the Kepware OPC Quick Client with a scan rate of 250 msec and also takes 11 min to update. I'm leaning toward something in the PLC that would cause this delay in communication, however I am not at all familiar with what settings in a ControlWave might cause this.
Any help would be appreciated.
