We have PI OPC DA tags for which there is a spike in data at random timestamps.Can anyone advise us if we can change settings in OPC interface to avoid spikes in data
This is a bit of an odd question. Typically you want PI to store the data you get, and receiving / measuring spikes is valuable data if this is true.
However if you are convinced the spikes do not match reality, one option to deal with these is to set the zero and span of the pi point to a value lower than the spike value. Then all values outside of the bandwidth created by zero and span should be marked as incorrect data in PI.
