Looking at the change of state subscription interface there's no explanation or way to modify the Duration parameter which defaults to one second. This is used in OPC UA as a minimum reporting time so will never report back faster than 1 second.
What's everyone's thoughts on adding this as an optional parameter? I thought about changing the default but I think 1 second is a good value for it. I also think an absolute minimum value should be allowed of 5 or 10ms. * Adds a new field to the to be constructed request which should be updated as soon as * a value changes in the PLC. * * @param name alias of the field. * @param fieldQuery field query string for accessing the field. * @return builder. */ PlcSubscriptionRequest.Builder addChangeOfStateField(String name, String fieldQuery);
