Change events in the IED are generated by the device's internal event system; they are not polled at a protocol-
specific scan rate. The periodicity for each point depends on the point's data rate in the IED.
Binary change event scan period – see above
Double bit change event scan period – see above
Analog change event scan period – see above
Counter change event scan period – see above
