  ○ Always
  ○ When reporting event data (slave devices only)
  ○ When sending multi-fragment responses (slave devices only)
  ○ Sometimes
  ● Configurable as: "Only when reporting event data", or "When reporting event data or multi-fragment messages."

Others: • Transmission delay, configurable (tRxToTxMinDel for each channel).
• Select/Operate arm timeout, configurable (tSelectTimeout for each master session).
• Need time interval, configurable (tSynchTimeout for each master session).
• Unsolicited notification delay, configurable (tUREvBufTout1, tUREvBufTout2, tUREvBufTout3 for each master
session).
• Unsolicited response retry delay, configurable (tURRetryDelay for each master session).
• Unsolicited offline iInterval, configurable (tUROfflRtryDel for each master session).
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
