This OPC UA Property, of type UInt32, is the TimeDelay parameter for the object’s event algorithm. It represents the time, in seconds, that the offnormal conditions must exist before an offnormal event state is indicated.

It is normally used to represent the BACnet property Time_Delay.

This OPC UA Property, of type UInt32, is the TimeDelayNormal parameter for the object’s event algorithm. It represents the time, in seconds, that the normal conditions must exist before a NORMAL event state is indicated.

It is normally used to represent the BACnet property Time_Delay_Normal. If the BACnet property Time_Delay_Normal is not present it has the same value as the BACnet property Time_Delay.
