DNP 3.0 timing considerations

Table 11: The IED's worst-case error over the full operating temperature range
Description
Time base drift over a 10-minute interval
Maximum delay measurement error
Maximum internal time reference error when set
from the protocol
Maximum response time
Event time accuracy
Event processing delay
1) This represents the time it takes for a physical input from the time it changes to the time it is reported
by DNP 3.0. The internal latency between the protection logic and the communication processor is 4
ms for BI, and 500 ms for AI.
Data link layer filtering is not performed based on the source address.
