A5D2/A5D3 Demand/Peak Demand Fast Meter Message

In response to the A5D2 or A5D3 request, the relay sends the following block:

A5B9 Fast Meter Status Acknowledge Message

In response to the A5B9 request, the relay clears the Fast Meter (message A5D1) Status Byte. The
SEL-351 Status Byte contains one active bit, STSET (bit 4). The bit is set on power up and on
settings changes. If the STSET bit is set, the external device should request the A5C1, A5C2, and
A5C3 messages. The external device can then determine if the scale factors or line configuration
parameters have been modified.

A5CE Fast Operate Configuration Block

In response to the A5CE request, the relay sends the following block:
