SEL-587Z Instruction Manual
Serial Port Communications
SEL Binary Protocols, Fast Meter, and Fast Operate
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-587Z 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.
Fast Operate
