Message Definitions
A5E0 Fast Operate
Remote Bit Control
The external device sends the message shown in Tabl e D.9 to perform a
remote bit operation.
The relay performs the specified remote bit operation if the following
conditions are true:
1. The Operate code is valid.
2. The Operate validation = 1 + (Operate code • 4).
3. The message checksum is valid.
4. The FASTOP port setting is set to Y.
5. The relay is enabled.
Remote bit set and clear operations are latched by the relay. Remote bit pulse
operations assert the remote bit for one processing interval (1/4 cycle).
