Message Definitions
A5E0 Fast Operate
Remote Bit Control
The external device sends the following message to perform a remote bit
operation:
The relay performs the specified remote bit operation if the following
conditions are true:
➤ The Operate code is valid.
➤ The Operate validation = 4 • Operate code + 1.
➤ The message checksum is valid.
➤ The FASTOP port setting is set to Y.
➤ 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).
It is common practice to route remote bits to output contacts to provide remote
control of the relay outputs. If you wish to pulse an output contact closed for a
specific duration, SEL recommends using the remote bit pulse command and
SEL
OGIC
®
control equations to provide secure and accurate contact control.
The remote device sends the remote bit pulse command; the relay controls the
timing of the output contact assertion. You can use any remote bit
(RB1–RB16), and any SEL
OGIC control equation timer (SV1–SV16) to
4C Operate code, pulse remote bit RB13
0D Operate code, clear remote bit RB14
2D Operate code, set remote bit RB14
4D Operate code, pulse remote bit RB14
0E Operate code, clear remote bit RB15
2E Operate code, set remote bit RB15
4E Operate code, pulse remote bit RB15
0F Operate code, clear remote bit RB16
2F Operate code, set remote bit RB16
4F Operate code, pulse remote bit RB16
00 Reserved
checksum 1-byte checksum of all preceding bytes
