Control Equations & Relay Logic
B.16.1 Remote Bit Application
Ideas
With control equations, you can use the remote
bits to trip or start the motor or to open, close, or
pulse relay output contacts for other purposes.
Also, you can use remote bits like a contact input
in operating latch control switches. Pulse
(momentarily operate) the remote bits for this
application.
B.16.2 Remote Bit States Are Not
Retained When Power Is
Lost
The states of the remote bits (Relay Word bits
RB1 – RB4) are not retained if power to the relay
is lost and then restored. The remote control
switches always come back in the OFF position
(corresponding remote bit is deasserted to
logical 0) when power is restored to the relay.
