Remote Bit Application Ideas
With SELOGIC 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.
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.
