●SET / RSET (RESET) Instructions
SET instructions turn and keep a relay coil ON once the input condition is ON.
RSET instructions turn and keep a relay coil OFF.
In the above example, relay coil 000102 is turned ON by the SET condition and OFF
by the RSET condition.
Note Holding areas and auxiliary areas turned ON by SET instructions will retain the ON
status even when power is interrupted or when operation is stopped.
●KEEP(011) (KEEP RELAY) Instructions
KEEP instructions make relay coils function as keep relays. This allows for easy
construction of self-maintaining bits.
In the above example, relay coil 000103 is turned ON by the set condition and OFF
by the reset condition. While the reset input is ON, the set input will be ignored.
Note Holding areas and auxiliary areas turned ON by KEEP instructions will retain the
ON status even when power is interrupted or when operation is stopped.
