Set Reset
Description
When the set input turns on, output of the specified relay goes on and stays on.
Output relay goes off when the reset input turns on.
The output relay's on state is maintained until a reset input turns on, regardless of the on or off states of the set
input.
If the set input and reset input turn on simultaneously, the reset input has priority.
Precautions during programming
When the KP instruction is programmed between the MC and MCE instructions, the status of output
destination (relay) specified by the KP instruction is maintained.
If a internal relay (R) specified by the KP instruction is set as the non-hold type, it is reset when the mode of
operation is changed from RUN to PROG or when the power is turned off.
(If an internal relay set as a hold type is specified as the output destination, a reset does not take place.)
