6.4 Setting of Output (Y) Status when Changing between STOP and
RUN
(1) Definition
When changed from the RUN or other status to the STOP status, the CPU module
stores the output (Y) in the RUN status into the PLC and turns all outputs (Y) OFF.
The status after transition from STOP to RUN can be selected from the following two
options with the CPU module.
• The output (Y) status prior to STOP is output.
• The output is cleared.
(2) Setting applications
Using a holding circuit or similar, it is possible to select whether the output is resumed
from the previous status or not when the STOP status is changed to the RUN status.
• When the output (Y) status prior to STOP is set to output
• When output (Y) is set to clear
