6.10 Setting of Output (Y) Status when Changing between STOP and

RUN

(1) Definition

When changed from the RUN 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.

Status when changing from STOP to RUN can be selected from the following two

options with parameters in GX Developer.

• The output (Y) status prior to STOP is output.

• The output (Y) 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
