• When this setting is set at “7”, the operation mode is changed to the READY
mode if the internal contact is changed from OFF to ON, and the operation mode
is changed to the RUN mode if the internal contact is changed from ON to OFF.
• When this setting is set at “19”, the SOAK is moved to the top of the next RAMP
or the RAMP is moved to the next RAMP if the internal contact is changed from
OFF to ON in the RUN mode. This operation is called “advance”.
When the advance operation is performed in the SOAK of the final step, the
operation mode is changed to the READY mode, the operation is moved to the
top of the RAMP of step 1 by loop, or the SOAK is continued according to the
setting of [
C35
: Step operation loop].
• When this setting is set at “20”, the progress of the step operation is stopped if the
internal contact becomes ON in the RUN mode. This operation status is called
“step hold status”. When the advance operation is performed in the step hold
status, the operation enters the step hold status at the top of the next RAMP or
SOAK.
