9.9 Setting Starting time of program operation
Description
The starting time of program operation refers to the time from the start of the program
operation (RUN) to the start of the program pattern. The starting time of the program
operation (S.TM) can be delayed by the set amount of time. The time that is counted is
the time from the time when the operation mode is changed from non-program operation
to program operation up to the start of operation. The count-down time can be checked
in Remaining Segment-time Display (Operation Display).
State until program operation starts
Target setpoint Action according to the final target setpoint before the operation mode is
changed
PV event Off
Time event Off
Status lamp PRG lamp is lit
When the delay action up until program operations starts is cancelled, the operation
mode is changed to other than program operation. For example, when local operation
is switched to program operation and then the operation mode is switched to local
operation during the delay action, the state returns to the local operation state.
The following figure shows an example of changing local operation to program operation.
