Examples of Program Control Progress
Example 1: Terminate Program Control when Program Ends
The following diagram shows an example of the program control when terminate program control is
selected as the program end action.
Time of steps: Step 0 and 1: 60 minutes, Step 2: 30 minutes, Steps 3 to 9: 0 minute
In this example, D1000 is allocated to the control register and M500 is allocated to control relay.
Note: The PID module executes all steps 0 to 9 even if the step times of steps are zero. When the program control is
terminated, nine is stored in the current step number of block 0.

The program control is started
from the start of Step 1. The program control is held at the
40 minutes of remaining time.
The program control is proceeded to
the start of step 1 while the program
hold is maintained.
The program control is proceeded to
the start of step 2 while the program
hold is maintained.
15 sec 45 min 30 sec 30 min 20 min 30 min 5 min
The program hold is canceled, and
the program control is started from
the start of step 2.
