The display for Segment Program 2 (157) is shown below.
It is possible to automatically calculate and store the PID constants used for
Basic PID (011) or Advanced PID (012). This function is called auto-tuning
(AT). For details of the AT function, refer to the section on Basic PID (011) in
the Loop Control Unit Function Block Reference Manual. AT can be set in the
same way as the other settings, as shown below.
1. If the value for AT displayed in the upper-left region of the Tuning Screen is
0, then AT will not be executed.
2. Click AT.
The Change Data Dialog Box shown below will be displayed.
3. To execute AT, input 1 in the New Data Field.
4. Click the OK Button. AT will be executed (see note). The value for AT dis-
played in the upper-left region of the Tuning Screen will change to 1.
5. When the PID constants have been calculated and stored and AT has been
completed, the value for AT displayed in the upper-left region of the Tuning
Screen will return to 0.
Step settings can be changed by clicking on the word.
