1. Target
Select the PIDA/PIDD instruction to monitor. All PIDA/PIDD instructions in the ladder program opened in WindLDR are displayed.
The PIDA/PIDD instructions can be identified by the program name and line number in the main program or subroutine where
the instructions are used.
2. Refer to PID settings
Opens a dialog box for the PIDA/PIDD instruction being monitored so that you can confirm the settings.
3. Jump to target PID instruction
Moves the cursor of the ladder editor to the position of the PIDA/PIDD instruction being monitored.
4. Show/hide PID monitor table
You can show or hide PID Monitor Table (11) and Apply Tuned Value button (12).
5. PID monitor settings
Opens the PID Monitor Settings dialog box. For details, see "PID Monitor Settings Dialog Box" on page 19-44.
6. Primary parameters panel
You can check the values of the process variable (PV), set point (SP), and manipulated variable (MV). For the MV, the analog
value can be checked with the horizontal bar graph, and the digital value (on/off) can be checked with the color of the OUT
indicator. When the OUT indicator is white, the output is off. When it is green, the output is on.
The colors of the values for the process variable (PV), set point (SP), and manipulated variable (MV) can be changed in the PID
Monitor Settings dialog box. For details, see "PID Monitor Settings Dialog Box" on page 19-44.
When a PIDA instruction is selected, a digital value (on/off) can be checked with the color of the OUT indicator. The OUT
indicator is white when output is off, and green when output is on.
When a PIDD instruction is selected and manual mode is on, the manipulated variable (MV) text box is enabled, and the manual
output manipulated variable (S1+14, S1+15) can be set. The value can be set between 0.0 and 100.0 in the unit of percentage.
7. PID parameters panel
When a PIDA instruction is selected, you can check the values of the proportional band (P), integral time (I), and derivative time (D).
When a PIDD instruction is selected, you can check the values of the proportional gain (Kp), integral gain (Ki), and derivative
gain (Kd).
