The CLICK PID Errors are indicated in two places; 1) the PID Monitor Window and 2) register DSn+00.
You may see an error indication on the PID Loop in the PID Loop Monitor selection in the Project tab.
Opening the PID Monitor you will see an Error indicator at the top of the PID Monitor Window.
Clicking on this indicator opens the PIS Monitor Error List.
If there is more than one error, the DS register will contain the lowest active error number. When it is cleared, the next lowest error is indicated.
The most likely cause of errors on a new PID Loop is the PID Loop was configured in the PID Configuration, the program was downloaded to the PLC, but the PID Configuration data was not written to the PLC registers. Open the PID Loop Configuration and select Write Register Values to PLC as a first step to clear errors.
