If several errors are pending simultaneously, the values of the error codes are displayed with
binary addition. The display of error code 0003, for example, indicates that the errors 0001
and 0002 are pending simultaneously.
0001 The "Input" parameter is outside the process value limits.
• Input > sPid_Cmpt.r_Pv_Hlm or
• Input < sPid_Cmpt.r_Pv_Llm
You cannot move the actuator again until you eliminate the error.
Invalid value at "Input_PER" parameter. Check whether an error is pending at the analog input.
Error during fine tuning. Oscillation of the process value could not be maintained.
Error at start of pretuning. The process value is too close to the setpoint. Start fine tuning.
The setpoint was changed during tuning.
Pretuning is not permitted in automatic mode or during fine tuning.
0080 Error during pretuning. The output value limits are not configured correctly or the actual value does not
react as expected.
Check whether the limits of the output value are configured correctly and match the control logic.
Also make sure that the actual value does not oscillate strongly before starting pretuning.
Error during tuning resulted in invalid parameters.
Invalid value at "Input" parameter: Value has an invalid number format.
Calculation of output value failed. Check the PID parameters.
0800 Sampling time error: PID_Compact is not called within the sampling time of the cyclic interrupt OB.
If this error occurred during simulation with PLCSIM, see the notes under Simulating PID_Compact V1
Invalid value at "Setpoint" parameter: Value has an invalid number format.
