9.1 PID_Compact
ErrorBits Description
( DW#16#...)
0200 Invalid value at "Input" parameter: Value has an invalid number format.
If automatic mode was active before the error occurred and ActivateRecoverMode = TRUE,
PID_Compact outputs the configured substitute output value. As soon as the error is no longer pending,
PID_Compact switches back to automatic mode.
If pretuning or fine tuning mode was active before the error occurred and ActivateRecoverMode =
TRUE, PID_Compact switches to the operating mode that is saved in the Mode parameter.
0400 Calculation of output value failed. Check the PID parameters.
If automatic mode was active before the error occurred and ActivateRecoverMode = TRUE,
PID_Compact outputs the configured substitute output value. As soon as the error is no longer pending,
PID_Compact switches back to automatic mode.
If pretuning or fine tuning mode was active before the error occurred and ActivateRecoverMode =
TRUE, PID_Compact switches to the operating mode that is saved in the Mode parameter.
0800 Sampling time error: PID_Compact is not called within the sampling time of the cyclic interrupt OB.
If automatic mode was active before the error occurred and ActivateRecoverMode = TRUE,
PID_Compact remains in automatic mode.
If pretuning or fine tuning mode was active before the error occurred and ActivateRecoverMode =
TRUE, PID_Compact switches to the operating mode that is saved in the Mode parameter.
If this error occurred during simulation with PLCSIM, see the notes under Simulating PID_Compact V2
with PLCSIM (Page 95).
1000 Invalid value at "Setpoint" parameter: Value has an invalid number format.
If automatic mode was active before the error occurred and ActivateRecoverMode = TRUE,
PID_Compact outputs the configured substitute output value. As soon as the error is no longer pending,
PID_Compact switches back to automatic mode.
If pretuning or fine tuning mode was active before the error occurred and ActivateRecoverMode =
TRUE, PID_Compact switches to the operating mode that is saved in the Mode parameter.
10000 Invalid value at ManualValue parameter. Value has an invalid number format.
If ActivateRecoverMode = TRUE before an error occurred, PID_Compact uses SubstituteOutput as the
output value. As soon as you specify a valid value in ManualValue, PID_Compact uses it as the output
value.
20000 Invalid value at SubstituteOutput tag. Value has an invalid number format.
PID_Compact uses the output value low limit as the output value.
If automatic mode was active before the error occurred, ActivateRecoverMode = TRUE, and the error is
no longer pending, PID_Compact switches back to automatic mode.
40000 Invalid value at Disturbance parameter. Value has an invalid number format.
If automatic mode was active and ActivateRecoverMode = TRUE before the error occurred, Disturbance
is set to zero. PID_Compact remains in automatic mode.
If pretuning or fine tuning mode was active and ActivateRecoverMode = TRUE before the error oc-
curred, PID_Compact switches to the operating mode saved in the Mode parameter. If Disturbance in
the current phase has no effect on the output value, tuning is not be canceled.
