10.2 PID control
S7-1200 Programmable controller
598 System Manual, V4.2, 09/2016, A5E02486680-AK
10000 Invalid value at the ManualValue parameter: Value has an invalid number
format.
Note: If ActivateRecoverMode = TRUE before the error occurred,
PID_Compact uses SubstituteOutput as the output value. As soon as you
assign a valid value in the ManualValue parameter, PID_Compact uses it as
the output value.
20000 Invalid value at the SubstituteValue tag: Value has an invalid number for-
mat.
PID_Compact uses the output value low limit as the output value.
Note: If automatic mode was active before the error occurred, Acti-
vateRecoverMode = TRUE, and the error is no longer pending,
PID_Compact switches back to automatic mode.
40000 Invalid value at the Disturbance parameter: Value has an invalid number
format.
Note: If automatic mode was active and ActivateRecoverMode = FALSE
before the error occurred, Disturbance is set to zero. PID_Compact remains
in automatic mode.
Note: If pre-tuning or fine tuning mode was ac
tive and ActivateRecoverMode
= TRUE before the error occurred, PID_Compact switches to the operating
mode that is saved in the Mode parameter. If Disturbance in the current
phase has no effect on the output value, tuning is not canceled.
Note: If automatic mode was active before the error occurred and ActivateRecoverMode = TRUE,
PID_Compact remains in automatic mode.
Note: If pre-tuning or fine tuning mode was active before the error occurred and ActivateRecover-
Mode = TRUE, PID_Compact switches to the operating mode that is saved in the
Mode parameter.
Note: 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.
Note: If ActivateRecoverMode = TRUE before the error occurred, PID_Compact cancels the tuning
and switches to the operating mode that is saved in the Mode parameter.
