Outputs
bLoadIntValue
BOOL
Loading of the integrator
• Display parameter: C04389/2
TRUE Set the integral action component of the PID controller to the value
applied to the input dnIntValue_n.
dnIntValue_n
DINT
Scaled value on which the integral action component of the PID controller is adjus-
ted by setting bLoadIntValue to TRUE.
• Scaling: 100 % ≡ 2
30
≡ 1073741824
• Display parameter: C04388/3
bReset
BOOL
Reset PID controller to zero
• Display parameter: C04389/3
FALSE PID controller is activated.
TRUE PID controller is reset to zero.
dnAdaptGain_n
DINT
Scaled value for adapting the controller gain
•The dnAdaptGain_n input value is first evaluated via a parameterisable characte-
ristic function and then adapted to the controller gain (C04378).
• In the characteristic default setting (y = 100 %), dnAdaptGain_n is ineffective. The
controller gain is directly effective (C04378).
• Scaling: 100 % ≡ 2
30
≡ 1073741824
• Display parameter: C04388/4
dnInfluence_n
DINT
Scaled value for evaluating the dnOut_n output signal
•The evaluated dnOut_n output signal is output at dnOutRed_n.
• Scaling: 100 % ≡ 2
30
≡ 1073741824
• Display parameter: C04388/5
Identifier/data type Value/meaning
dnOut_n
DINT
Output signal
• Is internally limited to the limit range parameterised in C04381 and C04382 (de-
fault setting ±200 %).
• Scaling: 100 % ≡ 2
30
≡ 1073741824
• Display parameter: C04388/6
dnOutRed_n
DINT
Output signal evaluated via dnInfluence_n input signal
• Scaling: 100 % ≡ 2
30
≡ 1073741824
• Display parameter: C04388/7
dnActSetValue_n
DINT
Current setpoint of the ramp function generator
• Scaling: 100 % ≡ 2
30
≡ 1073741824
• Display parameter: C04388/8
dnDeviation_n
DINT
System deviation
• Scaling: 100 % ≡ 2
30
≡ 1073741824
• Display parameter: C04388/9
bLimitActive
BOOL
Status signal "Limitation active"
• Display parameter: C04389/4
TRUE The output signal is limited.
