Data type
Value/meaning
nOut_a
INT
Output signal
• Internal limitation to ±32767 (±199.99 %)
• Scaling: 16384 ≡ 100 %
bSetEqAct
INT
Status output "Setpoint and actual value are identical"
TRUE Setpoint and actual value are identical, i.e. no system deviation
available.
nPIDOut1_a
INT
PID controller output without influencing factor nInfluence_a
• Inputs bEnableInfluenceRamp and nInfluence_a do not have any effect here, the
limited PID output value influenced by the internal ramp times is output.
• There is no connection with the additive input nNSet_a.
• Scaling: 16384 ≡ 100 %
nPIDOut2_a
INT
PID controller output with influencing factor nInfluence_a.
• There is no connection with the additive input nNSet_a.
• Scaling: 16384 ≡ 100 %
• Display parameter: C00245
nInfluenceOut_a
INT
Current influencing factor ("ramp status") on the PID output value
• Scaling: 16384 ≡ 100 %
