The input setpoint nNSet_a is output
without any changes at the output
nOut_a.
1 nNSet + nNSet_PID
nNSet_a and nAct_a are used as PID
input values. The arriving nNSet_a is
additively linked to the value output
by the PID element.
2 nSet_PID
nSet_a and nAct_a are used as PID
input values. The input nNSet_a is
not considered.
3 nNSet_PID
nNSet_a and nAct_a are used as PID
input values. The input nSet_a is not
considered.
4 nNSet + nSet_PID
nSet_a and nAct_a are used as PID
input values. The arriving nNSet_a
setpoint is additively linked to the
value output by the PID element.
5 nNSet || nSet_PID
nSet_a and nAct_a are used as PID
input values. The setpoint nNSet_a is
output at the output nOut_a . The
PID output value is output at the
output nPIDOut_a.
