Table 1-4 Control technical function of the inputs FE1 to FE3
Function inputs FE4 to FE12 have the following control-technical function:
FE4 disturbance variable connection (z) for the D-element or for the manipulated variable
y (selection by S55)
FE5 Follow-up input (y
and in S-controllers with external follow-up (S2 = 2)
FE6 Manipulated variable feedback supply (y
nal feedback (S2 = 1) or the manipulated variable feedback input (y
lers with external feedback (S2 = 2); Process display (S1 = 9) with XIII
FE7 Manipulated variable connection (z) selection S57
FE8 External setpoint
FE9 Follow-up input y
FE10 Manipulated variable feedback supply y
FE11 manipulated variable connection setpoint
The function inputs FE1 to FE3 have different control-technical functions depending on the
controller type (S1).
