FIG 7-26 Process controller
Features
( P adaptation possible via an internal function (derived from set-value) or
external analog signal source; enable adaptation with C329 = -1-

( Overlay of process controller output over ramp function generator
( Intregral action component to be switched-off via freely assignable digital
terminal (I component = 0)
( Deactivation of the process controller via freely assignable digitale terminal (I
component = 0, output = 0)
( Suppression of the process controller output via freely assignable digital
terminal (output = 0 after time C335)
