Ramp function
This function creates a ramp-like setpoint curve out of a step-like setpoint curve, where the ris-
ing and falling edges can have different gradients.
Tolerance band function
In the case of a program controller and ramp function, a tolerance band can be set around the
setpoint value curve in order to monitor the actual value. If the upper or lower limits are exceed-
ed, a tolerance band signal is triggered, which can be processed further internally or issued via
an output.
Signal for ramp off No selection The ramp can be switched off with this
signal.
With a binary signal, the ramp end value
is applied only once (in the case of a ris-
ing edge) as the current controller set-
point value in the form of a step without a
ramp.If the ramp end value is changed
again, this behavior is no longer active
and the ramp end value is approached
again as a ramp with the specified gradi-
ent.
