m = module number of the proportional pressure regulator
(1 ... 47)
Description
Parameterisation is done via this function number:
Control behaviour (Presets): defines the characteristic curve used for control
ling the set nominal pressure.
Input signal type: defines one of three representation possibilities for the input
word (for the data format see Tab.3/10):
Output of the current pressure value
Output as comparator bit:
Bit 0 = 0: Pressure value is outside the control range
Bit0=1: Pressure v alue is within the control range
Combined output of current pressure value and comparator bit. Bit0 is used
as the comparator bit, as above. It is no longer used for representing the
pressure value.
Measured value smoothing: Sets the level of smoothing of measured values
for limit value monitoring. This can suppress possible spurious values.
Bit
Bit 1, 0: Control behaviour (Presets)
Bit 3, 2: Input signal type
Bit 5, 4: Measured value smoothing
