Description
Input/Output /
...Dig.Out 41/42
Mode
Selection of the operating mode for the digital output 41
/ 42.
•
Off: Digital output 41 / 42 deactivated.
•
Binary: Digital output 41 / 42 as a binary output (e.g. as an alarm output).
•
Pulse: Digital output 41 / 42 as a pulse output. In pulse mode, pulses per unit are output (e.g. 1 pulse per m
3
).
•
Frequency: Digital output 41 / 42 as a frequency output. In frequency mode, a frequency is issued that is proportional to
the flow rate.

Signal Source Pulse
Select process variable that is
issued via the pulse output.
Refer to Available process variables on page 98.
Quantity Pulses
Set the pulses per mass unit or volume unit (see table
Available units on page 96) for the pulse output.
Quantity Mass
Quantity Volume@
Pulse Width
Set the pulse width (low signal) for the pulse output.
The parameter directly limits the maximum possible output rate
of pulses, for example max. 500 pulses/sec at 1 ms. If the
calculation of the current output rate leads to an up
-scale, the pulses are buffered and output with a delay.
Setting range: 0.05 to 2000 ms
Input/Output / ...Dig.Out 41/42 / ...Freq.Out 41/42
Signal Source Freq.
Selection of process variable that is issued via the frequency output.
Refer to
Available process variables on page 98.
Upper Range Value
Set the frequency range for output of the selected process
variables.
•
Upper Range Value: Set the frequency for 100 % of the process variable.
• Lower Range Value: Set the frequency for 0 % of the process variable.
Lower Range Value
