Description
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
• Frequency: Digital output 41 / 42 as a frequency output. In frequency mode, a frequency is issued that is proportional to
the flow rate.
Selection of submenu '...Puls.Out 41/42' using
Only available if 'Mode' Pulse has been selected.
Selection of submenu '...Freq.Out 41/42' using
Only available if 'Mode' Frequency has been selected.
Selection of submenu '...Binary Out 41/42' using
Only available if 'Mode' Binary has been selected.
Selection of submenu '...Alarm Cfg. 41/42' using
Only available when 'Mode' Binary is selected in the '...Binary Out 41/42 / Signal Source Binary' Alarm menu.
Select process variable that is issued via the pulse output.
Refer to Available process variables on page 98.
Set the pulses per mass unit or volume unit (see table Available units on page 96) for the pulse output.
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
Selection of process variable that is issued via the frequency output.
Refer to Available process variables on page 98.
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.
