Description
Selection of the operating mode for digital output V1 / V2.
Digital output V1 / V2 is only available if the corresponding plug-in card is present!
• Off: Digital output V1 / V2 deactivated.
• Logic: Digital output V1 / V2 as a binary output (for example, as an alarm output).
Selection of the operating mode for digital output V3 / V4.
Digital output V3 / V4 is only available if the corresponding plug-in card is present!
• Off: Digital output V3 / V4 deactivated.
• Logic: Digital output V3 / V4 as a binary output (for example, as an alarm output).
The operating modes are available with an APO card only. When these operating modes are selected, DO51 / 52 is mirrored
to V3 / V4.
• Frequency: Digital output V3 / V4 as a frequency output. In frequency mode, a frequency is issued that is proportional to
the flow rate. The maximum frequency can be configured in accordance with the upper range value.
• Follow DO 41/42: Digital output V3 / V4 follows the function of digital output 41 / 42. Depending on the setting of the
'Input/Output / ...Dig.Out 41/42 / Outp. Flow Direction' parameter, digital output V3 / V4 is operated in pulse mode as
follows:
– No pulses are issued if 'Forward & Reverse' is selected. Only digital output 41 / 42 is active.
– When 'Forward' is selected, pulses for forward flow are output on digital output 41 / 42, while pulses for reverse flow
are output on digital output V3 / V4.
– When 'Reverse' is selected, pulses for reverse flow are output on digital output 41 / 42, while pulses for forward flow
are output on digital output V3 / V4.
• 90° Shift: Output of the same pulses as for digital output 41 / 42, phase shifted by 90°. Only if digital output 41 / 42 has
been configured as a pulse or frequency output.
• 180° Shift: Output of the same pulses as for digital output 41 / 42, phase shifted by 180°. Only if digital output 41 / 42 has
been configured as a pulse or frequency output.
• Follow DO 41/42 (Frequency): Digital output V3 / V4 follows digital output 41 / 42. Digital output V3 / V4 then also works
as a frequency output, the settings under '... / Dig.Out 41 / 42 / ...Setup Freq Output' are accepted.
The output of the frequency at digital output V3 / V4 is dependent on the setting of the register 'Outp. Flow Direction' for
digital output 41 / 42:
– When 'Forward' is selected, a frequency for forward flow is output at digital output 41 / 42 and a frequency for reverse
flow is output at digital output V3 / V4
– When 'Reverse' is selected, a frequency for reverse flow is output at digital output 41 / 42 and a frequency for forward
flow is output at digital output V3 / V4
• 180° Shift (Frequency): Output of the same frequency as for digital output 41 / 42, phase shifted by 180°
Note
Digital output V3 / V4 cannot be configured as an additional independent frequency output (operating mode 'Frequency
(=51 / 52)'. Digital output V3 / V4 can be configured separately as a binary or frequency output.
However, digital output V3 / V4 cannot be configured as a second independent pulse output.
