>Impulse counter<
The system counts and saves the number of oncoming signals on the digital input.
The impulses are counted by detecting the status change of the digital input (1->0 or
0->1).
ƒ
Selection/Input Options:
Edge: >rising< (status change “0” to “1”) or >falling< (status change “1” to “0”)
Label: manual input
• >Logging<
Logging of readings and the according status changes for diagnostic purposes.
Evaluation is carried out by detecting the status changes of the digital input (1->0 or
0->1).
ƒ
Selection/Input Options:
Logic: >not inverted< or >inverted<
Label: manual input
32.5.4 Digital Outputs
The number of digital outputs depends on the type (see Sect. “17.1 Device Types”).

• >Sum impulses<
Output of volume-proportional sum impulses.
ƒ
Selection/Input Options:
Logic: >Normally open< or >Normally closed<
Negative sum impulses: check box
Quantity: manual input
Duration: manual input
• >Limit contact flow<
If the entered upper flow limit value is exceeded, a digital signal is output. If the value
falls below the lower flow limit, this digital signal is reset = hysteresis function to avoid
output jitter.
