Pulse counting from a water meter would use a single edge trigger, depending on the
resting state of the connected device (positive pulse would use rising edge, negative
pulse would use falling edge).
3.4.2.2
Count Threshold
The Count Threshold determines when the Sensor transmits after seeing an event on the Digital
Input. A value of 0 (zero) disables the event driven transmission, while a value of 1 (one) or
greater triggers an event-based transmission after the configured number of events has
occurred.
Application Example:
•
If a sensor is intended to pulse count from a high-volume water meter, it may be
configured to disable event-based transmission in favor of getting hourly reports from
the sensor.
•
If a sensor is intended to monitor room utilization it may be configured to only transmit
after 100 ‘events’ logged in the room. This may be useful for alerting cleaning staff that
room requires attention.
3.4.2.3
Value to Tx
The Value to Tx determines what information is transmitted whenever an event or periodic
digital transmission is required.
If the value is ‘
Counter Value
’, the transmission
contains the
number of times the Digital Input was triggered since the last transmission, while the value of
‘
Input State
’ causes a t
ransmission of the current input state of the switch (i.e. Open or Closed).
