Function
• The counter increments on a change in the value from 0 to 1 (rising edge).
• The counter counts upward from 0 to an adjustable threshold. If it reaches this threshold, the counter
stops and the Overflow output receives a value 1 (true) on the next rising edge.
• Reset input:
o Value 0: The counter runs upwards.
o Value 1: Resets the counter to 0 and disables it. The output value is 0.
• Threshold input:
o Defines the counter threshold.
o Can only be entered if the Output value is connected.
Bus voltage failure, download and restart
The counter value is saved. The output value is restored on restart. The output value is updated the first
time the counter value changes after restart.
Application examples
• Telegram counter: counts the number of telegrams received (usage of Telegram received used on the
KNX input).
