6.1.1.3 Using DI1 as counting input
General information on use as a counting input
The counting input is used for counting fast edges. A 32-bit counter counts from a parameterisable
starting value up to a parameterisable comparison value and then outputs a corresponding status
signal.
• Possible counting range: 0 ... 2 31 - 1 (0 ... 2147483647)
Function assignment 4: DI1=CountIn / DI2=In
This setting in
C00115 configures the input terminal DI1 as counting input. The input terminal DI2
remains configured as "normal" digital input..
Short overview of parameters for the counting inputs:

Note!
• The starting value must be have been set so that it is smaller than the comparison
value. Otherwise, the counter will be kept at the starting value because the condition
"Count value ≥ Comparison value" has been satisfied.
• Note the maximum input frequency of the input terminal:
• DI1: f
max
= 10 kHz
