Function block type:
Function block (FB)
Library:

Description
23299
The FB is used to configure and to operate a digital input pair to record and count incremental encoder
pulses.
Two frequency inputs constitute the input pair (channel A and channel B) that is configured and
evaluated via the FB.
Behaviour at the counter limits
If the applicable value range is exceeded, the output switches to the minimum value of the applicable
area. (= overflow)
If the applicable value range is not reached, output switches to the maximum value of the applicable
area. (= outside range)
