Description
Pulse at device input I1 – I8, which
is defined as a counter input in the
parameters.
Duration signal at device input I1 –
I8, which specifies the counting dir-
ection.
0: up counting
1: down counting
Pulse at device input I1 – I8 counts
up.
Pulse at device input I1 – I8 counts
down.
Double evaluation
With automatic up/down counting dir-
ection detection, two counter inputs
I1...I8, counter input channel A,
pulse
I1...I8, counter input channel B,
pulse
6. Function blocks
6.2 interrupt function blocks
Note
Maximum frequency 5kHz
