Description
Note
Counter with external direction
control
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
Maximum frequency 5kHz
Counter with 2 counter inputs
Pulse at device input I1 – I8 counts
up.
Pulse at device input I1 – I8 counts
down.
incremental counter
X2
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
When there is a complete channel A
and B period (e.g., first channel A
edge to next channel A edge), the
value at IC..QV is incremented or
decremented by 2 depending on the
