Technical data of the fast counter inputs
The AC500-eCo V3 processor modules with onboard I/Os provide some special functionality on
the digital inputs or digital outputs. Fast counter, encoder inputs, interrupt inputs or PWM/PTO
outputs are available depending on the device used.
The fast counter functionality can be activated within the onboard I/O configuration.
The fast counter can work in pulse/direction mode or A/B track counter mode.
The pulse/direction counter detects the rising edge of the counter input. It will increase or
decrease the count value (depending on the direction input) at every rising edge.
The A/B track counter is used to count the signal from an encoder.
The counter can count with quad phases. In the following the behavior of the A/B track counter
is described.

For AC500 devices the function "fast counter" is available in S500 I/O modules
as of firmware version V1.3.
For AC500-eCo V3 devices the function "fast counter" is available in onboard
I/Os of PM50xx.
