Parameters of the Counting mode

Parameters of the DI 32x24VDC HF Count in the Counting mode
If you want to use the module for counting, you need to set the module parameters as DI
32x24VDC HF Count. For channels 0 and channel 1, the following parameter settings are
then possible. For channels 2 to 31, the parameter settings apply as with the DI 32x24VDC
HF, , see section Parameters DI mode (Page 16).

Behavior when a count-

* If you enable diagnostics for multiple channels, you will receive an alarm storm on failure of the supply voltage because
each enabled channel will detect this fault.
You can prevent this message burst by enabling diagnostics for one channel only.
** Comparison value or start value must be less than or equal to the value for the high counting limit.
