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).
