Please send your best support. Thanks you

In a sense turning the counter counts ok, but in the other direction of rotation of the account is incorrect. we have connected: Channel A and Channel B Channel B and Channel A we set the counter as incremental and also as a counter decrement and does not work. Please send any suggestions Attachment fault counter.pdf (1017 Downloads)

(doesn’t count, count in the same way, lose pulses…)?

The parameter HSC input the address for the Hardware (Ex. ID1000). For visualization, open the Watch Table with address ID1000.
