2.1.2.3 Description
The Up/Down counter 750-404 and the variation 750-404/000-004 is capable
of counting binary pulses of DC 24 V at the input CLOCK and then transmits
the data to the fieldbus.
The counter module 750-404/000-002 begins processing with pulses at the
CLOCK input and counts the pulses in a special time span. The time span is
given as 10 s.
The changes from 0 V to 24 V are counted
The counter counts up, if the input U/D is set at 24 V. With an open circuit
input or 0 V the counter counts backwards.
