The counter module 750-404/000-002 begins processing with pulses at the CLOCK input and counts the pulses in a special time span.
  • Page 14 Description The counter can be set or reset with the control byte. The digital outputs DO 1 and DO 2 of the counter module 750-404 and the variation 750-404/000-002 are activated through bits in the control byte. The digital outputs DO 1 and DO 2 of the counter module 750-404/000-004 are activated depending on the counter reading or through bits in the control byte.
