Two counters 32 bits, 24 V DC − EPM−S603

By integration of the GSE file VI010C19.gse you can specify all counter parameters via a
hardware configuration.

The following functions can be parameterised:

Counting functions

Description

Counting
continuously

The counter counts from 0 to the counting limit, then skips to the opposite counting limit
and continues to count from there.

Signal evaluation

Description

Single rotary
transducer

Connection to input "A/pulse" and "B/direction"

Double rotary
transducer

Quadruple rotary
transducer

Direction

Pulse at input "A/pulse" and direction at "B/direction"

Additional functions Description

Gate function

The gate function serves to start, stop, and interrupt a counting function. In the case of
this counter the internal gate (I−gate) is conform to the software gate (SW gate) which
you control via your user program (status word in the output area).
