9.8.3 1 counter 32 bits, 5 V DC - EPM-S602
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
Continuous counting The counter counts from the loading value to the counting limit, then skips to the
opposite counting limit and continues to count from there.
Counting once The counter counts once/periodically from the loading value in the specified
counting range.
Counting periodically
Signal evaluation Description
Single rotary transducer Connection to "A/pulse" input
Double rotary transducer
Quadruple rotary transducer Connection to input "A/pulse" and "B/direction"
Direction Pulse at "A/pulse" input and direction at "B/direction" input
Additional functions Description
Main counting direction The main counting direction can be parameterised:
None: The entire counting range is available.
Forwards: Limitation of the counting range upwards. The counter counts from the
parameterised loading value in the positive direction to the parameterised final
value -1 and then skips to the loading value again with the encoder pulse that is
following.
Backwards: Limitation of the counting range downwards. The counter counts from
the parameterised loading value in the negative direction to the parameterised final
value +1 and then skips to the loading value again with the encoder pulse that is
following.
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).
The following response can be parameterised:
Cancelling gate function: After closing the gate and opening it again, the counting
process continues from the loading value again.
Interrupting gate function: After closing the gate and opening it again, the counting
process continues with the last current counter content.
Comparator You can specify a comparison value which, depending on the count value, activates
the digital output or triggers a process alarm.
Hysteresis By specification of a hysteresis you can for instance prevent the output from being
permanently switched if the value of an encoder signal fluctuates around the
comparison value.
Process alarm The activation of a process alarm can be parameterised. A process alarm can be
triggered in the case of the following events:
•Open hardware gate
•Closed hardware gate
• Counter limit overflow
• Counter limit underflow
• Comparison value reached
• Final value reached
• Latch value reached
Diagnosealarm If the diagnostic alarm is enabled in the parameter setting, it occurs if another
process alarm is triggered for the same event during a process alarm processing.
