PMX Event Counter (Trigger)
In this example, the overpassing of a force value should be counted and displayed. Once the count 5 is reached, this should be signaled on a digital output. Then the operator can set the count back to 0 again.
The following example shows how to setup an event counter in PMX. Two Calculated Channels are required therefore.
Setup a Calculated Channel „Counter“.
- Flag01 is the input signal
- Counted is only with a positive edge
- By setting a specific limit value for the flag a signal can be initiated, which will be set active when the limit value is reached
- This activates Flag02, as soon as the counter reaches a value of 5 or higher
- These Flags can be retrieved by the PLC via a fieldbus
