7.6.2 Trigger Counter
7.6.2.1 General
The trigger counter is used to supplement the existing additional information in the sensor.
Use one of the following for selection:
- Data Selection web interface page
- command OUTADD_ETH
These data are not available for the RS422 interface and in EtherCAT mode.
The trigger counter consists of the following 4 elements:
- trigger ID (T)
- trigger event counter (TriggEventCnt)
- trigger measurement value counter (TriggValueCnt)
- reserved bits (r)
31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
T r TriggEventCnt r TriggValueCnt
7.6.2.2 Trigger ID (T)
Depending on the selected trigger mode, Bit 31 will show if a trigger event is present:
- T == 1: trigger event available.
- T == 0: no trigger event.
Use the TRIGGEROUT ALL command to specify during trigger selection that all measurement values are going to be transferred and
that T== 1 is used to mark the trigger event. In the gaps between two trigger events T == 0 is indicated.
7.6.2.3 Trigger Event Counter
The trigger event counter counts the number of trigger events. Each trigger edge (presets LH or HL) increases the counter by 1. The
counter has a bit width of 14 bit which are the lower 14 bits of the counter’s high part.
Use the RESETCNT command to reset the trigger event counter. The counter will be set to zero with the next trigger edge (preset) after
processing the command.
Counting range: 0 ... 16383.
