6.3.3 External continuous measurement / External special via process channel
Fig. 17: Timing diagram for external continuous / external special measurement via process channel
1)
In case of “Function fault“ “Function result“ is not necessarily set.
2)
The measuring time depends on the averaging.
* The status of the 0 -, 1 -, 2-sheet and warning outputs is refreshed via the fieldbus (BOUT8.4-7) with a refresh rate of
6 ms. Through the I / O outputs (OUT), the rate is 1 ms.
Note
The output “Function result“ is set with the appearance of the first
measurement value and then remains set.
Note
In the “extern special” measurement mode the highest measured value
will be displayed and held at the outputs until a new measurement is
started.
Note
The measured timing periods were determined with12 Mbit/s Profibus.
These timing periods can vary with different transmission rates and bus
systems. The cycle time of the PLC has not been taken into account.
