Start continuous measurement via process channel
Fig. 44: Timing diagram for start continuous measurement via process channel
Note
The output “Function result“ is set with the appearance of the first
measurement value and then remains set.
Note
The measured timing periods were determined with 12 Mbit- 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.
