Dynamic behavior,<br />
PROFIBUS PA<br />
A typical cyclic parametrization for the PLC of 20 values per second results in the following behavior:<br />

Response time<br />
• Cyclic: approx. 10 ms per request<br />
• Acyclic: < 50 ms<br />
All values are typical values.<br />
Cycle time (update time)<br />
The cycle time in a bus segment in cyclic data communication depends on the number of devices, on the<br />
segment coupler used and on the internal PLC cycle time.<br />
Dynamic behavior,<br />
FOUNDATION Fieldbus<br />
A typical configuration for the macro cycle time (host system) of 250 ms results in the following behavior:<br />
