A.2.8 Transmission times on the PROFIBUS−DP
No te
Observe here the cycle time of your PLC and the update
time of the PROFIBUS−DP.
The time delay within the CP system depends on the amount
of data and therefore on the extension to the CP system.
It amounts to:
.
2 ms.
Please refer to the manual for your controller for ascertaining
the total time required for transmission.
