Network load
The following table shows the generated cyclical real-time network load per PROFINET device. A PROFINET packet size of 60 bytes and a PROFINET data rate of 100 Mbit/s is assumed
Refresh time ms | Network load % |
|---|---|
1 | 0.86 |
2 | 0.43 |
4 | 0.22 |
8 | 0.11 |
In order to leave sufficient reserves for extensions and especially for NRT (Non Real Time) communication, observe the following limit values for network load of cyclic real-time communication when planning the PROFINET network:
Network load | Recommendation |
|---|---|
< 20% | No action required. |
20% – 50% | Check the planned network load. |
> 50% | Reduce the network load. |
