PROmesh P20 - User Manual 18
The PROmesh P20 fully supports the IEC 62439 standard and enables deterministic convergence of the
information forwarding with simple redundancy (ring topologies, see Figure 7). Depending on your system,
convergence times of max. 200 ms (500 ms) thus becomes possible.

2.7.1 Ring redundancy
The PROmesh P20 makes it possible to set up simple ring redundancies, as described in Section 2.7.
The following function protocols are used to set up ring structures.
2.7.1.1 Netload balancing
In the meshed networking of subnetworks, specific connections frequently have high data traffic.
It is particularly noticeable that this data traffic frequently takes the form of load peaks in the
communication and thus it is difficult for system operators to calculate it. To ensure fail-safe operation
of the automation system, unlimited data forwarding is required even under these conditions.
