Redundant, high availability terminal bus with SIMATIC NET SOFTNET‑IE RNA
All protocols among the redundantly connected components are automatically duplicated, sent
and distributed in the mutually redundant networks. The respective receiver uses the first
incoming frame with the same information from the redundant networks.
Advantages:
● Easy administration
● A fault on one bus has no effect on the redundant bus
Components
SCALANCE series switches are used to connect the components. Recommended switches
that support the Parallel Redundancy Protocol may be found in the Process Control System
PCS 7; Released modules documentation.
