The process bus is available for all merging units. See the IEC 61850 engineering
guide for detailed system requirements and configuration details.

Secure communication

The merging unit supports secure communication for WHMI and file transfer
protocol. If the Secure Communication parameter is activated, protocols require TLS
based encryption method support from the clients. In this case WHMI must be
connected from a Web browser using the HTTPS protocol and in case of file transfer
the client must use FTPS.
