3.3 Application configuration A
3.3.1 Applications
The application configuration A is mainly intended for sharing currents and voltages
over the process bus in the digital MV switchgear (main or backup).
The merging unit with an application configuration is delivered from the factory
with default settings and parameters. The end-user flexibility for incoming,
outgoing and internal signal designation within the merging unit enables this
configuration to be further adapted to different primary circuit layouts and the
related functionality needs by modifying the internal functionality using PCM600.
