Figure 40: System network of two inverters (example)
Monitoring and control can be organized in two separate networks:
• Monitoring network
This network is used for monitoring, parameterization and remote diagnosis.
• Control network
The grid operator uses this network to transmit grid management specifications to the inverters. The control
network is used exclusively for grid management services that need to be transmitted and implemented within a
specified time period.
If only a low data transfer rate is required for monitoring, grid operator specifications can also be transmitted via the
monitoring network. Only one network is required in this case.
