Network Topologies - Kaco Blueplanet 87.0 TL3 Series Manual

Attach the DRM 0 safety sticker
According to AS/NZS 4777.2:2015, in Australia PV devices are marked that support
the "Mode 0" remote control command.
F Attach the supplied sticker next to the name plate on the device housing where it
is clearly visible.

5 Segment Controller
This illustration shows a possible variant for multiple segments. Depending on the local conditions, a different positioning
of the components may also be preferable (e.g. position Segment Controller at a central location and connect in
the segment switch via glass fibre cable).
Located directly after the Gateway VPN-Router, is the main network switch via which the segment con-
troller is connected in. With the corresponding system size (distance from main network switch to the seg-
ment controller >100 m), it may also be necessary to connect in segments that are further away via a glass fibre
connection.
Within a segment, the KACO devices can be coupled to one another via the integrated switch in an Ethernet daisy chain,
whereby the segment controller is connected to the first element of the chain. This topology is displayed in segment 2, for
example. A Segment Controller can manage up to 100 nodes. A node in this sense is any data source that is moni-
tored by the Segment Controller. (Example: 45 pairs consisting of inverter and string combiner (90 nodes) + 10 re-
serve nodes for other substation/segment data sources)
