8 | Start-up
Within a segment, it is possible to link KACO devices to one another as part of an Ethernet daisy-chain by way of an inte-
grated switch, whereby the Segment Controller is connected at the first element in the chain. For this purposes of an ex-
ample, this topology is shown in segment 2. A Segment Controller can manage up to 100 nodes. A node in this
sense is any data source that is monitored by the Segment Controller. (Example: 45 pairs consisting of inverter and
string combiner (90 nodes) + 10 reserve nodes for other substation/segment data sources)
If additional failure safety is desirable, the KACO devices can also be arranged in a ring via a correspondingly configured
Network Segment Switch (that supports the Rapid Spanning Tree Protocol "RSTP"). This switch is then also coupled
to the Segment Controller. For this purposes of an example, this configuration is shown in segments 1 and M.
As can be seen in the figure, a string combiner is assigned to each KACO device. In terms of communication, these
are connected to the device directly via an RS485 cable (green cable – note connection port in [See sec-
tion 7.9.1} Page 33]). To this end, MODBUS RTU is used as a communication protocol.
The monitoring of the string combiner is also carried out via the Segment Controller, whereby the KACO de-
vice undertakes the role of a MODBUS gateway. The string combiner must be coupled using a DC–Combiner.
There is no restriction as the compatibility depends on the segment controller and string combiner selected. (e.g.
blue´Log is compatible with Weidemüller DC-Combiner)
When a blue´Log device is used, the only 3rd party string combiner device currently available, which can also be ad-
dressed in this manner via the Segment Controller, comes from "Kernel Sistemi".
Depending on the network load, the device can support up to 10 Modbus clients.

8.4.1 Start-up via WIFI
To start up the device directly, the first option is to carry out the installation interactively with a WIFI-compatible adapter.
If such an adapter is not available, the other option is to perform an automatic configuration using a USB memory stick.
