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 30]. 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 blueplanet 87.0-165TL3 can support up to 10 Modbus clients.

Start-up options
Option 1:
Local, guided start-up by means of WIFI or LAN con-
nection
– Installation technician connects to a KACO inverter
via WIFI
– Installation wizard carries out start-up steps inter-
actively.
Option 2:
Local start-up with pre-arranged configuration
– Installation technician uses a USB memory stick
that contains a pre-prepared device configuration.
– The device imports these settings and is then
ready for operation.
Option 3:
Start-up in a network without Segment Controller
– Start-up in an existing network
– The installation technician can start up the device
with the aid of the installation wizard as described
at option 1. The device can be addressed using its
host name.
Tab. 3:
Start-up variants for individual devices/plant segments/overall plant
Option 4:
Centralized start-up via Segment Controller
– A device configuration that is available on the Seg-
ment Controller can be uploaded to several KACO
inverters.
– The devices are ready for operation once the con-
figuration is activated.
Option 5:
Centralized start-up via Plant Controller
– Available in future development levels.
– A device configuration that is available on the
Plant Controller can be uploaded to the relevant
devices via the subordinate Segment Controllers.
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-compati-
ble adapter. If such an adapter is not available, the other option is to perform an automatic configuration using
a USB memory stick.
Application
The planned network infrastructure or AC-coupling is not yet in place or has not been completed.
Required components
– WiFi-compatible notebook, tablet or smartphone (Android or iOS devices can be used).
– USB WiFi stick (KACO accessory, type: WLAN adapter Digitus 150 N micro article no.: 3013222)
