3 Connecting devices to Modbus
For all devices connected to the same network, the Modbus communication
parameters need to be set to the exact same values. In addition, the
corresponding Modbus addresses must match. Once these prerequisites are
met, the BreakerVisu program will be able to detect these devices and
graphically display and log the corresponding data.
3.1 Modbus RTU communication parameters
The settings with Modbus BreakerVisu as a master can be configured in
Extras
, under
Modbus-RTU Settings
.
Figure 20 describes it for the
7“ variant and
Figure 28 describes it for the 3.5“ variant. These are the
settings that the Modbus RTU master will use to communicate with all
slaves.
3.2 Discover devices
The detection routine for connected devices needs to be run every time the
BreakerVisu program is started (e.g., when the device is switched on,
restarted, etc.) if new devices are connected to the network. Once the new
device is detected and identified, all the corresponding device data will be
read. If there are no devices on the Modbus RTU network, the home screen
will display the “Press to discover Modbus-RTU devices” button in the
7“ variant and the “Discover Devices” button in the 3.5“ variant on the
home screen. Simply tap the button to start scanning the Modbus RTU
network with the actual Modbus RTU communication parameters. If you
need to change the Modbus RTU communication parameters, or if there are
any devices that are already in BreakerVisu and that require a new detection
scan, go to
Extras
->
Modbus-RTU Settings
. Then tap the
Discover
Devices
button to start scanning. While the detection process is in progress,
the scanning results will be shown directly in the
Discover Devices
button
and in the home screen. Once it is completed, the total number of connected
devices will be updated in the home screen.
If the connection to a device drops out during operation, it will be
automatically removed from BreakerVisu after a certain time. If the device is
connected to the network again, you will have to tap the
Discover Devices
button again in order to add the device back to the BreakerVisu program.

Please consult the installation manual for each device and follow
the corresponding configuration instructions.
The “Eaton Modbus Configurator” program is available for
configuring the Modbus parameters for NZM-XMC devices.
It is available from the Eaton website at
