Modbus RTU
You can use Modbus RTU protocol to control the device parameters with an automation control system
or any Modbus master device. To enable communication through Modbus RTU, connect the device to
the master device with the RS-485 bus.
For information on how to control slave devices, refer to the user documentation of your Modbus
master device or control system.
For a quick reference of the register definitions of the Modbus RTU interface, see
Appendix B .
For information on how to connect the RS-485 bus, see section Connecting RS-485 bus in chapter
Electrical installation .
Sintrol Network
You can use Sintrol Network protocol to connect the device to a computer running DustTool software.
To control the device parameters using Sintrol Network:
1. Connect the device to a computer with the RS-485 bus.
2. Use DustTool software to change the device parameters.
For information on how to change the device parameters using DustTool, see section DustTool software
in this chapter. For a more detailed overview of the DustTool software, see chapter DustTool .
For information on how to connect the RS-485 bus, see section
Connecting RS-485 bus
in chapter

8.2.4 Wireless connection
If your device is equipped with the optional RF antenna, you can use DustTool to remotely control the
settings and parameters of devices that are part of a wireless network.
For information on how to change the device parameters using DustTool, see section
DustTool software
in this chapter. For a more detailed overview of the DustTool software, see chapter DustTool .
For information on how to enable wireless communication for the device, see section Establishing
wireless communication in this chapter.
8.3 Setting up device network
RS-485 bus allows multiple devices to be connected in parallel to create a device network. This makes it
possible to communicate with several devices at the same time with minimum wiring. Wired
connections can use either Modbus RTU or Sintrol Network protocol for communication. Wireless
communication, and combination of wired and wireless connections require the use of Sintrol Network
protocol.
A complete measurement system that is based on Sintrol Network protocol can consist of up to 254
devices connected to a single network. These can be connected either wirelessly, with the RS-485 bus, or
with a combination of the two.
