industry-standard Modbus RTU protocol. In this communication mode, a series of
registers hold data about measurement results and operation parameters. The
parameters are preset by the user through a utility setup program or through the central
monitoring software. A list of tables in
shows the register
addresses, types and use. A user must write drivers to communicate with the particle
counter through these registers with the Modbus RTU protocol.
