Operation
Met One 6000 counters with the RS485 Modbus communication option use
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 Appendix A on page 53 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.
Set the instrument address—RS485
Important note: Address 0 can only be used with FXB protocol. Address 0 is reserved for
use as a broadcast address for Modbus RTU.
For a network of counters with RS485 Modbus or FXB protocol, use the dip switch on the
bottom of the counter to set the address (refer to Table 8).
