6.3 DIGITAL COMMUNICATIONS CONNECTION

7.3.1 MODBUS RTU PC connection

1) FLOWMETER with MODBUS RTU communication protocol

2) USB/RS485 interface module, cod.694A004A

3) MODBUS RTU communication S/W, cod.010F119A, for FLOWMETER transmitter

With this software is possible:

- connect, by selecting the UID address, the FLOWMETER transmitters in MODBUS RTU network

- read on your PC monitor all measures in reading and FLOWMETER operation data

- programming all FLOWMETER configuration parameters

- storing on files, data logger function; FLOWMETER measures in reading and operating states
