electrical connections

6.3  DIGITAL COMMUNICATIONS CONNECTION

6.3.1 Via MODBUS RTU

1) PTU50, PTU51 o PTU56 with MODBUS RTU communication protocol
2) USB/RS485 interface module, cod.694A004A
3) MODBUS RTU communication S/W, cod.010F105A
With this software is possible:
- connect, by selecting the UID address, the PTU50, PTU51 or PTU56 transmitters in MODBUS RTU network
- read on your PC monitor all measures in reading and operation data
- programming all confi guration parameters
- storing on fi les, data logger function; measures in reading and operating states
