5.5 RS485 Modbus communication protocol
The digital communication protocol is based on standard Modbus RTU Half-plex mode. A master
(PC or PLC) can communicate with multiple slaves (the current product) for data exchange and
communication parameter configuration.
5.5.1 Hardware connection
The hardware layer is
TIA/EIA
-485-A, as illustrated below. In this configuration, the product
(MF5806E1) is a slave.
