21.2.12 Galvanic RS485 communication module
21.2.12.1 Introduction
The Galvanic RS485 communication module (RS485) is used for DNP3.0 and IEC
60870-5-103 communication. The module has one RS485 communication port. The
RS485 is a balanced serial communication that can be used either in 2-wire or 4-wire
connections. A 2-wire connection uses the same signal for RX and TX and is a multidrop
communication with no dedicated Master or slave. This variant requires however a control
