WebModbus Interface Specification 4.1 Modbus physical layer DK-RC-MBS-1 implements a Modbus RTU (Slave) interface, to be connected to an EIA-485 line. WebThe Modbus communication interface is built around messages. The format of these Modbus messages is independent of the type of physical interface used. On plain old RS232 are the same messages used as on Modbus/TCP over Ethernet. This gives the Modbus interface definition a very long lifetime.
