Splet21. avg. 2016 · MODBUS is a protocol between a host (master) and devices (slaves) to access the configuration of the devices and to read the measures. MODBUS messages correspond to relatively simple operations to read and write 16 bit words and binary registers (often called "coils"). The host systematically initiates the exchange and the … RS-485 is also used in building automation as the simple bus wiring and long cable length is ideal for joining remote devices. It may be used to control video surveillance systems or to interconnect security control panels and devices such as access control card readers. Prikaži več RS-485, also known as TIA-485(-A) or EIA-485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems.
