Master drivers for RS-485 must be placed in the middle of slave devices to take advantage of the standard’s impedance guidelines. With RS485 it is possible to set-up a multi-point application with one master and several slaves. For master configuration choose "Master" as type and input the addresses of the slaves in the RS485 bus as a comma separated list. A RS485 bus consists of one master and multiple slaves. Is there an easy way to log data to a PC from multiple instruments on an RS485 bus? PWBS331 DC transmission data bus chip achieves the function of delivery both of the UART data and DC power on only two wires. The normal way to implement this is with a two wire system with differential signal levels. Further considerations include whether the system will need full- or half-duplex. To gain a toe-hold in the sector, as well as to address what the company projects will be a worsening skills gap as retiring engineers and developers aren't being replaced with fresh blood boasting the necessary talents, Arduino has launched the PLC Starter Kit - a bundle that includes its range-topping Opta WiFi "mini PLC," two quick-start simulator boards for inputs and outputs, and all the accessories you need to get everything running, plus a free online training course claimed at 20 hours of content.
Will the data drop over time. It describes how to program the baud rate using Timer 1 registers and explains data transfer using the SBUF, SCON, TI and RI registers.

RS-485 is used as the physical layer underlying many standard and proprietary automation protocols used to implement industrial control systems, including the most common versions of Modbus and Profibus. In fact, there is no such thing as an RS485 cable since RS485 is a protocol for serial communication (like between inverter and Zero export device) and Ethernet is a protocol for carrying internet data (between router and inverter) whereas CAT6 is a cable standard. There are 16 meters in loop. Use Laurel’s 6-wire data cables CBL03-1 (1 ft) and CBL03-7 (7 ft) to interconnect meters if these lengths fit your application.
