Because RS-485 MODBUS only implements the physical layer, it is difficult to solve different manufacturers of equipment to coexist in the same system problem. To this end, MODICON developed a RS-485 builds on the "application layer protocol" --MODBUS. Protocol specifies the format of the data packet, the command to achieve the like. Any equipment manufacturers, as long as it meets the MODBUS protocol can work in the same system. Uye MODBUS protocol only supports single host, and to achieve a shared channel by polling mode. Brush: The silver-palladium alloy, precision metal molds made by stamping. Thickness of 0.08mm displacement sensor, the effective length of 7.80mm ktf elastic displacement sensor, wiper contacts height of 1.00mm mts displacement sensor unit linear contact area is 0.22mm2. Silver-copper-zinc alloy material with high electrical conductivity 50mm displacement sensors, flexible, excellent abrasion resistance, in line with the brush performance requirements. After molding the brush again after the spot welding process by positioning bracket fixed to ensure the working height (wear-life) between the brush and the circuit board, repeatability, resolution in line with industry standards. Single brush structure can guarantee the electronic device has a small clutter, while ensuring that the electronic device in the whole life cycle has a very high resolution. 50mm displacement sensor _ _ Miran displacement sensor technology provided by the Shenzhen Municipal Science and Technology Co., Miran.
