The Electronic scale comes with an RS-485 (MODBUS-RTU) interface, while the serial communication port of the PC is an RS-232C interface, and the two need to communicate with each other via the SC-09 adapter cable. Electronic scales use the RS-232C standard to transmit signals using the voltage difference between the signal line and the common ground, using a unidirectional transmission method, while the RS-485 standard uses the voltage difference between the signals of the transmission lines to transmit, using a differential transmission method. the SC-09 cable realizes the conversion between these two different signal transmission methods.

The electronic scale picks up the weight through the pressure weighing module, and amplifies and filters the picked up weight signal, then enters into the A/D converter for analog-to-digital conversion, and then sends it to the weighing instrument to analyze and process the signal, and the result is outputted to the industrial control through the RS232C communication serial port, and at the same time, it makes the corresponding reaction and executes the corresponding operation according to the result of the signal. Adopting the batching centralized control mode, it is linked by a host and multiple slaves through the network, and the host will give the control task to each slave to complete. The whole industrial control machine batching is divided into industrial control electronic scales and weighing instruments.

In order to control personnel directly accurate raw material weighing data, the production process can not be a small amount, lack of material, loss of material. To realize the manual or automatic to select the bin number location, the bottom line of the inventory of various ingredients for automatic alarms and other functions, the digital display of the electronic scale and the PLC and touch screen for information exchange, all the system control will be brought together in a special system software, the controller only need to click the appropriate location to control such as electrical switches, rotating transport components, water, gas valves, etc., the human-machine interface is very good! The human-machine interface is very good to the entire production line through the dynamic and static diagram form displayed on the computer screen above, the staff can not leave home to understand the operation of the entire production of ingredients.
