330180-90-00 According to the received digital input signals and intermediate variables, the tester is started and controlled to run, and the control program is shown in Figure 4. First determine the direction of the main axis of the toy, followed by measuring the main axis dimensions. After determining these, the positioning lever returns to the original position, ignites the toy and starts the timer. After the toy is burned, the timer is stopped, the positioning lever is returned to the recording position, and the burning dimensions of the toy are measured. The burn time is calculated and the printout is activated to output the test results and end the test process.

330180-90-00 In conventional automatic control systems, sensors and actuators are wired independently, and systems consisting of multiple sensors and actuators require a large number of wires. Communication bus applied to the measurement and control system can not only save a large number of wires, but also improve the reliability of the system. Industrial buses that have been widely adopted generally have two categories.

330180-90-00 A class of master-slave structure mode, such as RS-485 communication, the communication bus has been widely used in industrial control, the communication mode for the command-response mode. The host sends a query signal to each sub-controller at regular intervals, and then the sub-controllers report their respective status. This communication method is less difficult to develop, but the communication actually consumes a significant portion of the resources of the host controller.
