Problems solved by technology
[0002] There are generally two ways to collect signals. One is to connect the field equipment to the input and output channels of the controller through hard contacts. This method is relatively direct, but the cost is high and the reliability is low; the other way is the field equipment. The signal is directly sent to the controller through serial communication. This method is low in cost and high in reliability, but requires high communication functions between the device and the controller.
At present, as field devices are becoming more and more intelligent, in order to save costs and improve reliability, more and more signals are not sent through hard contacts, but are required to be sent to the controller through serial communication; in addition, due to some special signals, The controller cannot collect, and it must be collected by other devices and then sent to the controller through the serial port
