The automatic processing apparatus provided in the embodiment of the present application includes all technical features of the processing system of the analog quantity as described above, and has the technical effects corresponding to all technical features of the processing system of the analog quantity as described above, which are not described in detail herein.

Preferably, the device further comprises an upper computer or a display screen, wherein the upper computer or the display screen is used for displaying each preset analog input data to be selected and input by a user.

Specifically, the display devices adopted by the apparatus provided by the embodiment of the application are different in different application fields. When the device is in a more complex application environment and has a larger project, the embodiment of the application can display each preset analog input data to be selected and input by a user through the upper computer; when the device is in a simpler application environment and has smaller projects, the embodiment of the application can be directly connected with the display screen through the human-computer interface on the device, and then, the preset analog input data to be selected and input by a user is displayed through the display screen.

Preferably, each preset analog input data to be selected and input by a user can be displayed on the upper computer in a form of a table, and a plurality of or all of a target actual analog output signal, an upper limit alarm state signal and a lower limit alarm state signal can also be displayed.

In this application embodiment, the data that need input can be selected according to each preset analog input data that the host computer shows, for example: if the upper limit alarm is needed, inputting an actual upper limit alarm value at the upper limit alarm value InUpDp; if lower limit alarm is needed, inputting an actual lower limit alarm value at a lower limit alarm value InLowDp; if the alarm needs to be delayed while the upper limit alarm is given, the actual upper limit delay time is input at the upper limit alarm delay time TdUp; and if the alarm needs to be delayed while the alarm is given at the lower limit, the lower limit actual delay time is input at the lower limit alarm delay time TdLow. Ordinary technicians or first-party personnel can test products or control systems through the upper computer without relying on the operation of real equipment, and the working efficiency is improved.

Preferably, the operation module of the processing system is a PLC. Furthermore, the efficiency of code automatic generation can be improved to a certain extent.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
