Description

Technical Field

[0001] The present invention relates to the technical field of industrial intelligent control, and particularly to an intelligent control instrument. Background Art

[0002] With the development of industrial Ethernet, more and more concise control methods are required for control systems or on-site maintenance. There are generally three ways to control or set parameters of the existing weighing system: 1. Using the keyboard and screen built into the weighing system terminal to manipulate or set instrument parameters.

[0003] This method is limited by the size of the weighing instrument housing, and the amount of information that can be displayed on the screen is relatively small. Moreover, it is necessary to go to the site of the weighing instrument one by one for setting. If the number of installed weighing instruments is large and scattered, it will bring inconvenience to control operations.

[0004] Manipulating or setting the parameters of the weighing instrument through other field buses such as serial ports or RS485. This method requires the use of additional communication methods and tools, significantly increasing the complexity of the system.

[0005] Setting the PLC program or PLC controller in advance to manipulate or set the parameters of the weighing instrument.

[0006] Although this method uses the existing industrial Ethernet, avoiding additional wiring and increasing the complexity of the system, the programming of the PLC program or the setting of the PLC controller is professional and complex, so it is not intuitive and convenient to use. Therefore, it is not conducive to the setting and operation of the weighing instrument by general on-site maintenance personnel. Summary of the Invention
