Field bus system and field bus recognition method

Abstract

The invention provides a field bus system and a field bus recognition method. The field bus system comprises a recognition module, at least one field bus module and configuration modules or GPIO modules corresponding to the field bus modules in a one-to-one mode. The field bus recognition method comprises the steps of reading the storage space of the configuration modules by accessing the configuration modules or GPIO modules corresponding to the field bus modules, recognizing the field bus modules according to a read data value, or reading electrical level states of GPIO vase pins of the GPIOmodules, and recognizing the field bus modules according to the electrical level states of the GPIO vase pins of the GPIO modules. According to the field bus system and the field bus recognition method, attribute information of the field bus modules can be quickly recognized by a user, the automation degree is improved, and the work efficiency is also improved.

Description

technical field [0001] The invention relates to the field bus technology field, in particular to a field bus system and a field bus identification method. Background technique [0002] Industrial control systems, terminals, relays and other equipment often require a large number of industrial fieldbus modules, such as RS232 modules, RS485 modules, RS422 modules, B code decoding modules, etc. Industrial control equipment generally contains several fieldbus modules. In actual use, customers can freely combine fieldbus modules in industrial control equipment according to actual applications, so as to meet the needs of different applications. However, due to the similar design of the industrial fieldbus modules in terms of dimensions and interface methods, it is difficult for non-professionals to judge which fieldbus module it is from the appearance alone. The model of the module, and then look up the manual according to the model to learn the type and function of each module, ...
