Abstract

Provided is an extension module for independently storing calibration data, including: a first interface (101), adapted to receive a first external input signal; a second interface (102), adapted to output the first output signal of the extension module; a signal processing circuit (103), connected between the first interface (101) and the second interface (102); and a first memory (104), the first memory (104) storing first calibration data, and the first calibration data being associated with the extension module (10). Furthermore, also provided is a component using the above extension module, and a component calibration method. On the one hand, the extension module may share an ADC sampling circuit (204) on a main module (20), so that the manufacturing cost of the extension module is reduced. On the other hand, it can facilitate the replacement of different extension modules for the main module without repeated calibration.

Description

technical field [0001] The invention relates to an expansion module, a component and a component calibration method for independently storing calibration data. Background technique [0002] In the field of industrial motion control, some products need to be designed as a main module that can work independently and support an extended modular architecture. The expansion module has the analog input or output function of several channels. In consideration of cost reduction, it is hoped that the analog circuit on the expansion module shares the ADC sampling circuit on the main module, and only the signal conditioning circuit and port protection circuit are reserved on the expansion module. [0003] For example, in the case of analog input, in order to meet the requirements of product analog accuracy, the production line needs to calibrate each product. However, the calibration data of the entire loop of each channel is related to both the main module and the expansion module. ...
