Abstract

The invention discloses a method and system for automatic configuration of an I / O port, wherein the method applied to a central processing unit includes: receiving request information from a controlled device, wherein the request information carries information required by the controlled device The signal type; according to the signal type, send configuration instructions to the control device to instruct the control device to configure the I / O port according to the configuration command; where the controlled device is directly connected to the central processing unit, or the controlled device is connected to the central processing unit through the control device Processor connection. Thus, a communication link between the central processor and the controlled device can be established, so that the central processor can automatically generate configuration instructions according to the signal type required by the controlled device to instruct the control device to configure the I / O port. In this way, the automatic configuration of I / O ports can be realized, unmanned operation can be realized, and the risk caused by human misoperation can be avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an I / O port automatic configuration method and system. Background technique [0002] At present, automatic control devices such as PLC (Programmable Logic Controller, programmable logic controller), DDC (Direct Digital Control, direct digital control system) are rapidly popularizing. This type of automatic control device is mainly used for centralized control of various large machinery or complex equipment. The control device itself integrates various types of input and output interfaces, these interfaces include digital input and output interfaces, analog input and output interfaces, and the analog input and output interfaces include voltage input and output interfaces, current input and output interfaces, and temperature sensor packages detection interface, etc. In order to enhance the function of the port and improve the versatility of the port, a port can be d...
