Abstract

The embodiment of the invention discloses a multibus IO-LINK master station supporting device. The device comprises an industrial Ethernet module, a CAN bus interface module, an RS485 communication module, an IO-LINK master station physical layer communication module, a central processing module and a wireless communication module. The industrial Ethernet module is connected with the central processing module in an MII interface mode. The CAN bus interface module is connected with the central processing module through a UART interface. The RS485 communication module is connected with the central processing module through the UART interface. The wireless communication module is connected with the central processing module through the UART interface. Periodic data and aperiodic data are processed separately. Under the condition of not changing existing upper computer control hardware architecture, IO layer devices are smoothly upgraded as IO-LINK devices. Moreover, most advantages of anIO-LINK technology are reserved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an IO-LINK master station device and method supporting multiple buses. Background technique [0002] IO-LINK is a new IO-level communication technology that has emerged in recent years. It is not a new fieldbus technology, but a point-to-point communication technology that can transmit events, configurations, Process data has been accepted as the IEC 61131-9 international standard. IO-LINK devices usually require an IO-LINK master station to act as a gateway to connect IO-LINK devices to fieldbus or industrial Ethernet for communication. As a device on the field bus, the master station interprets the information from the IO-LINK device connected to the master station, repackages it into a frame, and sends it to the fieldbus control device in real time, such as PLC, industrial computer, etc.; at the same time, the master station It is also possible to set the parameters o...
