Problems solved by technology
[0005] Aiming at the deficiencies of the prior art, the present invention provides an on-site distributed input and output device with intelligent fault diagnosis function, which solves the problem that the price of the protocol chip is relatively high compared to the communication MCU. At present, there is no Mitsubishi PLC in China. The IP67 remote I / O module with high protection level of industrial Ethernet needs to purchase an additional communication module of the master station, which increases the cost of the customer on the control device side; the use of a dedicated protocol chip for the remote I / O module also increases the cost of the slave station device. Cost; In addition, at present, there is no problem with the industrial Ethernet IP67 remote IO module of Mitsubishi PLC in China

The invention discloses an on-site distributed input and output device with an intelligent fault diagnosis function. The on-site distributed input and output device comprises a PLC (Programmable LogicController), a remote IO (Input / Output) module and a CClink IE Field Basic application layer, wherein the output end of the PLC is electrically connected with the input end of a remote IO module, andthe output end of the remote IO module is electrically connected with the input end of a CClinkIE Field Basic application layer. The invention relates to the technical field of distributed input andoutput devices. In the field distributed input and output device with an intelligent fault diagnosis function, the embedded real-time operating system comprises an application layer program module, aprogram editing unit and an access control layer; an Ethernet port of the PLC is utilized to reduce the cost of the industrial Ethernet control system of the whole PLC and make up the vacancy of the IP67 high-protection-level remote I / O module; and the TCP / IP protocol can be implemented in the remote I / O module by the aid of Ethernet protocol chips, and the Cclink IE Field Basic application layerprotocol can be implemented by the aid of embedded real-time operating systems, thus achieving the aim of reducing the cost.
Description
technical field [0001] The invention relates to the technical field of distributed input and output devices, in particular to a field distributed input and output device with intelligent fault diagnosis function. Background technique [0002] Generally, the power supply module is inserted in the first slot, numbered 0, the PLC is inserted in the second slot, and various types of input and output modules are inserted in the remaining slots. A printed circuit board with connectors, which can connect the slots inserted into the I / O modules. The upper and lower sides of the slots can make the inserted modules line up. The guide rails with I / O modules and processors are Called the local I / O rail; the rail with the I / O module, power supply, remote I / O communication card and installed away from the local I / O rail is called the remote I / O rail, the number of remote I / O rails Depending on the number of variables that can be controlled by different processors, the communication betwe...
