Problems solved by technology
[0003] The advantages of controllers designed with ASIC chips are obvious. The first is stability, and the second is high speed. However, the technology is mainly monopolized by foreign companies, and the interface is not open to ordinary users, and users cannot perform secondary operations. secondary development
[0004] Disadvantages of industrial control PC: first, it is large in size; second, the operating system uses linux or windows, which are not real-time operating systems, and is not suitable for industrial control occasions; third, the industrial control PC itself does not have the hardware to run the field bus, so it needs to be integrated into it

Embodiment Construction
[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:
[0015] see figure 1 , is a structural schematic diagram of the controller of the present invention.
[0016] The controller includes a main controller 100 and a backup controller 200 for synchronous communication, and is the basic control unit of the entire control system. After configuration and configuration, the controller can form a distributed control system. In this embodiment, a single controller is taken as an example for illustration.
[0017] The main controller 100 of this controller comprises main processor 101, and this main processor 101 is provided with Ethernet interface 102 and Fieldbus Profibus interface 103, and this Ethernet interface 102 is connected with Ethernet 104, and this Fieldbus Profibus interface 103 is connected with Profibus main line 105.
[0018] Described standby controller 200 comprises standby processor 201, an...

The invention provides a controller. The controller comprises: a main controller and a standby controller, wherein the main controller and the standby controller are communicated synchronously. The main controller comprises a main processor. An Ethernet interface and an on-site bus Profibus interface are arranged on the main processor. The Ethernet interface is connected with an Ethernet. The on-site bus Profibus interface is connected with a Profibus bus. The standby controller comprises a standby processor. The Ethernet interface and the on-site bus Profibus interface are arranged on the standby processor. The Ethernet interface and the on-site bus Profibus interface are connected with the same Ethernet and the same Profibus bus which are connected with the main processor respectively. A general industrial processor, which is used in the invention, can be embedded into a Nucleus multitask real-time operation system and a TCP / IP / UDP protocol stack. The controller can be widely used in various kinds of industrial control occasions.
Description
technical field [0001] The invention relates to the technical field of automatic control, in particular to an industrial controller. Background technique [0002] In the field of automation control technology, the controller is the core module of various electronic equipment. At present, the controllers used in the industry are generally designed by ASIC (Application Specific Integrated Circuit) or industrial control PC. Typical PLCs such as s7-300, S7-400, and Ilon100 developed by Siemens, Germany. [0003] The advantages of controllers designed with ASIC chips are obvious. The first is stability, and the second is high speed. However, the technology is mainly monopolized by foreign companies, and the interface is not open to ordinary users, and users cannot perform secondary operations. secondary development. [0004] Disadvantages of industrial control PC: first, it is large in size; second, the operating system uses linux or windows, which are not real-time operating s...
