Summary of the invention
The purpose of this utility model is to overcome shortcoming in the prior art, it is simple to provide a kind of structure, and makes
With the convenient novel structure based on loop network control technology,.
In order to achieve the above object, the utility model uses following scheme:
A kind of novel structure based on loop network control technology, includes host computer and Ethernet switch, described
Communication connection between host computer and Ethernet switch, it is characterised in that: redundancy annular is equipped with by the Ethernet switch
Network control system, communication connection between the Ethernet switch and redundancy ring networked control system.
A kind of novel structure based on loop network control technology as described above, it is characterised in that the redundancy loop network
Control system includes the CPU there are two redundancy, is equipped with driving/I/O module group and executing agency between the CPU of the redundancy, wherein
The CPU of one redundancy and driving/I/O module group communication connection, the communication connection of the driving/between I/O module group and executing agency, separately
Communication connection between the CPU and executing agency of one redundancy.
A kind of novel structure based on loop network control technology as described above, it is characterised in that the driving/I/O module
Group includes multiple driving/I/O modules, communication connection between adjacent driving/I/O module.
A kind of novel structure based on loop network control technology as described above, it is characterised in that the executing agency includes
There are multiple execution modules, communication connection between adjacent execution module.
In conclusion the utility model compared with the existing technology the beneficial effect is that:
The utility model is by can be with a net on earth, on earth from host computer by the redundancy ring networked control system of Ethernet
