Study on a new intelligent PLC with switch management

摘要

This paper has a study on a new intelligent programmable logic controller based on industrial Ethernet (IPLCbIE). It proposes a complete solution for the target segment: MMM, WWW, F&B, medium hydro power. The scopes of the solution discussed in this paper are the process and field part of the IPLCblE architecture. For the process part the scope of our design includes the controllers, the engineering software tools (Unity Pro) and the interfaces with the other equipment of this level, typically other controllers or tools like asset management, SCADA or OPC server. Safety and HSBY controllers are also part of our design. For the field part, the scope of our program includes the remote I/Os and the interfaces with the other equipment of this level, typically distributed I/Os and devices. In this paper, we make a study on the design of the controller. It includes the system architecture of IPLCblE, the application of network module. And it focuses on the discussion of design for the kernel module of the PLC - network module NOC. Our design also includes the interfaces with the operation and management tools. The hardware design is especially introduced in detail in the paper.
