A Kind of Communication Simulation System for WorldFIP Field Intelligent Control Network

Simulation of communication system in control network plays important role in modern industrial production and can be used in various application. Based on development of WorldFIP field intelligent control network, a kind of communication simulation system was designed and implemented. Simulation principle and implementation methods for data communication in the network were presented. Design and implementation for simulation of network scheduler, intelligent nodes and WorldFIP network communication based on OOP and multi-thread methods were presented in detail. Visual and multi-layered HMI for the simulation system was designed. Techniques in OOP were fully used in design with VC.NET as principle programming language. Complete simulation of WorldFIP communication network and field intelligent nodes was implemented. Operational practice showed the simulation system was stable in operation, good in flexibility and portability, which showed good practicability.
