Data communications network for real-time industrial control systems

The advancements in network technologies and the evolution of Internet Things (IoT) have made supporting industrial control systems over probabilistic data networks promising. However, systems’ communication traditional is faced with problems instability feedback poor quality performance due to time-varying propagation delay. This paper presents two approaches that can enable real-time non-deterministic computer allowing system designers take advantage existing infrastructures. first approach based on system-level interaction wires called collaboration network. second implementation virtual local area (VLAN). method allows equipment or IP-based while other computers are connected. Nodes providing services same PortID VLAN switch. minimizes traffic reduces delay IP networks. was modeled simulated using Proteus ISIS software. Two PIC16F877A microcontrollers were used represent nodes. CISCO packet tracer model simulate communications Results indicate use a two-wire collaborative effective but requires an additional alongside main channel. VLAN, therefore, more flexible relies
