Profinet io latency
WebJul 26, 2024 · PROFINET is an Industrial Ethernet solution. It is a communication protocol to exchange data between controllers and devices. Controllers can be PLCs, DCSs, or PACs. Devices can be I/O blocks, vision systems, RFID readers, drives, process instruments, proxies, or even other controllers. WebMay 30, 2024 · PROFINET supports many topologies: star, tree, line, ring, wired, and wireless. When using line topology remember that each device includes a switch which will introduce a small amount of latency. Placing a bandwidth-intensive device at the end of the line could result in excess bandwidth issues on the line.
