Altran. Ethernet adoption continues to grow in industrial communication networks due to ever-increasing demand for connectivity, automation and speed. Legacy industrial communication networks adopted multiple different technologies such as BACNet, BATibus, CANBUS, FL-Bus, ModBus, ProfiBus, etc which were developed to meet needs in specific deployments. Often, different applications had different requirements. For example, video surveillance requires large bandwidth but is tolerant to loss and delay, while process control requires lower bandwidth but must work in real-time.
