Usability is improved.
Self-diagnostic capability: POWERLINK provides a diagnostic-specific bandwidth that, unlike other systems, is not available for any other purpose, allowing access to field-level remote diagnostics and maintenance. The SDM system and the microcomputer monitoring system can be easily connected.
Synchronization characteristics: the power link has a very key characteristic that cross communication between nodes is completely feasible, all nodes on the network can receive information of any sender as in the broadcast principle, and the data does not need to pass through a Master, so that the load on the Master can be reduced, and the data transmission speed is improved at the same time.
Future testability: centralized control interlocking and cloud interlocking systems have been studied and released abroad; these systems are all characterized by a centralized computation of the business logic, and control based on distributed control over IP ethernet. The key here is the secure real-time ethernet control protocol. POWERLINK has natural advantages in these respects.
