Network segmentation

It is recommended that all independent systems be separated by virtual networks (VLANs) and prioritized accordingly. The result is the coexistence of multiple systems on a single network without unwanted interference. This setup is especially essential when using LAN-RING switches as a transmission route for the alarm system (I&HAS). This is because alarm systems are very sensitive to delays caused by data transmission over the LAN. The great advantage of LAN-RING switches in such a situation is the possibility of using separate VLANs and priorities for data coming over the LAN and from RS485 buses and other inputs and outputs.
