Quality of Service (QoS) ensures that critical data is always sent with high priority. Without QoS, critical data may be lost during transmission if the network is congested.
QoS is commonly supported by managed network switches and by some controlling equipment such as PLC devices, but it is rarely seen in unmanaged switches.
The EDS-2000-EL Series supports QoS by simply flipping a DIP switch without requiring additional configuration, making them ideal for factory automation where optimized data transmission is a must.
