QoS Object (48h)

Category
Extended
Object Description
Quality of Service (QoS) is a general term that is applied to mechanisms used to treat traffic streams with dif-
ferent relative priorities or other delivery characteristics. Standard QoS mechanisms include IEEE 802.1D/Q
(Ethernet frame priority) and Differentiated Services (DiffServ) in the TCP/IP protocol suite.
The QoS Object provides a means to configure certain QoS related behaviors in EtherNet/IP devices.
The object is required for devices that support sending EtherNet/IP messages with nonzero DiffServ code
points (DSCP), or sending EtherNet/IP messages in 802.1Q tagged frames.
