14.2.2
Quality of Service (QoS) Object (72 / 0x48)
The "Quality of Service (QoS) Object" enables different classifications and prioritisations of the data
packets for EtherNet/IP communication. For this purpose, the EtherNet/IP messages are marked
with "802.1Q tags" and "Differentiated Services Codepoints" (DSCP).
Class attributes
Instance attributes
The instance attributes act independently of each other.
The DSCP values are used for the IP headers.
Irrespective of this, VLAN tagging can be activated in addition (
= 1).
The VLAN ID of Lenze devices is ’0’.
The VLAN priority results from the DSCP values configured.
Changes in the attribute values will only take effect after a reset of the device ("power off/on" or
"type 0 reset").
