6-10 Explicit Messaging on DeviceNet™
• Service Type
The pull down menu has several options, however only the Get
Attribute Single is used for this example.
The Class, Instance, and Attribute define the actual information
being requested. Additional configurations of these parameters
can be found in Appendix B.
•Class
In this example the value is “F”
• Instance
In this example the value is “104”
• Attribute
In this example the value is “1”
After the above information has been entered, click on the
communication tab.
•Path
The path will define the route the message will take to get to the
device it is intended for. In this example the path is Scanner,2,4;
where scanner is the name of the 1756-DNB in the rack, 2
represents the DeviceNet port, and 4 represents the physical node
address of the ArmorStart.
