Guidance on Ethernet/IP communication for PF755 drives.

https://literature.rockwellautomation.com/idc/groups/literature/documents/um/750com-um001_-en-p.pdf

The first thing that I am looking for help on is the settings for the Logical Device Properties.

The Emerson terms and the AB terms don’t quite line up.

This is the Properties window that I have in DeltaV the attached word document is the help section in DeltaV that gives some explanation of what it is referring to for each field.

From the AB manual that I found online I believe that the Message Class is Class 1 Implicit, the connection priority seems to be whatever I prefer, same with the Request Packet Interval(ms), and the Connection Type according to the AB manual seems to be multicast.

I have no idea about the rest and I am hoping you can shine some light what they should be.

  

 

The second part of this is the setup of the drive.

Below is a screenshot of the DeviceNet signals that we are sending and receiving to the VFD.

I would like to be able to get all the same signals over Ethernet/IP

Can you help with what parameters in the VFD need to be changed?

 I really appreciate your help with this.

  • You're good on Messaging class and RPI.  Input size should be 32, Output size 8, Input Assembly 1, Output Assembly 2, Configuration Assembly 6 has always worked for me with a Connection Type of Point to Point.

    Signal configuration I've always used full integer words for the Status and Command words to see all of the information and then broken out the words in the mapping to individual bits.

    As with most things Ethernet/IP there are multiple ways to get there but this has worked for me (this is from a demo but was controlling a test drive in our lab).
