Sending a single parameter from PF525 to ML1100

[LURBY 1]

I have a Powerflex 525 communicating with a Micrologix 1100 over Ethernet.  I can start, stop, and control the speed of the drive just fine.  I would also like to read other parameters into the PLC like Current and Fault Code.  How do I send a single parameter that isn't part of the "N41" files?

Explicit Messaging? 

Datalinks?

Explicit messaging.  See page 70 of the user manual for the embedded Ethernet/IP adapter:

The example is for a CompactLogix, but I've seen it done very successfully with a MicroLogix 1400.  I may be able to find an example for you.

The PowerFlex 525 is an Ethernet/IP drive that integrates well with tag-based PLCs.  The MicroLogix 1100 is the older-generation data table-based PLC.  For adapting the PF525 with a Micro1100, you are probably using a MSG CIP messaging protocol?  

I did find this document; Appendix A references Fault Code for the Instance declaration.  http://literature.rockwellautomation.com/idc/groups/literature/documents/at/750com-at001_-en-p.pdf

Thank you.

I am using most of those for the start, stop, and speed commands.

MSG3 and MSG7 are the CIP Generic reads that I do not have,  They look identical aside from where you are putting them (N5 and N15)?  Looks like you are reading the same thing or am I looking at it wrong?  Is it reading parameter 2?

Honestly, I can't answer your question.  That code was written by a colleague who has already left for the day.  I've done messaging to drives before, but from a Logix 5000 PLC, not 500.

Any chance that you could ask him?  Looks like this might be the way to do it but I would love to know what the difference is between those two messages.

 

Thanks

I found this article on AB's site:

(access level: everyone)

 

I'll try to remember to ask him tomorrow when he's in, but I seem to remember him having to do a lot of experimentation to get it to work.
