How to directly communicate with a Rockwell Kinetix 300 Ethernet/IP Servo Drive with LabVIEW using Ethernet/IP protocol

Highlighted

Hello,

 

I have a Rockwell Kinetix 300 Ethernet/IP Servo drive and I would like to communicate with it using LabVIEW through Ethernet/IP protocol. I've being using Ethernet/IP protocol on other applications to communicate with ControlLogix PLCs with no problem. But now I would like to communicate with a Kinetix Servo Drive in a way I don't have to use Rockwell PLC to control it.

 

Also I would like to communicate with a Frequency Inverster Model Power Flex 400 also from Rockwell.

 

I'm using the following Ethernet/IP Driver provided by NI.

Does anyone have any example or ideas for this communication?

 

Thanks and regards!

Hi Luciano,

 

From my experience with Servo Drives, they typically are Adapters only.  Additionally, the EtherNet/IP driver that NI provides is adapter only.  With this in mind, we will be unable to communicate using Implicit (I/O) Messaging because we will not have a Scanner to initiate the connection.  You will need to use explicit messaging to communicate to the servo.  I would recommend taking a look at the Access Assembly Instance Data (Explicit).vi and Access Identity Attribute (Explicit).vi for getting started.  You can find this in the example finder, Hardware Input and Output » NI-Industrial Communications » EtherNet/IP » EtherNet/IP Adapter.lvproj.
