Connecting to ABB RETA-01 with Ethernet IP

I am trying to connect to an ABB DCS800 drive controller through a RETA-01 communications module using Ethernet/IP.


I am getting the error "Unable to connect to the network path specified". I am able to ping the ip address of the module in the command window so I know the ip address is good.


I am new to Ethernet/IP as it was just suggested to me a couple of weeks ago to use vs modbus/TCP as being easier/better to work with. Working in LV2011 and using the Get/Set Attribute vi's in the toolkit.


Any suggestions or help/direction would be appreciated.

Hi Craig, 


You should probably check to see if your internet/IP driver is up-to-date and compadible with your controller and LabVIEW 2011 as well as the controller's firmware. I would also recommend using MODBUS I/O. You will need to figure out which registers to use. ABB should be able to help you figure that out. This is needed to set up shared variables used to control the interfacing communication protocol between LabVIEW and the modbus I/O Server.
