ControlLogix Server and Client

[Edward_Tatsoft]

Hello,

We are trying to communicate a Allen-Bradley ControlLogix Ethernet with a Allen-Bradley ControlLogix Server Ethernet but without success, could you provide us an project example or give us some ideas of how to do that?

We are using a ControlLogix running both Master and Slave in the same computer, and what we did were:

1 - Create a Allen-Bradley ControlLogix Server Ethernet, create a LogixAddress and create an item pointing to the LogixAddress.
2 - Create a Allen-Bradley ControlLogix Ethernet and set to connect to my computer IP. Create an item pointing to the LogixAddress.
3 - Run the OPC Quick Client and we see that the Master tag has quality bad, follow image:

Best Regards, Eduardo.

Hello Eduardo, 

Thanks for posting. Unfortunately, it is actually the case that the ControlLogix Client (Master) driver and the ControlLogix Server (Slave) driver cannot be used (connected) together to exchange data. The services that are supported by the Client driver are different than the services supported by the Server driver. The Server driver is meant to be used exclusively with physical Logix PLCs or SoftLogix PLCs using CIP Data Table Writes and Reads. 

I'm sorry to deliver the news. Please feel free to reply here or write to presales.support@kepware.com if you'd like to discuss more about your project goals.

Thanks, 
Sam
