I have Kepware Ex6 set up as OPC UA client, connects to Igniton as OPC UA server and real time data are coming through. I like to send them to Rockwell tudio5000 V31 platform ( L72 processor) . Looking for help., Thanks.

Hi,

 

Kepware cannot write data directly to a Rockwell Studio 5000 (L72) PLC if it's acting only as an OPC UA client. To send real-time data to the L72 processor, follow these steps:

  1. Add the ControlLogix Ethernet driver in Kepware and configure the IP of the L72 PLC.

  2. Create tags in Kepware that match the structure of the tags in the Studio 5000 project (same tag names and data types).

  3. Use a Link Tag in Kepware to link the incoming OPC UA data (from Ignition) to the ControlLogix tags. This allows you to route data internally within Kepware.

  4. Ensure the PLC program allows external writes (without protections or controller-scoped read-only Tags).

  5. Validate communication by monitoring tag status in both Kepware and Studio 5000.

This setup enables you to pass data from Ignition to Kepware and then to the Rockwell PLC.

 

Thanks,
