No need for Modbus. EBPro has full symbolic support for Codesys as their devices can run Codesys as well.
In your Codesys project, you’ll need to add a Symbol Configuration. Build the project. Then select which vars you want added to the config. Click save and the file will be generated.
In your EBPro project, add a device “CODESYS V3 (Ethernet)”. Under settings add your Codesys PLC IP address, port 1740, protocol V3 UDP/IP, source port no. 1742. Add PLC username and password.
Then click “Import Tags”, two char per word and navigate to the location your Codesys project is stored. Open the XML file in that location and your variables will import into your EBPro project.
