Hello Botic, The Siwarex WP522 module is the correct one for the S7-1515 CPU. The communication between the Siwarex WP522 module and the S7-1515 CPU is handled with the Simatic backplane bus. You can find an example project for TIA Portal on the internet: https://support.industry.siemens.com/cs/ww/en/view/109736579 Modbus TCP/IP can be used, if you: - want to connect directly an HMI-panel to the Siwarex WP522 module OR - would like to communicate with a third party CPU. Modbus RTU can be used, if you: - would like to communicate with a third party CPU. But Modbus TCP/IP and Modbus RTU is NOT used for the communication between the Siwarex WP522 module and the S7-1515 CPU! Best regards Siwarexi |

Hey Siwarexi, Yeah I figured that out after I created the post. I am guilty of the cardinal sin of posting here before RTFM. Thanks for your help, Botic
