Hello AnKa; Palo-PLC has provided hints on the S7 side. Information on the 750-891 can be downloaded from the Wago website, including the 750-891 manual that you should definitively consult to program this project. https://www.wago.com/global/plcs-%E2%80%93-controllers/controller-modbus-tcp/p/750-891 Below is a screenshot from the suggested manual: Wago still uses the terms "master" and "slave" generally reserved for Modbus RTU, whereas when discussing Modbus TCP Siemens follows the standard designations "client" and "server". Basically, the 750-891 is designed to act as a server (slave), in which case the S7-1500 must act as client over Modbus TCP, using function MB_CLIENT. If necessary, you could reprogram the 750-891 using Codesys to act as a client. You could always look this up if needed, but it would be simpler to use the Wago as server. Hope this helps, Daniel Chartier |
