Hola Joseze; Los participantes del foro de Siemens provienen de muchos países y hablan muchos idiomas diferentes. Para facilitar nuestros intercambios, hemos elegido el inglés como idioma común. Por favor, escríbanos en inglés en su próxima visita. Hello Joseze; Participants in the Siemens forum come from many countries and speak many different languages. To make our exchanges easier, we have chosen English as a common language. Please, write to us in English on your next visit Is this the link to GET/PUT examples you are refering to? https://support.industry.siemens.com/cs/ge/en/view/82212115 Notice in this link there are 2 GET PUT examples for the S7-300 CPUs, one with Step 7 v5.6, which uses SFB 14 and SFB 15 (PUT/GET), and another that is programmed in Step 7 v16, using PUT and GET instructions. So you have examples for both of your CPUs. IMPORTANT NOTE: GET and PUT are S7 communication functions (which meand they wll work between S7 CPUs, using all native S7 communication links, Profinet, Profibus, MPI...) But they have one special distinction: they are one-sided client/server exchange. You only need to setup a connection on one of the PLCs, not on both,. So choose one of the S7-300 CPUs (the client) to send and receive data to the other partner (the server), declare the partner as "unknown" (but give its address) as shown in the documentation pdf file. Then program the PUT and GET functions only on the client CPU, so it can write to the partner and read from the partner CPU. The rest should be easy... Hope this helps, Daniel Chartier |
