hi SdSady, first scan is not the solution. When there is a positive edge on REQ it will read(GET) once or write(PUT)once. For updating the values continuosly use clock marker. See following FAQ to see how it work in TIA. It is almost the same. But in this FAQ there is a sequencing to read/write more than 160Byte per request. How do you program the "GET" and "PUT" instructions in the user program of the SIMATIC S7-1200 CPU in order to transfer more than 160 bytes of data?hope this helps,regards, |

hi SDSady, As you can see in following manual, page 97, the S7-300 with CP343-1-Lean can only be Server for the S7-1200. So you have to establish connection as before(see the first FAQ), but use PUT/GET only on S7-1200-side. CPU-CPU Communication with SIMATIC Controllershope this helps, regards, |

Dear MOP Hi First of all I want to thank to you for your kind attention and above replies. I have the same Problem, I've done all of the Configuration, and I attached my project. But the status word and error in put/get function in set to one, on both side. and I don't know how to solve the problem. there exist another ambiguity when I'm doing the configuration. I'm not sure that how to config the S7_connection on both side. I mean is it neccessary to config the S7_connection that exist in put/ get Properties tap for both side? ( I should mention that in the attached project just I have done the configuration for P1 and stat1 PLCs, But i face with some errors.) That will be grate to help me more to solve this problem.
