Dear PISCEAN, I already gone through this thread before publishing my thread. My requirement is to collect few PLC variables and put it into SIEMENS S7-1200 PLC , by this I want to publish this data on main server for analysis purpose.Basically I want to communicate with PLC(314/515/317) present in NCU with profibus communication between NCU & S7-1200 PLC. Just like we do PLC to PLC communication over profibus, by same way I wanted to communicatew with PLC present in NCU. Awaiting reply. |

840D powerline and S7-1200 are not in the same generation of Siemens production. at least I did not try to make communication between them. But I am sure and really did 840D PL via profibus port to connected S7-300 DP stations. I did not check but you can try to connect S7-1200 system vis profibus interface module to 840D PL. (the problem will be you can only exchange data by shared data ares, by load/trtansfer instruction. Not like possible there are some macro (FBxx) ready to use) then from S7-1200 you use profinet to communicate whatever you want. I think you need HW GSD, and you can reference the following link or search more information in this forum branch S7-1200 S7-1200 profibus master to cnc machine?PS: S7-300 has profinet function as well |
