I´m working on a project that involves 3 CPU 314c-2PN/DP, 2 ET200_SP, one CPU 313C, one 1214 , one IM151-8, as you can see in the picture below. Practically, each CPU is programed by a differnt person, but, with my PLC1, I want to acces some data on that CPUs and bring them to my project, or to write some data on that projects. I don´t know where to start first. I have the 313C(Slave 1 in the picture) connected with Profibus, and I can read and write without any problem, also I can read and write into my ET200_1 and ET200_2 connected by Profinet, also no problems with the Micromaster and the E277. I have problemas to comunicate with the others 314C-2 PN/DP over the Profinet. Tia Portal inserts adicional projects for each CPU I insert in my project. I don´t know if I have to bring all that configuration to my project, or leave them like they appear to be. On the other side, the PLC_2 is connected with a fest CPX Profibus I/O. I hae to insert also all this compenents into my project ? I configure my 314C PLC as a IO Device as shown in image3, but it gives me SF and Bus error. The 1214 and the IM doesn´t have this option, so how con I communicate with this PLC´s? Only with Get and Put instructions? But using the 3142PN/DP it will be normal to operate as a I/O , as a I-Device, but it doesn´t work.. Attachment image1.jpg (137 Downloads)

Until then, get/put is probably the best approach. That is most likely what I would use anyway.
