Dear all; I am working on a small project of visualization, i have done the modules mounting and i wired them correctly as shown on the manuels, my program is compiled and tested ith PLC sim. When i powered the rack, the green leds of PM, CPU & communication modules are green, i put CPU on run and it's ok. I loaded the program on the CPU, the loading is done correctly, when i go on line on device view, only the CPU and PM are detected and ok, but all the other modules (I/O and communication ) are not detected. the diagnostic message show me that this module is not accessible. Please help, what's the problem, i am sure that they are correctly mounted, and my configuration in the software is the same as the hardware, what is the solution? My CPU is 315-2 PN/DP, the soft is Tia portal V15, the connection is with profinet with my PC. Do you have any idea how to solve this problem? I'm lookingforward toyour response. Thanks in advance for all ! Best Regards |

If you configured the network topology in topology view, start with first deleting any connections made in topology view. Download the hardware configuration changes and see what happens. This is not the most likely issue, but possibly a factor. Post your diagnostics buffer (you can search in F1-Help or on this support site how to locate and access it) contents and we can help much better.
