One TP270 in the MPI network is connected and disconnected repeatly every 2~10 seconds. Please see the attached. Thank you. Attachment MPI.zip (822 Downloads)

If so It might be a Busparameter problem that could only be solved if you have all HW Configs of the whole system in one Project. Sadly the Busparameters of MPI are not adjustable from STEP7 itself so you will have to allow STEP7 to do so. ... and don't forget to stay calm. [;)]

I tried to integrate all PLCs and TPs(ProTool project)in one Step7 project and download from this project to the TPs then all the nodes commnunicate eath other correctly. The point is the step7 project and ProTool project should be integrated in one Step7 project. Thank you.
