Hello everyone. I faced the same problem. CPP319-3PN/DP can not communicat to PC at all (MPI, Profibus, Ethernet) all LED flashing, see attached video, and the temperature at cooling unit is too much I supposed so. 1.I check inlet power it is constantly 24V. 2. From visual check every PCB looks good, not any bunt circuits 3. After 2-5 minutes LED flashing, all LED turn off. I think temperature goes to high and processor turns off. As I check all similar topics no one found solution, beside to replace whole CPU with new one [also I did the same:) ]. Depends on my opinion main pcb is damaged, processor is out of its lifetime. I am interested if it is possible to order new PCB from Siemens store, or can someone have that PCB. Also I am ok if someone will send damaged CPU319 for testing ------------------------------------------------------------------------------------------ |
