Hello, Translated question,, " Good morning, I have a problem in a CPU 412 -2-PN, all the lights are flashing, including RUN and STOP, I have tried to perform the master reset, but the expected result is not obtained since the stop light is always flashing , what solution can you recommend to normalize it, the program is on the flash card, but in this condition I turn it off I try to start it cold or hot but the lights remain the same when I turn it on, also I cannot connect via ethernet nor by MPI to the control to see the diagnostic bus. See attached image. thank you so much " It seems that the CPU is deffected. If after several trials, you could start CPU, then update FW to latest FW version. If not you don't have other choice, replace the CPU. If you didn't updated FW before, then the FW of this CPU as shown in picture is 6.0.2 which is too old and there are many versions solved lot of problems till version 6.0.7 as stated here: Operating System Update V6 CPU412-2 PN/DP, CPU414-3 PN/DP, CPU414F-3 PN/DP, CPU416-3 PN/DP, CPU 416F-3 PN/DP |
