where i can measure 5 vdc on board of cpu?

who have the same situation?

hi,

5V can´t be measured. This voltage is just inside the CPU and on the backplane-bus.

where do you measure the 31V?

And what do you mean whit "doesn´t get up"?

Please be more specific. the more we know, the more we can help.

 Hello kormotech,

Why do you say that? LED "DC5V" of the CPU is off?

doesn't gut up it mean that controler have not go online,go start

Hello,

hmmmm try another power supply for test, but it looks like some problem on board circuit. Do you have option send device to some local Siemens supplier for repair? Check also price, maybe better will be buy new device as repair costs...
