[?]: Replacing CPU S5-95F (6ES5 095-8FB01) ERROR

[hanhdong162]

Dear all!

I have a system to comprise two CPU 95F (6ES5 095-8FB01 Version 3) which are connected via a fiber optic link. They are normal operating.
But When I replace a new CPU 95F (6ES5 095-8FB01 Version 6) for a old CPU (6ES5 095-8FB01 Version 3).

Result: System error ( led DIAGN + led STOP).

After I install again CPU 95F (6ES5 095-8FB01 Version 3) -> System OK.
I don't know the system to comprise a CPU 95F (6ES5 095-8FB01 Version 3) and a CPU 95F (6ES5 095-8FB01 Version 6) which is not ok.
Please help me! Thanks a lot.

Hi,

do you change only one CPU or both?
Both of the CPUs must have the same Version!

ANd I am afraid it's not possible to make update by yourself. Let's say if you have only one CPU higher version, to update the other to the same version. Contact with Siemens.

Best regards,
