Сhanel diagnostic AI 8xU/I/RTD/TC ST (6ES7 531-7KF00-0AB0)

My configuration:

Central rack:

CPU 1511C-1 PN (6ES7 511-1CK00-0AB0)

AI 8xU/I/RTD/TC ST (6ES7 531-7KF00-0AB0)

PROFINET IO:

IM 155-5 PN ST (6ES7 155-5AA00-0AB0)

AI 8xU/I/RTD/TC ST (6ES7 531-7KF00-0AB0)

I read diagnostic information about fault channel (Wire break,Overflow,etc.) from distributed module AI 8xU/I/RTD/TC ST (6ES7 531-7KF00-0AB0) in PROFINET IO. I use RDREC with INDEX parameter W#16#800A.

How can i read this diagnostic information from module AI 8xU/I/RTD/TC ST (6ES7 531-7KF00-0AB0) in central rack? RDREC return error “Data record not known in module” with INDEX parameter W#16#800A for module in central rack. AI modules identical.

Only High feature module gives you channel level diagnostic.

The post right above yours has a link ( https://support.industry.siemens.com/cs/ww/en/view/98210758 ) which does that.

I would like to know if I can enable the diagnostics via user program?
