DP/ASi Link Advanced I/O Access error or parameter assignment error

Dear All,

I have some strange issue on ASi network when reading Analog input card.

When downloaded the hardware configuration everythings works without problem, but when I disconnect DP/ASi link from DP network and put back the all Analog Input card give me I/O access error and CPU can not read PIW address of equivalent modules. On fiels in DP/ASi Link I have no error and I can read all analog chanels of the modules in local display.

Why this can happen? If I download again the hardware configuration everything cames back without problem.

Thanks in Advance!

i think its common problem by some profibus slave (like asi master , drives, some analog PB slaves etc ) and when you turn off your cabinet for abaut 5 minutes ****in 5 minutes all of the internal capacitor equipments decharged**** it will be fine 

Hello Saeed

This behavior, in my case, was solved by a new .dll file to Step 7 created by development department of Siemens. And later was released a HF for Step 7 including this .dll updated. The problem was during the hardware compilation for the ASi analog modules.
