[?]: A block address reference help

[dspic]

Dear all,
How i can find DB address value which is using or updating the program output such as FC,FB ..etc?


please see the E.g



Here I want to find the address DB121DBX160.0 .
Is it possible to find this value specifically in Simatic manager ?




Then i put a filter 121 but i only get the result down below



How i can find the data source of this address or data user of this address?

all help appreciated .

we dont know the program but if it writes there indirectly (seems so) you can not find it, you need to read all the program.

If this is updated by some instructions such as indirectly addressing, nothing can do but read related FC & FBs.
