Calling a FB with a indirect DB associated

Morning,
I'm trying to write something like this in AWL

CALL FB1, DB [#AUX]

it is possible? what data type must be AUX?

Thank you all

Hi alvconsan,

Try to define AUX like type INT ,

And on the AWL code:

CALL VARIANT_TO_DB_ANY

This will return a XXX : DB_DYN that will give you the possibility to call :

FB10, XXXX

Hello, I don't think this is possible because the DB is related to the FB to the point that the interface parameters and even Time Stamp must coincide, if the timestamp is different you get an error.

Maybe I'm wrong and this is possible but I have never seen it done.

You may try to use some Global DBs and open them inside FC or FB, there you can dynamically address the DBs with OPN instruction.

Regards.

Rescobeco; it has sense to me, I think the correct way is doing a FC that can manage the DB , a "fake" FB (at least, in my case).

This FC must be able to OPN the corresponding DB by an Auxiliar input 

thanks!

 Hello.

If I recall correctly, the format is:

OPN    DB [#AUX] // open DB indirectly
UC     FB1       // unconditional call
