Hello everyone,

is there any method how to make DataType instead of DB insatnce for FB?

I have FB for doors (some counters, timers, logic etc...)

With every instance of this FB it creates DB instance - but it's too many DBs so is here any chance / method how to make this DBs as a user defined data type and put it in single DB?

Like timers - i can make DB with IEC_TIMER datatype and use only one DB for all timers in program instead of plenty DBs.

Thanks!

Split from DB instance of FB as datatype.

Hello, How can do the same in S7 for my 400 Series CPU.

 Hello Abhiboss. 

I believe its the same way. 

Make a "parent" FB and call of the other FBs, "child" inside that "parent", declare your "child" FBs on the static portion of declaration table. 

Regards.

Thanks for your reply, but while doing so, when im going to add "child FB" in  the "parent FB" my Child FB instance is not acceptable. (As shown in the image in the red color font)

Find the image for the same, where I had declared "FbDb" in static variable of my parent FB, with its Fb data type like "MinMaxCal" as shown in the image so how can i achieve the same in the simatic manager. The same program is ok with TIA portal commissioning software easily.
