Hello i have an Fc1 with var-in-out and its data type is struct and call the Fc1 in ob1 after trying to define the address (using DB through pointer) of called fc1 get an error'' Declaration range actual side does not fit the formal declaration range  var_in_out of the formal parameter in'' can any one tell how can define address 

logic in simatic manager

OB1

FC1

in datatype is struct

input data type is bool.

out data type is bool

Hello i have an Fc1 with var-in-out and its data type is struct and call the Fc1 in ob1 after trying to define the address (using DB through pointer) of called fc1 get an error'' Declaration range actual side does not fit the formal declaration range  var_in_out of the formal parameter in'' can any one tell how can define address 

logic in simatic manager

OB1

CALL  FC     1

out:=M0.0

in := P#db1.dbx0.0

FC1

in datatype is struct

input data type is bool.

out data type is bool

A     #in.input

=     #out

it's a bit confusing writing "var-in-out" and then only in resp. out in the code. What about some screenshots showing how it looks like and one of the error.

 Hi,

Istead of:

muhammadali7712

in := P#db1.dbx0.0

Try to add type and lenght:

P#DB1.DBX0.0 BOOL x

where x is the lenght (number of BOOL).

Let me know,

Bye!

Dear please see attached screenshots of logic and trying to find the error and share. thanks

OB1

FC1 

DB1

DEAR I HAVE SHARED SOME SCREENSHOTS OF LOGIC PLEASE SEE MAY BE ITS HELPFUL TO MORE CLEAR .

DB1 DATA TYPE IS BOOL ADDRESS 0.0

I found this article where i think is resolved a problem like your:
