Thank you for you answerjacek d , i know that formal parameters on s7 300 do not include static variables, even i think on s7 1500 is the same, but the UC instrucción only work when the instance DB does not have any variable, the DB is not mark as "Optimized block access" and de fb is mark with "parameter passing via register". The call is done by STL language but it only work if the block called is done in STL otherwise it does not work. You can see this in the image attached. |
