10 Description of important program elements

10.1 Program structure

The core functions of the standard “flying saw” application are sub-divided

into two sections

• Declaration section

•

Instruction section

All of the interfaces, constants, instance data and multi-instance of the

function blocks called from the block are described in the

Declaration

section

. Er besteht aus der Unit FS_Var.

All program instructions of the code that can be run are provided in the

Instruction section. This Section is sub-divided into four units.

• FS_TEMPL with the "FlyingSaw FB“.

• FS_PMIPO with the print mark sensing and the ipo-synchronous

functions.

• FS_SPB with the FBs to manage the synchronous positions in the

SyncPo buffer

10.2 Declaration part FS_Var

The structure of all of the data required for the FlyingSaw FB is saved in the

unit FS_Var. Instances will be the data in the user unit SAP_Var. When

required, in this unit, this data area can also be instantiated several times

so that the FlySaw FB can also be called for several flying saws within one

project.
