Call example
As far as the time is concerned, the basic program must be executed before other interrupt-
driven user programs. It is, therefore, called first in OB 40.
The following example contains the standard declarations for OB 40 and the call for the
basic program.
ORGANIZATION_BLOCK OB 40
VAR_TEMP
OB40_EV_CLASS : BYTE ;
OB40_STRT_INF : BYTE ;
OB40_PRIORITY : BYTE ;
OB40_OB_NUMBR : BYTE ;
OB40_RESERVED_1 : BYTE ;
OB40_MDL_ID : BYTE ;
OB40_MDL_ADDR : INT ;
OB40_POINT_ADDR : DWORD;
OB40_DATE_TIME : DATE_AND_TIME;
//Assigned to basic program
GP_IRFromNCK : BOOL ;
//Interrupt by NCK for user
GP_TM : BOOL ;
//Tool management
GP_InPosition : ARRAY [1..3] OF BOOL;
//Axis-oriented for positioning,
//Indexing axes, spindles
GP_AuxFunction : ARRAY [1..10] OF BOOL;
//Channel-oriented for auxiliary functions
GP_FMBlock : ARRAY [1..10] OF BOOL;
//Currently not used
//Further local user data may be defined from this point onwards
