40.1 FP TOOL Library
The FP TOOL Library contains advanced address, information and copy functions available for all PLCs to
make programming easier. Below please find a selection of these functions. For more detailed information and
examples, see Online help.
!
Program can be adversely effected!
These functions can cause substantial problems by
accessing incorrect memory areas if they are not used
in the sense they were meant for. Especially other
parts of the program can be adversely effected.
Name Function
Addresses Instructions
Adr_Of_Var Address of a variable at the input/output of a FP function
AdrLast_Of_Var Address of a variable at the input/output of a FP function
Adr_Of_VarOffs Address of a variable with offset at the input/output of a FP function
Size Information Instructions
Size_Of_Var Yields the size of a variable in words (with Enable)
Elem_OfArray1D Yields the number of elements in an array (with Enable)
Elem_OfArray2D Yields the number of elements of the 1st and 2nd dimension of an array (with
Enable)
Elem_OfArray3D Yields the number of elements of the 1st, 2nd and 3rd dimension of an array
(with Enable)
Pointer Instructions
GetPointer Provides pointer information
AreaOffs_ToVar Copies the content of an address specified by memory area and address
offset to a variable (with Enable)
Var_ToAreaOffs Copies the value of a variable to an address specified by memory area and
address offset to a variable (with Enable)
Is_AreaDT Yields TRUE if the memory area of a variable is a DT area (with Enable)
Is_AreaFL Yields TRUE if the memory area of a variable is a FL area (with Enable)
AdrDT_Of_Offs DT address from the address offset for the input/output of a FP function
AdrFL_Of_Offs FL address from the address offset for the input/output of a FP function
Additional Copy Instructions
This functions are allowed to be compiled because of the
down-compatibility to lower versions but cannot be selected in
the "Instructions" dialog anymore.
Any16_ToBool16 Replaced from version 5 onwards by the function INT_TO_BOOL16 or
WORD_TO_BOOL16.
Bool16_ToAny16 Replaced from version 5 onwards by the function BOOL16_TO_INT or
BOOL16_TO_WORD.
Any32_ToBool32 Replaced from version 5 onwards by the function DINT_TO_BOOL32 or
DWORD_TO_BOOL32.
Bool32_ToAny32 Replaced from version 5 onwards by the function BOOL32_TO_DINT or
BOOL32_TO_DWORD.
Any16_ToSpecDT Replaced from version 5 onwards by the function INT_TO_SDT or
WORD_TO_SDT.
SpecDT_ToAny16 Replaced from version 5 onwards by the function SDT_TO_INT or
SDT_TO_WORD.
