I defined myArray of length 11. But length is  coming 16 after using 

FC1(GetArraySize)->

#size := CountOfElements(IN := #getArray);

OB1->

"GetArraySize"(getArray:="Data_block_1".myArray,size=>"Data_block_1".arraySize);

Split from How to get the size(or length) of an array .

This should do it.

In VAR_TEMP add:-
pARR : ANY;  // DB address ANY pointer - used for accessing DB data
pAnyARR AT pARR :
STRUCT  // Diassembled ANY pointer structure
S7Code : BYTE;  // Code for S7 (fixed at 16#10)
DataType : BYTE;  // Code for data type
Length : INT;  // Repetition factor = Send/receive length
DBNumber : INT;  // Data block Number
MemoryArea     : BYTE;   // Specified memory area = 0x84 = data block
ByteAddressMSB : BYTE;   // Byte address most significant bits
ByteAddressLSB : WORD;   // Byte address least significant bits
END_STRUCT;

In you code add:-
pARR := YourArray.FirstArrayElement; // The ANY pointer must point to the first element in
                                                                    // the array and not just at the array itself

Now the array size can be obtained with pAnyARR.Length and the array element data types can be obtained with pAnyARR.DataType.

 Hi,

If you use CountOfElements function to get the number of elements of an array of bool, the fill elements are also included in the count. (For example, 8 is returned for an ARRAY[0..1] of BOOL).

Turn off "optimized access" on both thye FC and the DB and it should work.

Plus I noticed that you are setting ths pointer up to point to array element 10.
Is this intentional?
Normally you would point the pointer at just the array itself (e.g. "ArraySize".myArray) as this gives you the address of the whole array and not just one element within it.
I cannot say what you have done is incorrect as I cannot see all your code or know what you are trying to acheive.

Thx...Its working now........I dint disable optimization for DB. Its requirement to use ANY pointer. 

I was testing BLKMOV operation. Initially its giving problem. But its also working.

So is there any list of functions for which we need to disable optimization in TIA?

New question published by ossa is split to a separate thread with the subject Using the ANY pointers.
