Your structures are incorrect.
You have:-
ID :BYTE;
S_data_type:BYTE;
S_length:BYTE;
S_DB_nr : INT;
S_speicherbereich:DWORD;
S_Byte_ptr_msb:BYTE;
S_Byte_ptr_lsb:WORD;

The structure should be:-
ID (1 byte)
Data type (1 byte)
Length (2 bytes)
DB Number (2 bytes)
Area ponter (4 bytes)
Making a total of 10 bytes.
You have used both speicherbereich and Byte_ptr_msb / Byte_ptr_lsb.
You have also set speicherbereich incorrectly. You have set it to dw#16#84 which equates to dw#16#00000084.
This is nonsense as your ANY pointer is 14 bytes in length and not 10 as it should be. You should use one or the other.

If you just want the data into the start of the DB you can just use speicherbereich and set it to DW#16#84000000 and delete the S_Byte_ptr_msb and S_Byte_ptr_lsb elements.

If you want to use other addresses in the DB other than 0, then you will need a different structure.
Delete the speicherbereich and add these in place of it:-
MemoryArea:Byte
S_Byte_ptr_msb:BYTE;
S_Byte_ptr_lsb:WORD;
Then set MemoryArea to B#16#84 and then set S_Byte_ptr_lsb to the byte address (0 = byte 0, 8 = byte 1, 16 = byte 2 etc.). Leave S_Byte_ptr_msb at 0 for now as this only comes into play when you want to access DB addresses greater then 8192 bytes.

Basically the area pointer is in the format:-
10000ZZZ 00000YYY YYYYYYYY YYYYYXXX
Where ZZZ is the perand area (in your case 4 (2#100) = Global data block).
YYY YYYYYYYY YYYYY is the byte address
XXX is the bit address (this MUST always be 0 when using BLKMOV as BLKMOV can only move full bytes and byte alligned boundaries).
So in your case 2#10000ZZZ = 2#100000100 = 16#84.
The 00000YYY YYYYYYYY YYYYYXXX would be your byte address bit shifted left by 3 bit positions. For example if you wanted to access byte 10 it would be dw#2#0000 0000 0000 0000 0000 0000 0000 1010 bit shifted ledt by 3 = dw#2#0000 0000 0000 0000 0000 0000 0101 0000 = 80 (or 16#50). Note that this 10 * 8 as there are 8 bits in a byte.

 hi..

The structure has been defined.

The program is running in one project coorectly.

But in my project I am getting the same err.

Please suggest
