¿How to use pointers to DB?

Radastan

I want, in SCL, to point a data in a DB trough a pointer.

Some like DB[x].dw0

¿It is possible?

I findWORD_TO_BLOCK_DB instruction on this forum, but TIA PORTAL show me an "Instruction not recogniced" advice. I try:

WORD_TO_BLOCK_DB(#DB_ADDRESS).DW[#DB_WORD] := #DB_DATA;

Is for a S7-1200 with 3.0 firmware and TIA Portal V11 SP2 Update 4.

SCL for S7-1200 provides instructions for indirect addressing of operands. For more information on the instructions, refer to the "References" chapter:

• POKE - Write memory address
• POKE_BOOL - Write memory bit
• PEEK - Read memory address
• PEEK_BOOL - Read memory bit
• POKE_BLK - Write memory area

SCL for S7-300/400 supports the following functions for indirect addressing:

• Indirect addressing of tags
• Indirect addressing of data blocks
