Data Block Instructions 5.2 OPN Open a Data Block Format OPN Address Data block type Source address DB, DI 1 to 65535 Description of instruction Status word Example OPN opens a data block as a shared data block or as an instance data block. One shared data block and one instance data block can be open at the same time. BR CC 1 CC 0 OV OS OR STA RLO /FC writes: - - - - - - - - - STL Explanation OPN DB10 //Open data block DB10 as a shared data block. L DBW35 //Load data word 35 of the opened data block into ACCU 1-L. T MW22 //Transfer the content of ACCU 1-L into MW22. OPN DI20 //Open data block DB20 as an instance data block. L DIB12 //Load data byte 12 of the opened instance data block into ACCU 1-L. T DBB37 //Transfer the content of ACCU 1-L to data byte 37 of the opened shared data block. Statement List (STL) for S7-300 and S7-400 Programming 5-2 A5E00706960-01
5.3 CDB Exchange Shared DB and Instance DB Format CDB Description of instruction Status word Data Block Instructions CDB is used to exchange the shared data block and instance data block.
