Content	Appendix 27.2 Memory Areas of S7 CPUs Programming with STEP 7 Manual, 05/2010, A5E02789666-01 575 Address Area Access via Units of Following Size S7 Notation (IEC) Description Data block, opened with OPN DB : DB Data blocks contain information for the program. They can be defined for general use by all logic blocks (shared DBs) or they are assigned to a specific FB or SFB (instance DB). Data bit DBX Data byte DBB Data word DBW Data double word DBD Data block, opened with OPN DI : DI Data bit DIX Data byte DIB Data word DIW Data block Data double word DID Local data bit L This area contains the temporary data of a block while the block is being executed. The L stack also provides memory for transferring block parameters and for recording interim results from Ladder Logic networks. Local data byte LB Local data word LW Local data Local data double word LD Peripheral input byte PIB The peripheral input and output areas allow direct access to central and distributed input and output modules (DP). Peripheral input word PIW Peripheral (I/O) area: inputs Peripheral input double word PID Peripheral output byte PQB Peripheral output word PQW Peripheral (I/O) area: outputs Peripheral output double word PQD Refer to the following CPU manuals or instruction lists for information on which address areas are possible for your CPU: • S7-300 Programmable Controller, Hardware and Installation Manual • S7-400, M7-400 Programmable Controllers, Module Specifications Reference Manual • S7-300 Programmable Controller, Instruction List • S7-400 Programmable Controller, Reference Guide
