51. E00171227 01 1 3 Editing the Converted Program 7 3 Indirect Addressing Conversion The S5 S7 Converter uses STEP 7 instructions to convert indirect addressing with DO FW and DO DW The instruction sequence generated is generally very extensive since the STEP 5 pointer has to be converted into STEP 7 format and the accumulator contents and the status word must be buffered when doing so If your program contains very frequent indirect addressing then it is worth adapting to the indirect addressing in STEP 7 A substantial amount of memory space can be saved by using appropriate programming techniques The list below explains how the S5 S7 Converter converts indirect addressing in different cases Indirect addressing of timers and counters is converted into memory indirect addressing by using a temporary local data word Indirect addressing of blocks is converted into memory indirect addressing by using a temporary local data word The new block numbers cannot be taken into account during conversion and must therefore be corrected The indirect addressing of addresses is converted by bits and words into register indirect addressing by using the address register ARI and temporary local data as a buffer for the status word STW ACCU 1 and ACCU 2 The instructions are not converted Indirect addressing must be reprogrammed in S7 The instructions must be reprogrammed in S7 For further information on indirect addressing see Sect
