A specific ANY parameter must now bechosen from a selection list for transfer to another FB (FC). This can only be done by meansof an ANY in VAR_TEMP. 1 to 4 can be set in parameter "WhichAny" in order to select Addr1to Addr4.NoteAddress register AR2 is used in the block. However, this address register AR2 is also usedfor multiinstance DBs. For this reason, this FB should not be declared as multi-instance DB.FUNCTIONBLOCK FB100CODE_VERSION1 //starting from STEP 7 Version 2 fordeactivating the//multi-instance DBP3: Basic PLC program for SINUMERIK 840D sl13.19 Programming tips with STEP 7Basic Functions1070 Function Manual, 01/2015, 6FC5397-0BP40-5BA2
