Hello, suppose you have a function with the input "IN_Variable" of data type POINTER. When call you assign your variable symbolically. Inside the code is to be: L P##IN_Variable LAR2 L W [AR2,P#0.0] // DB number T #w_DBnr L D [AR2,P#2.0] // bit pointer T #dw_Pointer if you want to immediately use it, then LAR2 OPN DB [#w_DBnr] L D [AR2,P#0.0] T LD 0 Regards Sydney addition: fordetailed information look to the Step7 online help for - POINTER Parameter Type - Area-Crossing Register Indirect Addressing In the attachment is description what the Address registeras well as the 32-bit pointercontains AttachmentAddress registers.pdf (526 Downloads) |
