dear guys,
please i read many documents about pointers in siemens s7 but i have a conflict in using pointers as i try to write programs but without any result,if you please can you help me to overcome that conflict to be familiar with programing with pointers.let us start with the first conflict
when i write that instruction
L P##ghost //ghost in FB variable declaration table is pointer data type
LAR1 //i know that AR1 here is loaded with the address that will be entered in the actual parameter
my Q is {AR1 is 32 bit reg. and the pointer data is 3 words (48 bit),how can this happens?}
