Hello Path These instructions cannot be nadld by S5 to S7 convertor. You need to convert these manually. You need to use indirect addressing or Pointers. You can search for the same in STEP7 help. Also pl have a look at the following links : /tf/WW/en/Posts/45068 /tf/WW/en/Posts/12597 /tf/WW/en/Posts/45068 /tf/WW/en/Posts/33637 /tf/WW/en/Posts/55488 Cheers Navnag |
