Hello akhbar_torkashwand; Step 7 v5.x has a quirk about peripheral addressing: you cannot use a VAT table to write to PIW, and you can't monitor a PQW directly. You can read a PIW and write to a PQW. The workaround for a PQW is to add a program line in whic you move the PQW value to a MW regster, for example), and monitor that value. See this discussion (among others): https://support.industry.siemens.com/forum/ca/en/posts/pqw-shown-cross/151333 Hope this helps, Daniel Chartier |
