Be aware, when using allen bradley. Next years hardware won't be compatable, with this years. You will need to upgrade your software every year & it will cost real $'s!!! the panel builder is outdated & unneccesarialy complicated. Everything is around 2x more money. look @ here. There are many choices for good stuff.
