RSLogix 5000 software supports the ControlLogix architecture, and is the programming software for the Logix5550/55/61/63 controllers. This controller represents the new generation of control products from Allen-Bradley. The RSLogix 5000 package builds on the easy-to-use RSLogix 500 ladder editor to provide a programming environment that takes advantage of the features of the new architecture. RSLogix 5000 is compatible with programs created with any of Rockwell Softwares DOS-based programming packages, as well as with RSLogix 5 and 500.
