Hello, There are no Micrologix that you are able to make online program edits to and in the SLC world you must use a 503 or higher to have online programming ability. Hope that this helps. Robert

The MicroLogix, for better or for worse, are built on a processor and firmware platform very similar to the SLC-5/02, which does not support online editing. Jiri Toman in another thread posited a great analysis of how the nonvolatile memory feature of the MicroLogix 1000 prevents it from easily supporting online editing. I think we'll probably see a "MicroLogix 5000" type product for the Micro1500's I/O platform, which will run the ControlLogix execution engine. After all, there's already a "Pak-OC" embedded PC for that hardware platform. Maybe we'll see tiny ControlLogix-type controllers with fixed I/O too. But for the time being, the minimum A-B controller that supports online editing is the 8k version of the SLC-5/03 controller, part number 1747-L531.
