This free software is three programming packages in one.įirst and foremost, this is the software package you use to program Rockwell's Micro800 family of programmable controllers.īut it also contains the Allen-Bradley PanelView Component programming software, as well as a new editor to configure Rockwell Automation drives, including the new PowerFlex 525. Below I’ll highlight those which I believe are the most useful:ġ) Connected Components Workbench (CCW) free programming software for the Micro800, PowerFlex, and PanelView Component: We’ll start at the Rockwell Software Downloads page’s “ Free Downloads” link, where several packages are available. However, RA does make several software packages available free of charge, and I'll detail those over the next two days.Ĭlick here for the second part of this article Learning the ins and outs of the particular implementation can be a bit challenging, but it can pay off, especially on large projects.Rockwell Automation has a reputation of charging for their PLC programming software, and that's true for most of the packages that program their Programmable Controllers. The PLC screams because it is only solving the code corresponding to the part of the process that's active, and on-line debugging was never easier (brings you to the exact code that's hung-up), at least in the implementation I was using. I've found Sequential Function Charts to be the perfect fit for highly sequential processes. Communication tasks tend to be well suited for this.įinally, keep SFC in mind. It is excellent for dealing with arrays of data and anything you'd image would be easy in BASIC (it's actually quite PASCAL like). I'd recommend keeping Structured Text on your list of requirements. The best solutions are usually a combination.
Using all FB or all ladder will likely produce some cumbersome code somewhere. Implementations can vary greatly.Īlso, good programming practices will lead you to use multiple languages for different functions. Keep in mind that even if all your selections are IEC 61131-3 compliant, they won't necessarily program the same. They did have the first PLC with FB that I ever saw, dating back into the 80's. Don't forget about Reliance AutoMax! Oh wait, that's been discontinued.
