One thing I found interesting is their implementation of the IEC 61131 languages allowed automatic conversion between the languages (with some limitations).Ī ladder logic routine could be displayed and edited as instruction list, for example. Their Machine Expert (formerly known as SoMachine) comes in a free version (“Basic”) that’s good enough to service an existing machine. It’s now owned by Schneider Electric, and continues to make PLCs. Modicon is known as one of the first PLC manufacturers.
This environment is a little closer to some other Visual Studio based applications, so there’s still some transfer to other brands. It’s laid out differently than typical AB environments, so experience with CCW isn’t likely to translate into RS5000 or RSLogix500. The biggest downside for education is more advanced programming features are not available in the free version.Ī final thought here: This is made by Allen Bradley, but it’s based on Microsoft Visual Studio. The latest version (v12) includes simulation in the free version as well. CCW only supports three of the IEC 61131 languages, but they’re the right three in my opinion (LD, ST, FBD).
