The one thing I find interesting about RSLogix in general (caveat: I only have very limited experience with RSLogix 500 / 5000; if I do anything nowadays, it's in the micro series using RSLogix Micro Starter Lite)... they do have some limited notion of version control inside the application itself, though it seems rudimentary to me. This could prove to be helpful or extremely annoying, since even when I connect to a PLC and go online, just to reset the RTC, it still prompts me to save again (even though nothing changed, other than the processor state). You may also find this link on stackexchange helpful: http://programmers.stackexchange.com/questions/102487/are-there-realistic-useful-solutions-for-source-control-for-ladder-logic-program As Randall noted, L5K is just text, and RSLogix 5000 uses it, according to this post. It may work okay. --Doug -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
