Industrial automation programming

[Shano]

In regards to programmable logic controllers (like http://ab.rockwellautomation.com/Programmable-Controllers or http://www.schneider-electric.com/en/product-category/3900-pac--plc---other-controllers) ladder, function block, and structured text are commonly used programming methods. As far as I have seen these are always proprietary languages, albeit they can be very similar.

Does anyone know of existing or future efforts to standardise this like c, Java, html or many other programming languages are on PC's. Maybe this has to do with the fact that each manufacturer produces their own hardware, and this prevents a standard language being developed.

ladder, function block, and structured text are commonly used programming methods.

Ladder, function block, and structured text are the standard. The current standard defines data types, how a program should be structured, and general design principals to keep in mind. If you looked at the software used to program the linked unit, you would have found that it is IEC 61131-3 compliant.
