Can any 61131-3 editors compiled image downloaded to any vendors softPLC software ? Is there any standard format for the compiled image of a 61131-3 editor and the way it should be deciphered in SoftPLC?
Thanks and rgds

First, you need to realize that softPLC is actually a brand name, not a generic term. So I would suspect that softPLC's compiler will indeed make an image that works on softPLC's software. They are based in Texas. If you need some contact info, let me know offlist and I can give it to you. I have a card somewhere.....

You are probably asking if any 61131-3 compiler can load an image on any PC based logic controller.

The answer is no. The format of the editor does not dictate the algorithms that do the solving. If this were mandated, then you would be
required to only have a single hardware platform. Different processors have different capabilities that are taken advantage of in different ways.

Hi,

Short answer I believe is no.

PLCOpen ( "http://www.plcopen.org/":http://www.plcopen.org/ ) came up with a standard file format to allow for program exchange between different 61131-3 compiant editors but very few companies took up the idea (only 2 are listed on the PLCOpen web
site). PLCOpen now seem to be looking at an XML format to achieve the something similar.

Note that even this level of compatibility is only about source file compatibility and not compiled images.

Alas. The standard does not deal with cross-vendor compatibility. OpenPLC ( "openplc.com":http://www.openplc.com ) tried to solve the problem... Don't aware of the result... (No way, but new standard, IMO)

PLCopen ( "plcopen.org":http://www.plcopen.org ) is working on a cross reusability specification to allow for cross pollination of source code.
Structured Text (statement list) and instruction list are cut and paste assuming that there is no deviation from the standard. Ladder is more difficult, and is being generated as a specification.
Function blocks as blocks can be exported using a common platform, and again is being worked on.

There will be nothing that will take a program from x and convert to y totally. Portions yes.

Keep on the plcopen website for updates
