I have written about IEC for 4 issues. I would like to share a thread from the Automation Control List as an exclamation point to my columns!!
The user is programming in Step 7 (Siemens) . The names have been removed. Be sure to read the very last line. I have always said that IEC 61131 is a great concept, but I don't try to sell it as a silver bullet for automation programming.
I am trying to export a POU but Export function is grayed out. I have tried to right-click on my MAIN (%OB1) block and select Export, but it is grayed out and I cannot figure out what i am doing wrong. I am trying to do this in IEC-1131 mode. Thanks!

IMPORT and EXPORT only work in SIMATIC Mode, Why do you want to use it?

I was hoping to port the logic over to another IEC program editor and reuse the code. It would be a lot easier than retyping the code from scratch.

You can export the logic over as a text file in stl code and then maybe you can import that into your other application.

IEC is a standard, but it's not that standard. :(
The export only exports in a proprietary format anyway.
