I have looked at both of these a few months ago. beremiz
was a proposal to create some open source infrastructure
around the the mat tools. As far as I know there is nothing
more to it than what appears on the website.
Mat is dated now it appears that it was created from some
of the early drafts of the IEC 1131. The feature set is both
a sub and super set of the standardized IEC61131.
IEC61131 contains a grammar for the language parts.
I wrote a quick grammar parser for a project and
then used the standards grammar to create a IEC61131
to C translator. This is not very hard to do and might be
an approach that could be used to create Linux PLC
tools. There are a few commercial tools that have a similar
approach.
IEC61499 should be looked at as well for any serious
attempt to create PLC tools
Not open source but the Oats PLC project is worth looking at.

Well, there is 'The Puffin Projects' at http://www.puffinplc.org
Don't know if it is very active though.

Quite a few PLC's have some version of ARM inside, so it might be doable.
But Why?

I'm sure it can be done, and probably a number already have
Linux buried inside them.
The problem would be getting enough info on the HW, which tends to be
quite custom.
Of more practical interest, may be 'the bigger picture', where
google finds this :
"Beremiz, a Free and Open Source Automation IDE for IEC 61131-3 PLCopen
XML and CANopen"
http://www.beremiz.org/
and most of this (as you'd expect) seems to run under Linux.
Some info here http://sourceforge.net/projects/beremiz/
but it looks relatively quiet.
and here is the IEC to C compiler
http://mat.sourceforge.net/
Not many links on the PLCOpen Editor ?

Has anyone ever tried to port Linux or uCLinux to a modern PLC?
Interested to see if it can be done.
Thanks,
