Today we see a minor update of PLCEdit - Version 2.2.1. It comes with some
bug fixes and also some nice to have features. Implementations of bigger key
features will not placed this year, maybe. So, also the support of OpenPCS is
not yet included as separate entry in the open and save dialogs.

Ok, what’s changed in v2.2.1?
First of all the session manager can now redirected to a user defined path.
Use the Default button at the preferences dialog if any problem occurs with
the session manager or the selected path.
Next PLCEdit contains now an update function to inform about updates of
the application.
I tried again to fix the tab/file list bug which occurs by saving a file if some
more files are opened.

After a couple of month I proudly present the new major version of
PLCEdit. Version 2.2.0 comes with a lot of new features and got some
good enhancements under the surface.

The new key features are:
- support for Mitsubishi MELSFOT IEC files
- the function block call model converter

Next the support for infoteam’s OpenPCS has started. First files
of OpenPCS will be accepted as plain text POUs. Later seperated
entries in the file open and save dialogs will be added. The sources
are very clean, so there is only something to do regarding the file
extension management in PLCEdit.

I know, I said we will see a new version until end of October. Now we’ve
mid of December. I’m sorry but I had a joyous occasion in private.
And next I’ve found some problems in using the beediff source for the file
differencing function. I think I have to rewrite a lot of routines to hold the
promise „never create any registry entries“ and to make the differencing
really work.

So, for the moment I’ve canceled the file differencing function and will only
have a look to the function block call conversion functionality and the new
Mitsubishi Melsoft support.
Hopefully I’m able to release version 2.2.0 during the next week or better
before the new year is there...

The release v2.1.2 is nearly two and a half month old and during the last
time PLCEdit got some changes according to the announced ToDo list.
But the work would take a few month in addition if we want to leave the
list unchanged. The current feature improvements have reached a status
which allows a speedy release. So, what are the selected features?

- file comparision and differencing utility:
  a dialog window which shows two POUs side by side with in
  color highlighted differences; implemented as context menu
  of each page; comes with optional file open dialog
- function block call conversion:
  enhanced POU compatibility by converting function block calls
  into the appointed IDE call model; can be used as setting for
  the file save routines and as option for the batch processing
- support for Mitsubishi MELSOFT:
  support for .asc export files; supported CONFIGURATION files/sections
- updates:
  enhanced support of TYPE definitions;
  FUNCTION dialog with user defined data types

The upcomming release will not yet include the PLCOpen XML support.
The implementation takes to much time and would delay the release
until 2010.
For now there must be some points fixed regarding the file diff utility.
So, I hope we have 2.2.0 ready this month.
