Preparing for the 3rd release of the IEC
61131-3 standard.
Since 2006, PLCopen in the person of the Managing Director is an official
liaison of the IEC WG7 TF3 - IEC61131-3 Programming Languages (as well as
the other parts). One of the reasons is to work on the 3rd edition of the
standard. All the work going on in PLCopen, as well as the multiple implementations
and new challenges to cope with, create wishes to change certain sections
and add certain features to the standard.
The work on this started on the kick-off meeting on January
16, 2007, resulting in a rejuvenation of the activities in this Technical
Committee 1 – Standards. During this meeting all proposals as gathered
throughout time at PLCopen were presented and discussed. This meeting was
followed the week after by an IEC WG7 TF3 meeting in Florida, including
proposals from other parties.
A next TC1 standards meeting was held on May 2, 2008. The intent of this meeting
was to agree from a PLCopen member’s
point of view on the proposed changes. These changes will be submitted
to the IEC WG7 TF3 with the request to start the procedure for working on
the 3rd edition of the standard. In effect this means that this new edition
will still take several years to conclude. However, if you see potential
improvements in the current edition, contact PLCopen to add these to our
working list.
