New BACnet addenda in public review (3/25 - 5/09)

The announcement is probably buried deep in the email that accumulated while I was away the last couple of weeks, so I just learned that a new set of BACnet addenda have just gone out for public review, beginning March 25th and ending May 9th. These addenda are as follows:
Addendum 135-2008ae, 2nd PR (public review)
- Physical Access Control, Access Door object, new enumerations for Door_Status and Lock_Status properties

Addendum 135-2008ak, 1st PR
- Define explicitly-required ranges for Device Instances and MAC Addresses
- specify 'abort-reason' for specific situations in Clause 5 Transaction State Machines
- Add a Serial_Number property

Addendum 135.1-2008j, 1st PR
Addendum 135.1-2008l, 1st PR
Addendum 135.1-2008m, 1st PR
Addendum 135.1-2008n, 1st PR

- Improve, clarify, revise, generalize, correct, update, replace and add tests

Addendum 135.1-2008k, 1st PR
- Add new manual MS/TP tests
Most of these, obviously, modify the BACnet testing standard, ASHRAE 135.1-2009, and thus are most likely to be of interest to BACnet manufacturers.

This is, possibly, the last opportunity for the public to review and comment on these proposed changes. If no comments are received, public acceptance is assumed and they will be published as additions to the standards. You can review and comment here.
