Whats the scoop with this new super secret protocol. MSTP Bacnet? looks that way by the looks of the comm wire they pulled.

BCU still in play? New BCU equivalent? Legacy support if new supervisory Hardware?

From the looks of it so far the info and pricing....I have been tasked by a prospective sceptical and educated victim...Early synopses is...it appears...it has total lockem in and screw em good intentions all in the name of "open"...... on a mass scale! Is this true?

Bacnet MSTP with new BCU equivalent to replace BCU. More along the lines of NAE or JACE as new front end is ethernet based with web access. I know the new frontend handles lon will check on legacy comm3 and 4.

As qtip said Lon and Bacnet mstp for the unit level. Bacnet ip/web for the front end. Will be web based front end with no legacy support. It will be the eventual replacement of the BCU but first release is limited apps.

BACnet is gonna be the communication protocol of the future, according to ASHRAE, LON was supposed to be. We wil see how it goes.. BTW Bacnet is not Trane's brain child, thank god...

Or was it that CCN was the future, according to Carrier?

BACnet is gonna be the communication protocol of the future...I like some of the concepts of bacnet. However, I hope it fails miserably. The astonishing amount of garbage put out in the name of bacnet is incredible. I hold ASHRAE responsible for their careless disregard of honest information. Certainly I appreciate the fact that ASHRAE is not a worldwide organization.

Bacnet is no solution for heavy node concentration unless they utilize IP. When you get to that, however, there are many viable alternatives. Further, the basic structure of the variables is so bland that some other more descriptive technologies are crowded out by the ASHRAE advertising machine.

So, I don't care if it's Niagara, OPC, or the next tech.... as long as it's not bacnet. Bacnet is a backwards step for the industry. Here we had another protocol with it's own universal commissioning and network tool (among other important features) and the industry works the ASHRAE fools so that they push that fractured bacnet on the market. Definitively backwards.
