I'm surprised the bacnet industry leaders aren't making more public statements looking for the multi-vendor software package for configuration. Perhaps you can ask some of them at the next ASHRAE meeting that talks about controls. Maybe they can give you some information.
Will do..Sysint...Will do.

Some of the software used for testing and commissioning is:
Get your self a good fast RS485 card and you can connect to any network and interface with any manufacture.
Jeff, I think Freddy is specifically looking for multi-vendor configuration software, not simply a commissioning software. (Like LNS is for Lonworks protocol)
However, thanks for that information.
I'm pretty sure that all that software only lets you see network info such as packets, whois, IP addresses etc. I haven't seen any 'device' specific info when runnning any of that software.
Not exactly. You can get device informational data, read/writes/COV etc... What you don't get that I know of is the ability to configure those devices with those manufacturer's products. It's not like LON in that respect.
However, looking at a device like the Loytec LVIS, it scans the controllers on the network and you can configure the Loytec device with the free configuration software. So, that's a start at least.
That would be correct sysint. I need the multi vendor configuration software to configure all my native Bacnet MSTP sites, including JCI FEC, Andover, Delta, Allerton, Trend, and Reliable.
I am sure all we are waiting on is some more BTL testing to get all of BACnet's benefits.
So basically, you want the programming software for free? Is that your beef against BACnet?

I just looked at a site that has T.A.C. Vista (lon), T.A.C. Invensys I/A (lon) and Trane (lon). Is there a software I can use like LNS or Lonwatcher that will enable me to change and/or add programming to each vendors programmable controllers? Speaking to the onsite technician each system had it's own set of software for programmables.
I was quite surprised that even the two T.A.C. lon systems required individual software to program their "freely" programmable main controllers. He said that the T.A.C. salesman informed him that their next generation of software would have this capability but it would require separate licenses.
I thought I could just show up and start making changes and configuring all the systems, but that doesn't seem the case. It looks like the ASC will be available to configure, but I don't know what I'm going to do with the programmables.
Help me, Obi-Lon Kenobi, you're my only hope..................

Great point. There are only a couple vendors that allow you to have their programming language in a plugin, Distech and Circon (to my knowledge). Circon charges some money but it's available to work in the LNS software you want to use. Distech's is free.
So, I guess you have some options. If you need freely programables working with your network config tool, it's available to you-- which is more than you get with bacnet at this time.
Are freely programmables available with open config tools.---Answer YES
Are ASC controllers available with open config tools.--------Answer YES
Is there a multi-vendor software configuration tool.---------Answer YES
Is the field bus modern and robust?------------------------Answer YES
Highly Scaleable?----------------------------------------Answer YES
Do you need "plugfests" for interoperability?----------------Answer NO
Do you need to worry about network addressing/structure?-Answer NO
Do you need to worry about multi-vendor communication?--Answer NO
Personally, I like the structured SNVT's. They are highly identifiable, and very standard. No need to look into an object to figure out what it may be. It's there, it's available and it works. Further, when I want to use SNVT_switch I've got one variable for display. If I'm using nci_Setpoint I've got 6 in one variable. Makes for economy in dealing with those variables in display. With bacnet you need two objects to convey SNVT_switch and six for nci_Setpoint.
Additionally, I like the fact that in a spec you can drill down to the variable names and types to make a very seamless multi-vendor network. For instance, I can have different AHU programmables getting information from a multi-vendor VAV installation and get the same data and types.... without much work and configure all of it with a single piece of software. That capability is impressive.
I also like that the application of a device is up to the designer, but the communication/data transfer is controlled and rock solid.
bacnet-- has a nice way of AST functionality, particularly on the Supervisory level. Network fieldbus technology is archaic and poor by comparison. However, Tridium has a nice way of AST functionality too..
I wonder how many guys buy their upcoming proprietary chipset and don't complain about it? Not to forget mention of Zigbee and Zwave chips...
