Usually you don't have to modify any configs, if the point is visible with all its subpoints in lonmaker, there should be a + sign next to the unvt/scpt/snvt etc. if it is a structured datatype that...

since Plexus, (in my experience) is one of the most forgiving lon platforms, it seems strange that this trouble has come up.
Have you tried upgrading the lns driver in Plexus.
Most time when a...

Most older Dos based software use hardware interrupt calls direct to the ports.
There is a good chance that this will fail under virtual machine and possibly also under the bios of the newer...

UC's are all custom code. No canned program here.
You will need PTS software to upload and look at the code

Anyone know what type of ethernet card the trane BCU requires?
A part number would be helpful.

Yes, don't use frontpage.
Frontpage adds control extensions to its html code that is native only to frontpage.
When you create a website on a commercial server you have to request that frontpage...

A relay is a dry contact and a triac switches voltage via a "triac" (a type of semiconductor).
You cannot hook external voltages directly to a triac output usually, but you can with a relay.

There are a great many small contractors doing good, quality...

Sorry, but I have worked for Honeywell, Siemens and Invensys.
They all have the same attitude...Sweet talk up front, thumb screws later.
Once their proprietary system is in place they will take you...

I don't care how well engineered, installed or maintained it is eventually JCI, Trane, Siemens, TAC etc. will bend you over the barrel...

I have heard this question many times, but, in my opinion the answer is YES!.
Hire some with mechanical, some with electrical and some with computer.
Cross train as necessary.
Nothing sucks more...

If you check out the devices at B&B electronics, stay away from the vlink product line. I have had problems with these devices going to sleep on me and dropping comm.

If you have Siemens TECs then you have a BLN device talking to them.
This could be an MBC, MEC, SCU or FLNC.

I also worked for Siemens for 5 years, I loved the first 3 years and then transferred to another branch. I only lasted 2 years at that branch because of the management and politics of the place....

My philosophy is this:

"If you can't buy the parts and software at Wal-mart, it's proprietary".

simple as that.

Why does it matter?

Controls companies like to see one of two experience paths (preferably both).
1.) Mechanical - like previously posted, preferably in the commercial field. The more equipment you have experience...

This post is old,
I bought one from local rep last year,
They have gone out of business, now I am local rep.

I used to work for ESUSA, they are no longer in business.
They got bought out by JCI.
However, ISA in Louisvill KY repairs Honeywell parts.
Their website doesn't seem to be working right now.

I went through the exact same scenario that you are going through.
I worked at a major University that was building a new medical research building. We had a Siemens system throughout the...

I wish I knew a faster way.

As opposed to say, Siemens blowing up and shutting down all support for the Apogee line?

Is that Indian as in native american? or Indian as in "Gandhi" ?
Not that it matters, because I don't know in either case.

Sorry, there was no software involved.
Customer only had a bacview panel.
advanced functions were done dial-in by the rep.

The TEC's need some intermediate device between the FLN and the BLN such as a FLN controller or SCU or MBC. Given that the Insight is version 3.3 I doubt that there would be an MEC involved since...

I have a customer that I have recently replaced their ALC system with smart controls.

I have had problems in the past with low flow not having enough pressure to move the condensate...

I am installing several sites with smartcontrols right now.
Info on these devices is pretty scarce.
It helps if you have a rep that is working with you.

Signal is a software package designed to interface with the Barber-Coleman network 8000 hardware.
Usually you would have Microzones or Pems as field devices all talking back to a GCM. The signal...

I would recommend the siemens hardware.
Only because it doesnt take any special software to program it.
A PC with an easily fabricated cable and Hyperterminal will do the trick.
The downside is...

All you can really do in this case is comply with the requirements they provide.

A company called "ENFLEX" produces a web based interface to network 8000. It requires the system to have a GCM to interface to.

And then it all goes to hell when the Air balancer gets done with it....lol.

Anybody have any info on this old piece of crap?
I've never heard of it before, but I have unfortunately run into one.

I would tend to agree, however, I came at it from the other side. Being computer/electronics literate and knowing virtually nothing about HVAC/R. The one advantage I found to this was that there...

I have the UV manual in pdf format, I can email it to you.
I wasn't able to find anything on the 2497 or 2342, what equipment are they attached to?

I hope you don't mind my piggybacking onto your post, but Does anyone know of a way to back up a GCM without signal or problock?

You need to consider the light levels in the monitored area, the traffic volume, and the recording method.

For example:
If it's low light, you need a high lux camera.
If the traffic volume is...

Is this Apogee or pre-apogee?

Pre-apogee had an autologoff that had to be disabled as mentioned in the previous post or it would kick you off.
I believe it was ctrl-b that disabled it but I can't...
