"the ALC exclusive territory is being pushed by the ALC rep even though the promise was that there would be multiple ALC vendors"
- If your local ALC Rep sucks then ALC will suck. I have to compete...

The WebCTRL version is already out in beta.

Exp = Expansion board #.
chan = channel Exec 6 (Legacy) programs, yes you are correct. 4x = AO, or Pneumatic output
1x = DO, 2x = DI, 3x = AI
Yes there is more to it, but that's all most ever use.

AS a ALC tech I agree with the above to a point. You have older controls, hope they are EXEC B and not EXEC 6. Legacy has more of a learning curve and special tools.

The VPN took care of the DSL IP's. Your right, looking at the project I needed to use BBMD's also.

I've used VPN's were needed. Example: (8) buildings with DSL's and different IP addresses and I provide the routers.

Mostly BBMD's are used on sites were you are given have several static IP's on...

Or 59 devices if it's a legacy UNI/59 in WebCTRL.

Thats was correct back in the day, I left Invensys in 2001. Every time a new tech showed up he would change the entire database...Your bringing back memories. No matter how bad or buggy this lon junk...

Can't imagine a alarm you would miss with APC and SNMP. Have you seen the mib file?

Can't go wrong with APC. They all talk SNMP making it easy to monitor and alarm with EMS systems.

Very slight loss in cooling, unless at the very jagged edge you'll never see the differnce. But you'll get slightly better control.

Some dealers just didn't go WebCTRL till late. We STOPPED installing Supervision in 2001 with 1.5.

I've used SmartFan Nimbus on small 1 phase fans with good results.

Total central plant system at .5kw/ton is excellent, thanks for the feedback. Been trying to get my average below 1.00 kw/ton with some success. Got it down to around .8 at times. (5) chillers and...

Hell it wasn't. That old Atari was great little computer. It ran XPSI and hyperterm.

I agree. Many factors and many different systems can lower the number. But it would seem to be a very easy question.

I run into chiller plants that all seem to have .45-.5 KW/ton at the chillers. Great, but meaningless if the energy is wasted all around the system. The only way I know to measure how efficient a...

What is a good KW/Ton for an entire central plant. This would include towers, primary and sec CHW pumps and CW pumps. I generally see around .45-.5 KW ton at the chillers. When I add in all the KW...

I love when cutting over existing equipment on jobs, and then hearing "it works fine for years". When you can finally see all the bad valves binding damper and broken actuators on a pretty graphic,...

Holiday?? Job has to be finished by years end...24-7 equals..good I have 17 hrs left!!

Shameless plug. Sys is back..and so is his bravo sierra.

You'll need to pull some registers from the Yaskawa. CAS Modbus Scanner from Chipkin is free, simple and just works. Simply Modbus is better if your experienced with modbus.
I would bet it's a...

Based on what I've seen using Lon FTT-10, Arcnet/bacnet, and MS/TP bacnet. MS/TP gives the most options for iffy communication wiring. For example; I don't know how many times I needed to install a...

What control did you have an issue with? I can't think of one until your back to exec 4.
