You asked for the best, it is by far the best I have used, plus not locking it down to a PC. The one you are probably looking at is the full package one, which is the best, you might be able to get...
Loytec LPA was the best one I used, also liked how I could use it thru their routers and not have to be physically connected.
Last time I did this...at least whatever refrigerant TP glide it was...I found a correlation where I could use a curve, then a curve and offset, then back to a curve and back again and it was pretty...
Can't say I am familiar with that particular controller, but it has the ability to program in logic for a exterior room that has a window.
So someone opens the window, window contact changes, in...
So briefing a document if the controller says 281 V3, then it is not networkable and standalone only. 281 NP is networkable. Same goes to all 280 and 300 series.
How would you know all refrigerant is good if no access to check?
High superheat typically caused by - low charge, excessive load, restriction in refrigeration flow, lack of subcool due to excessive...
What is the model of the 281?
Are there other series onsite (300/401) that pull in?
There is a version they sold in which it is not net-workable, built to be standalone only. From memory if the...
Look in the events and do a search on the point.
FWIW - should always have a manual reset somewhere, even if it goes back to the PLC. Had a job that was done really nicely, but someone's genius idea was a software reset. So every time it tripped...
Pretty sure you can make one from an I/STAT....just don't recall how right now, if nothing else, bump...and will try to look up later if I have time. I know I have an I/STAT at least....
Depends on the system.
Either way there will be a router/gateway to take it from Modbus/LON to Proprietary/BACnet, assuming the systems are physically connected. I guess there could be wireless so...
Lontalk communicates via their IP protocol (IP-852, Ethernet), given you have an IP gateway/router on the network and utilize such. Lon has 4 main mediums - FT-10 (twisted pair, typical in BMS),...
You are asking why an English only speaking person cannot verbally communicate to a Spanish only speaking person. Wonder if this is a setup "Lower controls line"....
Different Protocols...
Maybe I am missing something, but if a compressor vibrates, it's likely when it died or right after startup and then the startup guy removes the shipping bolts*/lockdown*....
In order of...
What kind of vibration issue is the compressor even having for this to be a need?
What type of compressor?
Compressors should just be pumping gas. If there's a vibration issue then likely,...
What are they using it for? You say supporting, but how - web interface w/graphics, Lon interface only/other? Was it ever configured?
Makes me wonder if they were just using it for a LON to IP...
CSI/TAC/Schneider yet has a main office out of Carrolton, TX.
If you have a 527 then it can do more than just be a NPR. If you have a 527-NPR then it will only operate as a NPR.
Replacement...
Rather have toilet paper blocking vent or feces?
Sounds promising, last I was aware was MP controllers only.
I wanted to daisy chain AS-P's and AS-B's, but couldn't on a project I was looking at....
Cool! Good luck with that project...from the little I've been aware it's been a bunch of band-aide's. Controls and limited access one only can do so much.
Agreed with previous statements, might help to widen out your setpoints between heat and cool as well. Worked on a CSI lab with similar issues...
So do you own a Velociraptor truck?
Raise the temperature in the room, people in the room are cold and if it's not that then lower the temperature in the room, as people are hot, bet first though. Other option may be to air...
It's a pretty nice controller, but depends on your background and what else you messed with.
Definitely among the best Schneider controllers I dealt with.
One thing I felt was lacking though was...
I don't know if I've ever taken more than 3 or 4 'business' days off in a row without responding to emails/phone calls in my working career.
Agreed on not wanting to make it too difficult on...
Interesting - 30 days PTO is nice, but on the other hand to be able to take time off as wanted without pay...Ok pay me more so I can bank it and then choose how much time I want off.
Been in...
Agreed! Thanks for response.
Not saying who is better as clearly to OP JCI is better. Hardware/Software vs. Service provider and/or training available are completley separate entitities.
FWIW this seems a bit harsh, but maybe I am biased. Believe me I had my issues with Struxureware, especially versions prior to 1.8 for what I was dealing with. I waited and tried 1.5 and refused to...
This has been done on a number of sites across the country. I dealt with one about a month ago, but Andover is not my strong side, so I'll let someone else chime in.
Ok if this a a pet project to learn from that is one thing, but you are taking a lot of risk and there is a lot of unknowns to your system. Economizer, VAV's, area climate, etc.
For a pet project...
Model of the board is written right on it, but pic to blurry to tell - it's an MR, but which type?
http://www.geusnet.com/~malonemg/TAC/TeckDisk/Inet%20Technical%20Documents.htm
sounds like parameter adjustments need to be done
I've paralleled power supplies numerous times and it worked fine, seen plenty from the factory as well on custom built OEM equipment. Yes ideally you have a big enough power supply and don't need...
Have you measured the amperage?
Have you measured incoming voltage to the transformer? Outgoing voltage from? Voltage at all devices on the transformer?
Have you done a load calc on the...
Look at heartbeat send times.
Don't know the controller, but many will not send updates unless heartbeat send time is set to something other than 0 or value changes over X delta.
Set it to a...
Fix install. Horizontal vs. Vertical requirement is typically done for heat dissipation. While I've seen hundreds probably installed incorrectly and working just fine...well most of those were in...
Sub'd as I don't know either, but I know I've seen them communicate to both BACnet and Modbus...
To me it seems you may have a port blocked on/to your computer or something....
For the AS to...
If you created a controller from a template it stands to reason there would be an xif, but can't say for sure.
What did you name it? Have you tried a search on the PC it was created on for that...

Good points brought up here.
Philzito - congrats and you bring up a very good point, many times older techs seem to feel threatened by younger techs and won't give out information and/or block out...
I did read and even re-used your words.
Your facts and world macro view must be much different than mine and others micro view. Agree to disagree, best wishes.
There's a difference between an idiot/stupid and ignorance.
There's also a difference between someone with a journeyman license and one without. Doesn't make one smarter than the other, but you...
Hmmm makes me wonder what mechanical background following engineers/controls guys screw up's I have dealt with in the past:
Person that controls an on/off compressor like a chilled water valve....
Aware of details on both (all old news) and would bet Struxnet was designed by likes of CIA/SIS once they knew what system IRAN had, or even where in on all upfront sales for product to make sure...
What wire type is it? The cable specs are critical
Does first loop have a router or repeater? If it does then it is not over.
If not easiest fix by far a Loytec LSwitch set up in 'auto learning mode' or whatever they call it - LS33CB and put it...
Just make sure you don't mix up polarity of those strings. :grin2:
Can do that on LON.
Can't find reference and not going to spend too much time looking. Not sure if it was a class or a...
Nope, had that conversation more than once and showed sign off. Issue resolved. Hell, I've seen factory units utilizing local PLC's for freeze stat protection and they stand by their warranty, so...
There's a bunch of issues here and not enough information. BetterDuck is correct, then to add to comments, mis-matched wire types and yet still working...
1. T-Taps are perfectly allowable on a...
"Better" all in the eyes of the beholder, like "Friends don't let friends Lon." Just saying...
A good coder/programmer in their 'familiar' language will almost always do a better job than using...
Second MaxBurn's comment. IME - Modbus/BACnet is pretty effective with integrating into ALC, and likely more so now that they have the Modbus IP driver for a PC and no longer need a LGR. My last...
