dude
Did you get that lead tech job at the JCI branch yet?
I realize it is probably burried somewhere in a DX-9100 Point mapping table but
here goes.
1)_The DX-9100 is properly controlling two chillers using two P.I.D. modules
2)_The N-31 properly commands the occupied /unoccupied modes for all the remaining
UNT controllers .
3)_I want to have an occupied /unoccupied cooling setpoint mapped from the DX-9100 to the N-31 just like we have it with the UNT controllers and their H.V.A.C. equipment
If the space reaches the Unoccupied temperature I want the chillers to operate
Which points on the DX-9100 P.I.D. module do I map to the N-31 ?
Even if it means using a temperature bias or a second set of P.I.D. modules
What point contains the N-31 occupied/unoccupied command?
And how do I tie that command into the DX-9100 ?
Thank you

Dude, it totally depends on how the program is written. What's the program module # of the PID? PLC Logic? Local Setpoints? ACO's? Comparators?
More info needed.

I will post this for archival sake
I am using PID 1
I added the following points to the N-31
DCO2 - Digital Constant
PM1K6 - Change of setpoint at Off mode
PM1 l 5 - Logic connection for off mode
PM1OU 2 - Working Setpoint WSP
PM 1 K6 = "Unoccupied temp Bias" = 15 Degrees
DCO2 = "off Mode On /Off " I inverted the Connection
I added "off Mode On /Off" to the daily time schedule
The Local setpoint PM1K1 is 70 degrees
When the schedule commands DCO2 Off , it Inverts to On and is connected
to PM1 l 5
The working setpoint rises 15 Degrees to 85 Degrees
The only minor problem is that the operator can not directly enter
an UnOccupied Setpoint They have to use the Temp Bias
But it works
Thank you for the good Johnson Link
If the pay was better I would accept the Tech job at JCI
How much do they pay?
Not enough.They seem like they were having problems recruiting peole
You could also write an ACO to the program and add a or statement to any PLC that makes the DCO (occupied) to a "set" and only let the next unoccupied "reset" the DCO.
Having the program in the DX will allow the controller to operate stand alone.
To me Stand alone is better for most applications.
(Duh)
That is a good idea
But ,I would still have to use an interlocking object in The N-31
to open and close the DCO
1) The space temperature sensors are connected to a UNT controller on the third floor those points are globally shared by other UNTS
2) They want to control the Unoccupied Occupied feature thru the OWS
_ connected to the N-31,they do not want any standalone controllers
I am not quite sure how to address points using the hex address and writing
or reading to an individual byte in a function module
(
Example
the eight channel comparator module uses the three last bits of a byte
(X1 ,X2 ,X3 ) to disable the channel and or to set the comparator type
In the old days I would use to use peek and poke commands to set the individual
bits of a byte
Not to beat a dead horse, but if the ACOs are available use them with a selector toggled by a DCO as OCC, UNOCC, write to it from the OCC-S of the UNT. Of course theres a million ways to skin a cat.
As far as JCI if you talk to the right person, theyll promise you anything you want to hear
On the service side Id suspect the axe will soon swing. The Jork merger has just slowed them down a bit.
You have no clue what you are talking about. Service is stonger than ever
now that all the dead weight is gone. The below statement is 100%
accurate. You incomptant hacks piss me off.

That’s right out of your sales 101 cook book. Read on brother you’re the only one on this site that’s dumb enough to believe any that horse****.
It reminds me of the commercial when the guy is going buy a Sealy mattress and dreams that his boss gave him a raise, a condo in Barbados and gave him his big executive office, THEN HE WOKE UP!!!!!! When the salesmen interrupted his dream. Funny thing is his name was Johnson.
Dream on buddy, In Connecticut JCI has the most dissatisfied customers of ANY control company, branch office of the big 3 or local independent. You should attend a BOMA, IFMA or ASHRAE meeting and maybe you will be enlightened on just how HORRIBLE your customer service is.
How is it that you have the best service techs when in this area the average life expectancy is 2 years or less before they leave.
I take it you sleep on Sealy too!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Very interesting , every way to skin a cat is good to know
I am using a DX-0100
How would I write to it from the OCC-S of the UNT ?
Please let me know
JCI is on no verge of going down
It goes by the branch, down in our Jersey / PA area The York guys are very busy
I see the poor guys in the supply house and they are busy
Do you have any idea how many hospitals , schools and buidings use York
centrifugals and equipment.
In this part of the country they are very common place
Good move on JCI
the only other company that comes close is Trane,
and JCI attempted to
purchase them also
clean condensor you remind me of the wise custodian from another teen movie! It is not as cut and dry most of the time. At this point of time you'd better be dead if you are not busy. There is no quistion JCI can sell and in order to do it they will try screw up anyone they can. First target employees. As a union member you should really be aware of that. In the end it is quistion of profit margin which will break or make JCI/York. And unfortinatelly if JCI will survive the first thing they will do - try to get rid of higher paid workers and replace or outsource them with lower paid. So do net get excited- better JCI is doing - will be worse for you personally.
Blue,
Im glad you feel that way, however, please refer back to the brochure you were handed at the last Pow-Wow, (Id quote but I torched mine) I think there was mention of being the best in class without being Arrogant. Some work may be required here.
Fact, if a reasonably intelligent person actual did pay attention there was mention that the next company focus would be on increasing the productivity and profitability of the service side. I know from the other side of the house, productivity gains equaled a lot of OT (Own Time for the short bus riders out there).
Professionalism is another good point raised I doubt if attacking the credibility of a person (you dont even know) would fall under that category. Some work may be required here as well.
Since the Vision statement was raised, personally I think the new logo is inverted; Green to Blue would be a more accurate depiction of the current strategy; experience is now trumped by cheap inexperienced grass green skill sets. You embody the future of JCI my friend.
And on that note, its a shame that a companies Values would view individuals who gave the company so much, that posses the knowledge, and seasoned experience to get it done right the first time as dead weight; (translation for the virgins out there) working your way up the ranks to actually earn a decent wage equals dead weight. Now thats a strong future.
On a positive note, it warms the heart to know that there is a steady stream of naοve people out there enthusiastically selling themselves short, believing in catchy job titles, elusive incentive programs and nifty slogans. I hope the view of the underside of the bus youll likely be thrown under is greeted with the same bravado sport. But than again sycophants are generally spared on the first swing of the axe. Please keep doing what youre doing for less than the street wage. My JCI stock is doing well thanks to such efforts, absolutely no sour grapes here.
Back to the actual question, that was a DX-9100 and an N30?
I would not worry about Indy. He’s like the occasional hemorrhoid flair up. Just when you think there gone all of sudden they appear.
Like a hemorrhoid he to will vanish for awhile then in a few days he will reply to a thread and call someone a hack.
He will read my replies and yours and will not say a word because he knows he is a complete idiot who knows nothing about controls and continues to be a useless tired TROLL….
The only reason JCI even keeps him around is he is competent and efficient at refilling the paper towel and soap dispensers in the Indy branch office. A good day porter is hard to find these days.
Yes it is a DX-9100
and an N-31
The moderator should make a new category for Johnson and Trane gripes
It is just a job and it is just another company along with
hundreds of others
Who really cares about this stuff
The goal is to make money....
The information here is used to
complete the job ,keep the customer happy and keep the money coming in.
Anyone who is in the service industry and who thinks any different will always have a hard time with ANY company
The majority of people who post here are looking for technical answers
and not disgruntled employees.
I f you can not answer the question or if you feel it is "below" your many skills then why can you not post your gripes on another thread
Yes it is a DX-9100
and an N-31
Thank you
If its arrogant and degrading? Why is it policy?

Honestly, never work on an N-31,
On an N-30 youd add an interlock object by browsing to and highlighting the programming container, press the F3 add key, select interlock and press enter. Add a source to the interlock object, next add action table entries. Typing in the object you wish to command F3 to save
.
An NAE is similar with intelock logic but LCT can also be used for more complex stuff like high/low select of the zones in that case you could just write to 1 aco the desided setpoint to the PID with the mux in LCT. The main point I was making is that inside the DX the ACOs and a selector toggled by a DCO would give you everything youre looking for. Ive done many DXs, loads of GPL and a fair amount NCs, NAEs and a few N-30s. Sorry no N-31
