The architect and customer preferred this wiring
scenerio because it is a datacenter if NCM or DX
goes down they want local control.

The first thing I thought was the AI to AO scenerio
but...

Have 2 fans and 2 DX-9100 controllers.
The fans go to a common duct.
They have separate discharge sensors.
If I installed a 4-20ma discharge sensor
in common duct, can I wire it to both DX-9100?...

Usually on the blue screen, you single click on the system
that the processes have been programmed for (AHU1, 1stfloor,etc)
It depends where they created the processes in Metasys.

The only thing I know of for DX power failures is below:

Is there a program for DX power failures?

Cause:

Solution:
See the Pwrfail.exe and Reset.exe files located in the DX-9100 Tools...

Have you tried to connect with hyperterminal?

Sounds like GPL is using an Analog Data point to write
the setpoint in CS object.
Go to processes in Metasys and see if there is a process called
setpoints or something like that.
If GPL files...

OK...but what about from the server.

I cannot look or modify the program from
the server if it wasn't in Visuallogic?

I have a school district with Envision for Bactalk on a server.
Each school has at least 1 TUX, ETH, etc.
The field controllers vary because they were installed
when they had IBEX.
I know I can...

Here you go....

Thanks again for your responses....
I will get pricing tomorrow on MP580
Can it be programmed through a Summit workstation?
I have Lonmaker but if I can use the workstation
it would be better.

No Lon,

Only Comm3, Comm4, and Comm5 on BCU.

MP581 might be too much.

This is the reason why I thought UPCM and now
you guys just reinforced my thoughts.

What Trane controller is best for turning boilers
on-off and controlling secondary valve?
Would it be UPCM?
We have Trane Summit BCU with workstation.

How do I find / modify the IP address for Summit?

Has anyone tried to bring the N31 into Tracer Summit
as BACNET/IP?
How hard is it?
Is there a point limit?

Your HVACPRO settings are fine.

You need to change your jumper on your actuator to
reverse-acting. But make sure when you lose
power to the actuator it spring returns open.

NAE and NCE are different controllers so THERE IS NOT a NAE25.

There is no NAE25, only 35,45, and 55.
Anyways, there is no simple way to reset passwords
without blowing the database away. (N.U.T. the NAE)
Then reloading it.
Are you sure you typed in the...

Yeah, but the problem is when maintenance turns the
univent off to change filters the command from the n30
goes away and defaults to summer until the master is toggled.

Have some univents with UNTs
that has sum-win binary input
I am using the N30 master sum-win
to override these inputs.
When univents lose power and come back
on, they default to summer because...

Does anyone have RTU, MAU, and VAV w/electric heat
graphics that they can share?
Either standard or advanced.

Has anyone tried to integrate into a Dectron
unit that has a Siemens OP393 III PLC controller?

Anyone know what the controller's protocol is?
