Mercury Relay Contact Resistance using SCXI 1127

I am trying to measure Resistance on PWBA with Mercury Relays using SCXI 1127, 1331 connector block and DMM 4060. I am using 2 wire mode. The Mercury Relays have 0.25 Ohm contact resistance. The readings measurements fluctuates and are high measuring from 0.7 to 1.5 ohms. I would like to know what is the contact resistance of SCXI 1127 Relays and any suggestion to improve measurements. Why the measurements fluctuates every time. Do you think any common grounding considerations or programming changes can be done to improve. Any suggetions ? Thanks.

SCXI 1127 4-wire software setup

Hi All
I experienced a problem to connect channel ab0 and ab2 to the respective measurement channel so that I can get a resistance reading. I'm using SCXI-1127 with 1331 and a DMM of HP34401A.
I have done my wiring correctly and now it's a matter of coding it correctly. There are lots of way to do this in my mind. Tried each one of them and didn't work.
Any help (software or detail of coding sequence) will be very much appreciated.
David Ng

- Use the chassis created in DAQmx.
- In MAX (SCXI-1127 property) select the SCXI-1331 as the terminal block for the SCXI-1127.
- Use the shiping NI-SWITCH example found in: F:\Program Files\National Instruments\LabVIEW 7.1\examples\instr\niSwitch called niSwitch Making Connection on a Switch.vi.
- Delete the second connect vi and wait for debounce
- Point to your SCXI-1127 (SC1Mod4 for example)
- Change the topology to "1127/4-Wire 16x1 Mux"
- Check the NI-SWITCH help file (Start>>Programs>>National Instruments>>NI-SWITCH>>Documentation>>NI Switches help) for valid channel names under: NI Switch Help>>Devices>>SCXI-1127/1128>>4-wire 16x1 Topology

SCXI--1127 relay banks layout

When using the SCXI-1127 in the 2 wire mode configuration, will it be using only the 32 relays located in the left bank of the PCB?
I am trying to measure the path resistance in this configuration, but I need to identify the relays used in this configuration. The PCB has a total of 45 relays distributed in two banks, can you confirm with me that only the 32 on the left bank are being used in the 2 wire mode configuration?

Hi maggan,
To answer this specific question and related inquiries, I strongly recommend the NI Switches Help (installed with the NI-SWITCH driver). Download the Help by itself using the following link:
NI Switches Help
http://digital.ni.com/manuals.nsf/websearch/B133DDD29F0DFCC28625746E00564E56
The relay replacement section is a great resource for information such as which relays are used to connect a particular channel to COM. In the attached picture, I've outlined the relays used to connect ch0 to com0 in the SCXI-1127's inherent 2-Wire 32x1 Multiplexer Topology.
Let me know if you have further questions!

Low level control of SCXI 1127 relays

Hi,
How can I close or open switches HLSELECT and 1WIRE of SCXI-1127 manually? There is a VI(1WireINDEP) which uses CIN to activate these switches. This VI allows to activate HLSELECT and 1WIRE relays when the SCXI 1127/1128 is used in 1 wire mode as a 64x1 multiplexer. The 1WIRE relay will always connect to 1wirelowref signal. The HLSELECT will connect to Com0+ when H-L Channels is set to Channels 0-31 and to Com0- when H-L Channels is set to Channels 32-63.
I need to control 1WIRE relay just like this VI controls HLSELECT relay. I have attached this VI. Can you please modfiy it or write a different VI to allow controlling 1WIRE relay. I should be able to open and close these two relays (HLSELECT and 1WIRE) manually thro
ugh the VI. If this is not possible, can we modify this VI so that the 1WIRE relay will always connect to com0- signal instead of 1wirelowref signal.
Thanks

Thanks for your reply. My problem is not that simple.I am using NI-SWITCH1.6 and need to continue using it. Can't I just use this VI as sub VI and call it? Here is my problem:
I am building a system to test cables that are open at both ends. A cable can have 4, 6, 8, 10, or 20 wires in it. I wish to test the resistance of each individual wire in a cable and insulation between wires. I have four SCXI 1127 modules with SCXI -1331 in a SCXI 1000 chassis. The switches are controlled by a PCI-4060 DMM.
I have written a VI ( in Labview 6.1, NI-SWITCH 1.6, NI DMM 1.6), which configures DMM for multipoint measurement and SCXI 1127 modules in scanner mode. I connect 1_WIRE_LOW_REF of all SCXI-1331s to a common point, which connects all wires in a cab
le/s under test. So, by using SCXI in scanner mode and generating scanlist, I can measure the resistance of individual wires. I use 1127 in 64 x1 multiplexer mode. This takes care of one requirement.
Now for insulation testing, I keep all wires of cables connected to switch channels and need to connect them in combinations. I can generate the combinations and pass it in a loop to close or open switches. I need help in creating correct paths and route the measurements to DMM.
For example:
Let�s say, we have a four wire cable, I need to test the insulation between them in pairs. There are six possible combinations: 1-2, 1-3, 1-4, 2-3, 2-4, 3-4. Let�s say these wire are connected to ch0, ch32, ch1, ch33 of module 4, the VI may need to close the switches as per the paths required (attached in word document).
I just don't know how can it be done.

Trying to use SCXI-1128 independent mode for 64x1. Demo doesn't correct issues

I'm trying to use the SCXI-1128 with the independent topology as both a 32x2 and a 64x1 switcher. I have no problems using it as a 32x2, but when I try to control the HLSELECT and 1WIRE relays, I get errors. I can see them as "open", but if I try to "close" either of them I get an error or a no path exists message. I've tried to use the demo from a previous post:
"How Do I Program the SCXI-1127/1128 in Independent Mode as a 64x1 Multiplexer?"
but it still doesn't allow me to utilize the 64x1 configuration. Am I missing something here? Why won't LabView allow me to connect HLSELECT and 1WIRE and how can I get around this problem? Has anyone had success with using the 1128 as a 64x1 m
ux. Just to fill in the rest of the hardware blanks, my communicating device is a 4060DMM and can only be used as a traditional device. I also have a SCXI-1331 attached to the front end of the 1128. Physically, I have a 1k resister from ch0+ to 1_wire_lo_ref and that's what I'm trying to measure with the DMM. As I said before, I have successfully measured voltage and resistance in 32x2 wire mode. Any help would be appreciated!
Thanks,
Andy

Do you know of a good way to cancel the path resistance?
It sounds like you may have solved my problem here. I'll have to try this out and see. Basically what you're saying is I have to configure all the channels (using MAX) to 1wire. Then I can freely use the independent mode to make 1,2, or 4 wire measurements with full relay control??
If that's the case then you may ignore the following. If that isn't the case, let me describe what I'm trying to do.
I'm glad you pointed out that last piece of information. The reason I want to use this device in independent mode is because I plan to account for the 400 to 800 ohm path resistance of the 1128 (and not have to buy a 4070). I think I can do it, but I'd have to be able to use any channel (ch0 for example) as both a 1 wire and a 2 wire terminal (no need to do it simulataneously, I just have to be able to go back and forth). If I phyically connect ch0+ directly to 1wire_lo_ref and connect ch0- to my 1K resistor and then connect the other side of the 1k to 1wire_lo_ref, I am hoping to be able to determine the path resistance of the entire switch. In order to do this I'd have to take three 2-wire measurements. One from ch0+ to the ref, one from ch0- to the ref, and then I'd have to set up ch0 as a 2 wire terminal and measure the entire path resistance. By using the first two measurments I can calculate the parallel resistance of the ch0+ and ch0- and then I can do some math to cancel out the path resistance. Long story to come to my ultimate question, but I guess what I'm asking is:
Can I use the 1128 in independent mode and configure ch0 as a 1 wire channel (i.e. ch0+ and ch0- with 1wire_lo_ref as a common) and then configure it as a 2wire channel(simply ch0)?
Here's an ascii of the circuit:
|=== 1wire_lo_ref
|
Rpath(1wire)
_____|___________
| |
1K |
| |
Rpath ch0- Rpath ch0+
| |
ch0- ch0+

Thanks for the help, I hope configuring all channels to 1wire will solve my problem.

Trying to measure voltage through SCXI-1127/1331 1-wire connection

We have NI hardwares like: 1) Chasis SCXI-1000, 2) DMM PCI- 4060, 3) MUX SCXI-1127 and 4) Terminal Block SCXI-1331
We have a system with two large glass plates standing vertically and placed parallel to each other each having 24 electrodes on them. Distance between them is 4-5 inches. The plates are places in such a way that the electrodes are on the outer side and accessible to the user. We are trying to flow different liquids of different density through the channel in between. Please find attached a picture of it.
So a total of 48 electrodes and hence, wires are connected, 24 on both sides. On each side there are 3 rows with 8 electrodes/row, making a total of 24 wires. Wire#1-24 are on side A (say) and wire# 25-48 are on side B (the other side). The medium between the two sides will be salted water (say for now).
We want to measure potential/voltage in such a manner so that we can calculate the voltage difference between all possible electrode combinations between side A and side B. Like V1-25, V1-26, V1-27,...,V1-48,V2-25,V2-26,........,V24-48, all 24 X 24 possible combinations. We are connecting two end of a power source to side A and side B so that there is some current flowing in the water.
I have connected wire# 1-48 to 1-48 in SCXI 1331 (left out the zero to avoid confusion). Now that I'm measuring values through the program attached ("Scanning_....vi"), I can see that the first 16 values are showing some values of standards E-2. But from 17-48 are showing values of standard 5E-3 and I guess they are not taking any values at all. Can you tell me why this might be happenning?
Can 1-wire measurement be applied for this scenario. If not then let me know how to achieve our goal. I can manually take a Multimeter and measure all the combinations one by one, but measuring all the values at the same instance would be better and that only can be done by automation and I hope that the NI hardwares I have, should be sufficient to do that. Please let me know if it is otherwise.
Another thing, in one of my previous contact with NI someone mentioned connecting 1_WIRE_LO_REF. Is it needed in this case? If yes, then if I connect one end to 1_WIRE_LO_REF, where should I put the other end?
In case the program is wrong or more than 16 values can not be taken please let me know alternate path or show me how to make changes in the program. I would appreciate your help in this issue. Thank you.

I connected the COM of my power source to the 1_WIRE_LO_REF. There are 4-5 points to connect. I choose the middle slot. Is there any significance of assigning so many slots to 1_WIRE_LO_REF?
No change in result. Can you please test run the program I attached and see whether it's correct or not. You'll see 48 segments getting the output. First 16 of them are showing some seemingly proper values. rset are either too small or as big as 5 V.
I'm providing 5Vs from the power source. You might have seen the old analog ones. I'm using one of them. there are different Voltgae option. I'm using the 5V and so I've connected a wire from the 5V connection to one of the electrodes on B side (28th electrode) and the COM ports goes to the A side (4th electrode) and also to 1_WIRE_LO_REF.
Now I'm thinking if the program if not working. Because it seems that we are getting (seemingly) proper values for the first sixteen and something's messing up the values for the the rest of the electrodes.
Do I have to use two 24X1 MUXs i.e, use physically different boards and also two different programs to measure them? Or I can just use 1-24 as 24X1 and 25-48 as another 24X1 in the same board and measure them through the same program? Thanks in advance.

SCXI-1127 problems

We are using a SCXI-1127 module, a NI-1331 terminal block, and a NI-1000 chassis. I set up the chassis and module correctly and wired up for 4 wire resistance measurements. I Connected the signal to channel 0A and 0B for 4 wire measurements. When i go to test, i can't get any measurements. Under the properties for the 1127 we have it set up for 4 wire mode on channels 0-15. We tried to make a virtual channel then run the tests on that channel and can't get any resistance measurements. Any ideas what could be going on here?

Hello Leonard,
First of all I would like to make sure you are connecting your signals correctly.
In the NI Switches Help (April 2003), go to the chapter "NI Switches Help >> Device Overview >> NI SCXI-1127/1128 >> 4-Wire 16x1 Multiplexer Topology". It shows there how to connect your signals and it says "In 4-wire mode, connect your excitation or source leads to xA+ and xA- and your measurement or sensing leads to xB+ and xB-".
Question 1: Are you connecting the excitation signal to 0A+ and 0A-, and the resistance legs to 0B+ and0B-?
Question 2: Use the example program "niSwitch Making Connections on a Switch.vi" in LabVIEW that s
hips with the NI-SWITCH 2.0 (or later) driver to choose the appropriate topology and to connect CH0 to COM0. If you measure in your terminal block the pins that correspond to OUT0 and OUT2, can you see the appropriate signals?
Question 3: What device are you using to measure signals from the switch? The NI 4070 DMM? Another NI DMM? If so, connect AB0 to OUTo and AB2 to OUT2 and try to get the readings in the DMM from the backplane of the chassis (see Switches Help for more information).
Question 4: How are you creating a Virtual Channel?
Talk to you later,

SCXI-1127 Module behaviour

Hi,
I'm using 4 SCXI-1127 modules in 1 wire mode. Lately, I've been experiencing problems with one of the 4 modules. When i try to read resistance of 4 individual resistors by connecting them to any of the 4 channels of modules installed in slots 1,2,and 4 of SCXI 1000 chassis, it gives me correct results. But with module in slot 3 i get two 'NaN' values either on 0 & 1 channels or 32 & 33 channels. I did troubleshooting via MAX and NI-Switch soft panel, but couldn't figure out what's wrong with it. If anybody has any suggestions please let me know. Meanwhile i'll try exchanging module in slot 3 by modules in other slots.
Thank You

Hi,
I�m experiencing a similar problem. Module in slot 1 is giving me
�NaN� values. I tried swapping modules, added and deleted them through
MAX, and rebooted the PC several times. All the modules are working
correctly, when inserted in slots 2, 3, and 4 of SCXI 1000. I don�t
understand what�s causing the module in slot 1 not to work. I tried
debugging it through soft panel too, but the problem still persists
!. Any suggestions??
Thank You

Trying to measure voltage through SCXI-1127/1331 2-wire connection [ Edited ]

Hai ,
     this is madhava from LSU,I am working on ERT with NI hardwares like 1)chasis 1000 2) DMM PCI-4060 3) SCXI -1331(2 in number)
I have a system with two large glass plates standing vertically and placed parallel to the user.I am trying to flow different liquids of density through the channel in between.Please see a attached picture of it.
    There are total of 48 electrodes 24 on each side to which wires are connected. On each side there are 3 rows with 8 electrodes/row, say 1-24 on side A and 24-48 on side B. The medium between the two sides is salt water.
     I want to measure the potential in such a manner that I can calculate the voltage difference between all possible electrode combinations between side A and side B.I have connected a two end power source to side A and side B, i.e. +ve to side A and -Ve to side B , so   the electrode on the A side acts as the "source" and the electrode on the B side acts as "sink".
    I want to use 2 SCXI- 1331 's for this experiment.
    I tried it with 1 SCXI - 1331, but did not get proper values.So what do you suggest shall I continue this with the 1 wire or could you please help me with the two wire experiment, so that I can get more combinations.
           I hope you respond soon and in the affirmative.
With regards
Madhava

Welcome to the discussion forums, Madhava!
The optimal solution is to have a 2x48 (or more) matrix so
that you could easily choose one point on either plate (column) connected to
one lead of the DMM (row0) and another point on the other DMM lead (row1).
Since the SCXI-1127 doesn’t support this configuration, you’ll have to try
something else with your existing hardware.
Because you can only use a multiplexer setup instead of a
matrix for your number of signals, the closest you can get to the above
suggestion is to measure one electrode to ground and then read the next
electrode to ground and include logic to find the difference between the two voltages.
I suggest you start with a LabVIEW shipping example (Help » Find Examples) such as niSwitch
DMM Switch Synchronous Scanning.vi or niSwitch
DMM Switch Handshaking.vi (found under Hardware
Input and Output » Modular Instruments » NI-SWITCH). You will have to modify
it to include another SCXI-1127 and set them both up in a 1-wire 64x1 multiplexer
topology. Take measurements as quickly to each other as possible on both
switches. Again, this is a workaround to what you really should be doing for
optimal performance (and the easiest setup).
The last option is to limit your measurements to electrodes
directly across from each other (or any other fixed mapping setup) and use a
2-wire 32x1 multiplexer topology. By nature, this is taking a differential
signal measurement between two constant points. This would allow you to easily
use LabVIEW’s shipping examples without modification.
I hope this helps you get a feel for your options and the
consequences of each.

Multiple scxi 1127 switches scanning, dmm 4070

Hi,
I am using 2 switches SCXI-1127 in a PXI/SCXI combination chassis. The readings are done through a dmm 4070.
I need to scan 60 thermocouple channels, i.e. 32 on the first one and 28 on the second switch. Now, I found http://zone.ni.com/devzone/cda/tut/p/id/3658 stating that a scanning multiple SCXI switches is using legacy DAQ functions in niSwitch for these specific siwtch cards (1127).
What version of niSwitch was it? Is it still true now? Why is that? Or should I use the new way using DAQmx?
thank you
alex

Hi Alex,
This is still the case with NI-Switch 3.3.1. Due to hardware limitations, scanning multiple SCXI-1127 modules is not a simple task with the NI-Switch driver. I would recommend using the DAQmx example "DAQmx Multi Switch Synch.vi" if you are performing synchronous scanning. I have taken a screen shot of the front panel of a working VI to help get you started.
In general, it is more efficient to use DAQmx when scanning multiple switches. When using NI-Switch to scan multiple switches, it is necessary to maintain a session for each switch module. When using DAQmx Switch, you need only open one task. Using DAQmx Switch increases programming efficiency, keeping your code neat and maintainable.
If you need further explanation or if you have further questions, please let me know!

SCXI-1127 and Reset NISwitch VI

I have a question with regard to resetting the SCXI-1127 Card.
I wrote a test VI that performs the following in sequence to
verify the -1127 operation:
1) Initialize the SCXI-1127 Card
(using a Instrument Descriptor of SCXI1::5::INDEP)
2) Control a single Switch (Close ch0)
3) Close the NI Switch Reference
The switch closes correctly, because I can hear it, but here is
the kicker, if I put the entire 3 steps in a While loop controlled
by a Boolean stop switch and run the VI, the Switch chatters (its
being opened and closed continuously). Now I realize that this is
normal operation *IF* the Initialize NISwitch VI is performing a reset
of all of the switches (i.e. OPENING all switches). However, I am
setting the ResetDevi
ce Input Boolean to False when I call the
Initialize NI switch VI, but it appears that the board is resetting
anyway. Has anyone seem this before? or is the Reset Device input
on the Initialize NISwitch VI not what it appears to be to me?
(The reason I am attempting this is to assertain that I *can* call
initialize (to get a reference) without changing the current state of
the switches. this is because I am leaving the LabVIEW environment
between switch setup calls, therefore I need to close the open
Instrument reference)
Any Help would be appreciated

Before you buy.

Rick,
you are right: the reset option in this moment is not yet performing any
action inside the NI Switch driver. We apologize for the inconvenience: it
will be activated in future release of the products. Unfortunately, in this
moment it is not possible to avoid the RESET of the switch card when you
open a new session.

2.5MHz oscillations on scxi-1127 AI channels

I'm trying to measure the circuit below through a SCXI-1127 multiplexer and I'm seeing a 2.5MHZ sinusoid when I connect my circuit output to the multiplexer. Alone, I don't see this signal, but as soon as I connect to the mux input, it pops up and it is very large. I can see this signal not only in my software but with an O'scope probe across the circuit's output. The circuit is a simple Inverting amp and I'm using LT1212 op amp. I'm also using a virtual ground between the rails since I'm running on battery. When connected to other DAQ's or Oscilloscope, I get a clean signal, but when connected to SCXI-1127, it shows up - even when the switch isn't on. Any suggestions or ideas of what the cause might be?

Classical event: Amplifier oscillate, while oscillators won't
How much bandwidht do you need?
A small cap (5-100p) in the feedback loop and a 10R right after the OP output help
The reason for the oscillation is the higher capacitive load.

SCXI-1127

I want to connect 15 different sensors to one channel of the data acquisition device (USB-6259) through the multiplexer (SCXI-1127) because I need maximum sampling rate of USB-6259.
I tried to run one NI-Switch vi example in SignalExpres. However, it does not run it by asking the file location of the control named "niSwitch Topologies.ctl". In my computer, there is no such file.
If anybody knows how to run NI-Switch vis in SignalExpress, please let me know.
Thanks in advance.

Hi naba,
Thanks for posting on the forums! I just wanted to address one thing before answering your question. The max switching rate of the SCXI 1127 is 100 channels per second. If your application requires you to switch through each sensor at a faster rate, you’ll have to consider other solutions (PXI, or SCXI with solid state relays). There are tradeoffs however (such as higher input impedances), so you will have to weigh those factors with your application needs.
The examples provided with NI Switch were meant to be run in LabVIEW. Refer to this devzone article on how to call a LabVIEW VI from Signal Express. Also, this knowledge base article gives detailed instructions on how to prepare a VI to be called from Signal Express.

Can two users on the same Mac sync contacts by using the same Apple ID in the iCloud settings?

Can two users on the same Mac sync contacts by using the same Apple ID in the iCloud settings?

Hi Barney,
That's exactly what I want. I have a personal user and a business user on my MacBook Pro. I want both users to have the same contacts so if I add a contact while I'm logged into my personal user, it will show up when I'm logged into my business user. I want both contacts books to be exactly the same; like you said. So, I used my business user AppleID when I enabled iCloud for my personal user and I enabled iCloud for my business user with that Apple ID as well. For my personal user, I selected Contacts and Calendars to sync with iCloud. For my business user, I selected everything to sync with iCloud. The problem is... it didn't change anything. I restarted my computer to see if that would do anything but nothing happened. I'm not super savvy with Apple products, so maybe I'm completely confused.
Hi Xeni,
Thank you for your response, as well.
