Problem with Relay Mulitplexer Module Programming

[RS 485 Communication]

Sir,

I loaded a following vi from example code library.I am using Relay Switch Card(NI 2503) and DMM(NI 4060) for Measurement.

Switch_SCANNER_with_DMM_Handshaking.vi, This vi is same as shown in Relay Switch software manual.

In this vi, It demands niDMM configure Measurement.vi and niDMM Configure Meas Complete Dest.vi

These vis are not in old and new driver of this module, I used niDMM configure.vi and
niDMM Configure Meas Complete.vi instead of that vi by seeing same node.

Then after execution of program , Its showing error in niDMM Configure Multi point.vi
Error Code is : BFFA0010

Because in diagram there is shown TTL1 in sample trigger node and in given vi (niDMM Configure Multi point.vithere is
only one option shown Immediate.


so please solve these problems and how these vi which are not with driver, will be used or from where i can download these vi.

Regards,

Jitendra

Jitandra,

You can download a better version of DMM/Switch scanning example from ni.com in the Example code library. The name of the example is "DMM and Switch Scanning Examples".
These examples should be much easier to use than Switch_SCANNER_with_DMM_Handshaking.vi which should have been removed from our site.
Sorry for the inconvenience.

HI GF,

Thanks for reply, r u from NI company. I downloaded examples from code library.I want to discuss with u about thie relay switch card.

please tell me that in our hardware, i am using a custum built card(consisting multiplexer ICs) for making selection of more analog and discrete signal for measurement with the help of NI-2503 and NI-4046.

so finally i am using one channel of NI-2503 for 8 signals, and depending on selection lines, that particular signal goes to input of NI-2503 then through DMM I measure it. So in which manner, i should use DMM vi.

means only one signal will go to input of NI-2503 then connect input channel to COM 0 for measurement, measure that signal then disconnect. then repeat this sequence for no of tim
es.

I develop a program like it, But it measures only for first signal, Seperately through front panel of NI-Switch, It is measuring all signals, one by one.

Please give me solution to solve out this problem.

You please give your direct email- id

Thanks a lot
