A Question about Reserved for Routing

[yiweihua2002]

My ATS has a NI PXI-2532 Matrix Card,and I Config it to 8*64 Matrix.In Max I set 8 rows(ro~r7) Reserved for Routing,and I use 6 columns(c0~c5) to connect two DC Power Supplys and One DMM,In Max I set the Channel Alias which connect to the DC PS and DMM to S1+,S1-,S2+,S2-,DMM+,DMM-,and other columns to a1~a37,Just look like the attachment.

In my test softwave,I often Use S1,S2,DMM at the same time.and the Signal Ground of these Device often connect to one column(for example a37).

My Question is when I set ro~r7 Reserved for Routing,and I use the [s1-->r7->a37] for the connect specification.and I can not use [s2-->r7->a37] or [DMM-->r7->a37],It will report error which mean r7 is Reserved for Routing,and It can not connect two terminals at the same time.I can only use "s1->r7 & r7->a37 & s2->r7 & DMM-->r7" connect specification,this syntax reduce my program readability.And I want ask if I have another Method to solve this problem.

Hi yiweihua2002,

I have a couple of suggestions:

1.  Write a wrapper around niSE Connect.vi to parse a readable syntax into the functional syntax.
2.  Create route groups to maintain program readability.  The route groups would contain the applicable independent routes.

The error you receive was intended to prevent customers from connecting multiple endpoints to the same "Reserved for Routing" path.  I agree that there is a use case to allow such connections, and NI Switch Executive users should be provided with this functionality in the future.  For right now, hopefully one of the suggestions above work for you.  Let me know if you have further questions!

Chad PSE,Thank you very much!

In deed,I do not like to use route groups,because if I want use route groups,I must config the switch executive in MAX.I have many test types,so it have many route groups in MAX.And if I use route groups I hardly know the switch connection route.For example,I set the route specification "5V",and I use it in labview VIs for switch connect specification.If I do not see the configuration in MAX,I can not know which switch is connect,which row is used to route.So I agree with your first method,Write a wrapper,this can improve readability.

Because the switch executive softwave have few users in china,and few chinese National Instrument AE support for this softwave,not like Labview.So I have the questions only to seek help in internet.Thank you for your help Chad PSE.
