Add an IVI Step Type
I would like to use an iviRFSigGen with teststand (Currently using ver 2.0). Can I add a step type to do this or is there a step type already available to do this.
Hi,
We have a beta version of the custom step "IviRfSigGen".
Unfortunately, it was not tested so well, it seems like starting exsample for you.
Please see the attached zip. file and Your comments and suggestions are very welcomed.

The type library information for 'TestStand IVI Step Types' was not found (Error code: -18351)
Hi,
I get the error in the message subject when I add an IVI-C step (no matter IVI Power Supply, IVI Dmm or others) and try to edit the step by pressing Ctrl+E (or double-click the step and click "Edit IVI Power Supply" for instance).
I have installed 2 IVI-C libraries that I downloaded from 'NI idnet' both with IVI technology (namely agn330xa_MS.msi and agn6700_MS.msi). They can both be seen in Add/Remove programs under "NI IVI Specific Drivers" group.
The error message says "Make sure the server is registered".
Does anybody know what server is it complaining about and how can the registration be done?

error 18351.jpg 66 KBHi ebalci,
I believe this error is occurring because the ActiveX components that are used by the IVI step types are either not properly installed or not properly registered. I would recommend first making sure that the IVI compliance package and NI-VISA are installed on the system. If both of these are already installed, I would recommend running the TestStand Version Selector because this should re-register the ActiveX components used by the IVI step type. The TestStand Version Selector can be found by going to the Start Menu>>Programs>>National Instruments>>TestStand 3.5. You will need to select the version of TestStand you want to use and click the "Make Active" button. I have also pasted links below to VISA and the IVI compliance package. Hope this helps!

When i run the sequence with ivi step types in simulation mode i get the error Types do not mathc. The step that generates this error is an IviScope step type and is configured as a measurement. Th weird thing is that in real mode is working perfectly. I have three measure steps and i get the error in all of them. The exact error message is:
UUT Result: Error, Error executing substep 'Post'. An exception occurred calling 'RunStep' in 'ISubstep' of 'TestStand Ivi Step Types 1.0 Type Library' An error occurred while executing the step. Component Works IVI Control Error: The IVI Read operation failed on channel '1' for logical name 'SampleScope'. Details: (1
) Types do not match. [IVI Error Code: BFFA0015] Source: TSIviStepTypes [Error Code: -30721, User-defined error code.]
Can someone tell me how to fix this problem?. It seems to me that the simulation generates a diferent type of measurement of that generated in real mode.Update:
The simulation driver appears to be raising the error. By switching to specific driver simulation the error does not occur. This may be a problem in either the class simulation driver or the specific driver.

Does IVI Step Type support NI PXIe-4112?
Hello, Guys
I have a PXIe-4112 and four of PXI-4130. When I try to configure my PXIe-4112 with the PowerSupply IVI Step Type, an error occurred.
An error occurred calling 'RunStep' in 'ISubstep' of 'zNI TestStand Ivi Step Types'
An error occurred while executing the step.
Component Works IVI Control Error: The IVI Configure operation failed for logical name '4112'.
Details: Attribute or property not supported. Attribute: NIDCPOWER_ATTR_OVP_ENABLED, Channel: 0 [IVI Error Code: BFFA0012]
Source: TSIviStepTypes
Surely I disabled the 'OVP Enabled' check box at the Edit IVI Power Supply Step Dialog. My system configuration is,
IVI Compliance Package 4.6
NI-DCPower 1.8.6
NI TestStand 2012 SP1
My PXI-4130s are working well with the IVI Step type. Does IVI Step Type support NI PXIe-4112? Or am I doing something wrong about it?

4112.png 17 KBHi Joonam,
The PowerSupply IVI step will not currently work with the 4112.
The 4112 does not support OVP. If the NIDCPOWER_ATTR_OVP_ENABLED attribute is set to True, the error that you described is expected. If it is set to False, no error should be generated. However, an error is generated when it is set to false. This is incorrect behavior in the driver and has already been documented under Corrective Action Report (CAR) #437105. This issue will likely be rectified in a future version of NI-DCPower.
The PowerSupply IVI step is hard-coded to set the attribute to true or false, based on the value of the check box in the Limit tab. The workaround to this problem is to replace your PowerSupply IVI step with a step based on a code module that doesn't try to set the OVP_ENABLED attribute at all.
I apologize for any trouble that this has caused you. Let me know if you would like any further clarification.

Latest IVI Class Step Types in TestStand
IVI instrument classes have recently been defined for RF Signal Generator, Spectrum Analyzer and Power Meter. There are IVI drivers for these classes available for download from the Instrument Driver network. However, TestStand3 does no contain step types for accessing these drivers. Does anyone know when NI plans to add support for these to TestStand? Has anyone created step types for these classes, or have an example of how to do this?

There is no documentation on the low-level workings of the TestStand IVI step types. As with many of the step types that have source code, it is available as examples of developing a step type in various languages.
The additional work to add the a new class to the TestStand IVI step types is not small, that is why to date we have not done it. The amount of work could be divided into the following areas:
* Update the TsIviStepTypes to add the new class to the enumeration.
* Create the new step type definition (subproperty structure) based on the IVI spec.
* Upcate the TSIviStep and TSIviSFP code to allow you to edit and perform the work to process the expressions and initiate the various IVI class operations.
* Add low level
IVI class layer logic to talk to the IVI class driver. This piece was previously done in a VB ActiveX control written by the Measurement Studio group in NI.
The last two items are the biggest and they would take some time. That is why I was suggesting creating specific Action steps that call into custom code modules to talk to IVI directly, that is, no edit dialog box, no SFP, etc.

Hi everybody,
I'm looking for tips, pointers,directions... to be able to perform this operation in TS 4.0 sequence Editor, if it's even possible...
I'm managing a test system with a "home-made" virtual instruments abstraction Layer complementary to IVI classes for instruments which do not have classes defined, customizing the sequence editor accordingly for developpers of my department.
So basically when the instrument is IVI, the developper uses the built-in IVI step-type type and when it is not, he uses the the custom step types that I developped for this particular class of instruments.
However there are classes where I do have both IVI and specific drivers available and I do need to use both in the test sequence.
For example let's say there are two sources of DC power available in the testbench, one being a programmable IVI compliant DC power supply, and the other one composed of fixed "blocks" of DC power supply managed by externals relays and you need to use them both in the test sequence.
What I would like to be able to do in the sequence editor is inserting the appropriate step type at edit time just by selecting the source of power supply (by a ring or enum for eg), and if the first ressource is selected, it inserts IVI step type, and if the second ressource is chosen, it inserts the appropriate custom step type.
Any Ideas on how to accomplish this ?

Cyril

Go to Solution.Hello Cyril,
Here is an idea that could be done:
You could create a dynamic step by having a step that holds all the properties for both configurations (the superset of the necessary variables) and an extra one that indicates which 'mode' the step is in. Then you create the main Edit substep in whichever language you desire. That substep window will then have a box/dropdown/etc. at the top you can use to choose between modes A & B. When the user changes the value, you would dynamically change the rest of the window to contain the appropriate properties for mode A or B. You then copy the property values in that window to the Step properties, and copy the mode to your variable and you can run the step in that mode. When the step then runs, it checks the mode variable, and depending on its value, it will run the step in mode A or B.
Now we could add a dialog that allows us to choose when we put a step down but we should still allow the user to change later via the Edit substep we create.
I don't think we can create something that inserts a completely different step, but we can have one step that has the ability to do both and we can pick which one we execute. Also note we still don't have the ability to edit the Panels for a step, so we have to use a new window that we call from our Edit substep to complete the step.
Hope this helps.

How can i modify a step type description?
I need to modify the description of some custom step types. I saw how this is made in the Basic Ivi step types. What i want to do is to display the current selected operation for an ivi step type as is done in the basic Ivi step type. Isaw that this is done just evaluating the vriable instrOperation and depending on the value you guys insert a name corresponding to that value.
I tried to do the same and modified a custom step's description in order to display the currently selected oparation. The problem is that i can't display any label...instead of the label i want to appear i get a "String not found in Table" message in the step's description. What table is this?...Do i need to make the changes i want in a table or i can just use some predefined labels?...this is because with simple words like FREQUENCY or INIT the description seems to work fine. What can i do to solve the problem?
This is the description i have in the step:
ResStr("IVI_STEP_TYPE", "IVI", "IVI") + " " + ResStr("IVI_STEP_TYPE", "Counter", "Counter") + ": " + ((Step.LogicalName=="") ? ResStr("IVI_STEP_TYPE", "UNSPECIFIED LOGICAL NAME", "UNSPECIFIED LOGICAL NAME") : LocalizeExpression(Step.LogicalName)) + ", " + ResStr("IVI_STEP_TYPE", ((Step.Operation==0) ? "CONF FREQUENCY" : ((Step.Operation==1) ? "MEASURE" : ((Step.Operation==2) ? "READ" : ((Step.Operation==3) ? "INIT" : ((Step.Operation==4) ? "STATUS" : ((Step.Operation==5) ? "ABORT" : ((Step.Operation==6) ? "FETCH" : ((Step.Operation==7) ? "PERIOD" : ((Step.Operation==8) ? "CONF. VERTICAL" : ((Step.Operation==9) ? "CONF. INPUT IMPEDANCE" : ((Step.Operation==10) ? "CONF.

DIGITS STOP ARM" : "INVALID OPERATION"))))))))))))))))))))))))))))
and this is the description i get in some of the steps:
Ivi Counter, "Sample Counter", String not found in tableEromero -
The ResStr function retrieves a string from the TestStand language resource files. We call this a table. The funtion requires a category and tag value name. Review the Creating String Resource Files section in Chapter 3, page 6 of the User Manual for more details.
So the strings that you are already referencing are in the IviStepTypes.ini file in the
Components\NI\Language\English directory. You could add your new strings that you require to a sister file that you would create under the Components\User\Language\English directory, or you can remove the call to ResStr and just hardcode the string with your step type if you do not want the ability to translate the string for other languages.
The call that is probably failing is:
ResStr
("IVI_STEP_TYPE", ((Step.Operation==0) ? "CONF FREQUENCY" : ...
Also, right now the call to ResStr("IVI_STEP_TYPE", "Counter", "Counter") is probably failing and just using the default value you supply in the call.

The situation I would like is to have a library of step types which sequence developers can use. Therefore if new step types need to be added, or existing ones modified - all that needs to be done is to roll out a new MyTypes.ini (for example), and the code modules/substeps.
Scenarios:
If I create types in MyTypes.ini (make sure "Attach to this file" is checked, so they get saved here). I can then create a sequence file using these step types. No problem so far.
I can open the type palette, modify the step properties, and save. When I go back to my sequence file an asterisk appears (saying it needs to be saved, even if I have opened it from scratch). The properties have been updated to reflect what is in the Type Palette. Still no problem (Type versions are the same in the sequence file and type palette).
This is where the problem appears:
If I change a step type (in the Type Palette) from using a code module to using a Post-Step substep instead (changing the module adaptor to "None") - any instances do NOT update when you open sequence files. (The same happens vice versa also).
Please note that the "Type version" listed in the sequence file DOES match that listed in the Type Palette - the properties are the same but the manner in which the code modules are called is DIFFERENT! This then can lead to to runtime errors if the old code module has been deleted for example.
The only way around this is to open EVERY sequence file that contains an instance of the step type, and make sure that you have "Apply changes to all loaded instances of this type" checked in the step type properties dialog. This is is not a good solution since files could be missed, and is very time consuming if you have hundreds of sequence files!
What I need is that the Type Palette on any particular station contains the MASTER copies of each type. These are loaded whenever a sequence file is loaded and NOT retreived from the sequence file. As discussed above this seems to work when you modify properties - but doesnt work fine if you change the way in which code modules are called.
Am I doing something wrong or is this a limitation?I had a system recently containing seven sequence files, approx 20 subsequences in each, and around 10-20 steps in each sub-sequence. Every step (except for the NI non-code module types) was an instance of a step type.
Each one of these steps had an Edit sub-step and a code module called through the code module adapter.
In order to make these into "wrapped up" step types it was decided to move the code module to a Post-Step substep (as also done in the NI-IVI step types) - so that developers cannot fiddle with the code prototype or module.
In order to do this I had to open all 7 of the sequence files, make the changes and then ensure that "Apply changes in this dialog to a loaded instances" was checked. This seems to sort of work, but some steps started causing Error 17502 (System Error) when you configure them (call the Edit substep). Over the course of the past few months I have had to effectively check every instance of a type to see if it works (deleting the step and replacing it when it doesnt). Other strange things happened like some of the step type instances now have the "None" (adapter) icon associated with them - but both still work.
The idea of creating a type-def of a step type is a good one, but frustrating that it doesnt seem to fully work. Why should the sequence file also store a version of the step-type - which is what is effectively causing this problem - why not make it so that if you dont have the step types installed in the type palette - TOUGH!

I'm wanting to add some custom step types such that they're seen when I right-click (in TestStand) in a sequence and select "Insert Step", So right now, when I do this, I see "Tests" and "Action", then "Sequence Call", then "Statement", etc. There is a little grouping bar between 'Action' and 'Sequence Call'. What I would like to do is add some custom step types above 'Tests' and 'Action' that would be in their own grouping.
I noticed that TestExec.ini has some of the information I'm looking for, i.e. TypeGroups[1] below, but I'm thinking that I'm not supposed to directly modify this file (or am I?). What's the best way to go about this cusomization?

You should just be able to type in a string expression for the name. For example, "My Customized Steps" (with the quotes).
Once you've added a group, you can click and drag steps from the list on the Customize screen and put them into your group. After you click OK on the Customize window, you should see the new folder in the Insertion Palette, and a new submenu when you right-click on your sequence and choose Insert Step.

Is there an IviSwitch step type?
I would like to use the built-in IVI step types that comes with TestStand 2.0, to control my IVI instrument drivers. I am going to use several switching drivers, and I noticed there are IVI step types for DMM, Scope, Function Generators and DC Power supplies. Is there a step type for the IVI Switch class drivers?
This will be available in TS 2.0.1 (free upgrad to TS 2.0) in a couple of months.

Add-on step types for TestStand?
I am almost certainly reinventing some wheels with Teststand by creating some basic test types.
For example, I just wrote a custom step type for taking an analog measurement from a DAQmx instrument. Surely someone has done this before, and surely someone will want to do it again. There's nothing proprietary about code that simple, and I'd be happy to give it away if there was a place to post it.
Two questions:
1. Is there an open-source repository for sharing custom step types?
2. Are there add-ons for purchase with canned step types beyond those which come with TestStand?
-ArthurHi Jigg,
I looked at Averna.com, and I don't see any add-ins available on their website. It looks like they offer services mostly.
It's a good point about TS projects being so varied and customized. However, if custom step types are well architected, as the built-in step types are, then they ought to be reusable by others.
You're right also that I can accomplish my DAQmx steps easily using an Action step with the LV adapter. My motivation for the custom step is to improve the interface for setting up such an action. In particular, when using an IO channel in TS, I have to manually type in a text string for the DeviceName value, whereas I'd like to choose from a list of global names (e.g. with the global channel list control in LV). I can get this affect by using an Enum in a wrapper VI, which maps to an array of channel constants; but this is fragile if the available channels are changed (e.g. added, removed or renamed in MAX).
Additionally, a custom step type is better than a step template for my purposes, because I can propagate changes in the step type to instances of steps throughout the test. This is incredibly valuable to me during development and debugging. It saves me time when I want to update a step that I've used many times throughout a test sequence. Although TS isn't itself a programming language, I find that I expect it to share certain traits with programming languages to facilitate development, such as type abstractions and a strict enforcement of congruency between types and instances. But I digress....
