Scan Engine & EtherCAT Custom Device Feedback

[backpackerike]

Stephen,

Do I actually have to install something or just put the scan engine file in the right location? I don't see an .exe file or anything to install. I deleted the old folder and installed it again. I have the same errors come up.

Hello,

No there is no installer.

Follow these steps:

1. Delete the currently installed scan engine custom device content from your "<Public Documents>\National Instruments\NI VeriStand 20xx\Custom Devices" directory
2. Visit NI VeriStand Add-On - Scan Engine and EtherCAT and download the device zip file again that is specific to your version. Aka... the 2011 file for NI VeriStand 2011... etc.
3. Unzip the contents of that zip file somewhere temporary like your desktop
4. Open the readme.txt and follow the installation instructions

I'm hoping this erase, redownload, and reinstall clears up any sort of corruption

Add-On Installation Instructions:
----------------------------------------------------------------------------------------------
*With NI VeriStand closed*:

1) Copy the "Scan Engine" directory into your "<Public Documents>\National Instruments\NI VeriStand 20xx\Custom Devices" directory.
Note: The location of <Public Documents> will vary depending on your operating system:
Windows XP: C:\Documents and Settings\All Users\Documents
Windows 7 or Vista: C:\Users\Public\Documents

**Optional Error Code Installation**
If you want the appropriate text for the custom error codes shown below to be displayed by NI VeriStand and the Real-Time Target, follow these steps:
1) Copy the "scanengineveristand-errors.txt" to <Program Files>\National Instruments\Shared\Errors
2) FTP the "scanengineveristand-errors.txt" to your Real-Time target (you can use windows explorer and type in "ftp://<ip>") into the "\ni-rt\system\errors" directory.

These are the directions that I followed. I still get:

Missing subVI Scan Engine Custom Device.lvlib:Host - Get Module Data.vi in VI Scan Engine Custom Device.lvlib:Host - Get Slaves.vi.
Missing subVI Scan Engine Custom Device.lvlib:Host - Get Module Data.vi in VI Scan Engine Custom Device.lvlib:Host - Get HW Config.vi.

OK I'm going to set up a clean virtual machine to test with

[StephenB]

OK I've reproduced it

So I installed NI VeriStand and the Driver's associated with it... then I saw the error and the linker tester EXE said this:

"Missing subVI Scan Engine Custom Device.lvlib:Host - Get Masters.vi in VI Scan Engine Custom Device.lvlib:Host - Get HW Config.vi."

Then I installed NI Industrial Communications for EtherCAT 2.6 and the error went away and it worked great. That is a little unexpected since I thought you didn't need EtherCAT driver for that button... but apparently you do. I'll add that to the known issues list.

So it appears you have some driver issue. I would try repairing your EtherCAT driver and possibly your NI-RIO driver.

I repaired my NI Industrial Communications for EtherCAT 2.6 and it did not affect anything. SO I re installed it, which didn't work. I repaired my NI-RIO driver and that did not affect anything either

[StephenB]

Hmm... is there another computer there that it works on? Something is certainly wrong with yours. I want to try to isolate the issue.

Thanks for your patience.

My supervisor set up our PXI system and made a Veristand program to test it out. He got the scan engine to work when creating the file. This was last week.

I decided to uninstall all of the National Instruments products on my computer and reinstall them from the CD. Now my scan engine works. I don't know what exactly caused the problem, but atleast its fixed.
