cannot load eds file

[PaulG.]

Following the instructions in this thread I am still unable to download an EDS file into my DeviceNet master interface. Regardless of what EDS file I enter (and I have about a hundred to choose from) I get the same error message "The device has 4 I/Os and the EDS file has none" so I don't think it's getting anything.

 Hello PaulG,

What version of LabVIEW and what version of the DeviceNet driver are you using? What hardware are you using?

The link below details the steps that need to be taken to add a DeviceNet Master and DeviceNet Slave to a LabVIEW Project as well as loading an EDS file for a slave device. The steps are essentially the same as in the forum post you are following but you may want to make sure these are the steps you followed.

DeviceNet Cards that Support Importing EDS Files

LV2014 and DeviceNet 14.5. I tried your solution already as stated in my first post. Also, I cannot seem to populate the EDS files list with additional EDS files in the datasheet menu. No matter what EDS file I load I get the same error message which tells me the EDS file might not be getting loaded at all:

"The I/O in the configuration is different from the supported I/O in the device. Please change the device data sheet. Here are the details:

Error: This device supports a different I/O size. The COS Output size is 0 (in the device) and 4 (in the configuration).
Warning: This device supports the additional mode, Cyclic. It isn't defined in the slave configuration.

You can click "Verify the device" again to verify that the device supports the configured I/O configuration."

Hello PaulG, 

What hardware are you using?

PCI 8532. I found about a half dozen EDS files for my driver but none seem compatible with my drive. I'm also not able to populate more than one EDS file in the Datasheet menu. This is really flakey stuff.

I am still using the NI-DNET VIs and I scan via explicit messages at program start the available devices, input/output sizes etc..., before starting the I/O connection. In this case no EDS files are needed.

One time I needed to use EDS files with non NI hardware and there was a problem with one of them. There is pretty useful EDS editor at the ODVA website, EZ-EDS™ which helped me a lot. The software is free, but you need to register in order to download it. It makes it easier to edit the files, compared to a simple text editor. Maybe you can just add some missing parts to the files and make it work.

Contacted ODVA and they said EDS files were not required and just made it easier to set up. I didn't need it since the motor controller and DeviceNet interface firmware is well documented. I got it working. That's all that mattters.  Thanks for your help.
