Manually interpreting EDS File

[AlfredoQuintero]

AmazingNoob:The Assembly instance 100 is not writable. the device is telling you that the set attribute single is not supported.
you have to find out how it was configured.
The output instance has to be a different one.
My advice is, if you are in the dark, do GetAttribute single from 100 through I don't know, 120 or until you get invalid path which means the instance is not supported.
For the instances for which you do get a reply to getAttribute single, try SetAttribute single with the same byte numbers that the response to the GetAttrSing gave you. Until you find which is the correct output assembly. I think the EDS file does not reflect the actual configuration of that device.

What is the documentation for this product?
I can have a look at it. Maybe what you need to know is cryptically explained somehwere in the documentation.

I believe i got all the info that I need. I used the codesys tool, and was able to prove out the information i need. The molex tool only does explicit, and the eip hardware i got only work with implicit connections, and I am unable to poke value to it through set attrib single.

Good to know CODESYS was helpful.

Would you be so kind as to delete the hyperlinks in the quoted answer? Not sure if okbyee56 is a spammer just yet but the links are suspect.

Or you can use TwinCAT which works for 7 days after installation without a license. If you uninstall and reinstall TwinCAT it will work again for 7 days.

Just to clarify, you don't have to uninstall and reinstall TwinCAT after the trial expires. Just drill down to the license information in TwinCAT and click on the "7 Days Trial License" button. It will prompt you to enter a captcha and then a new 7-day trial period will begin. You can do this infinitely. This is for TwinCAT 3.

The Waterboy, sorry, I did not realize there were those links in that post. I am unable to edit them after all these hours have passes. Needs to be done by a moderator.

That is so much easier... Thanks for clarifying. Since I have a TwinCAT PLC and a USB dongle which I use for PCs, I have not used the evaluation in a long time..
