Hello,

Is there any way to get some information about the USB location of a PLIN-USB using the PLIN-API?

We're using two adapters on one PC and we would like to simplify to replacement in case of a breakdown.
We know that one way to accomplish such requirement is editing and using the Hardware IDs, but this is always a manual setup.
Our idea is to use the USB location to figure out which PLIN is connected to which bus.

Thanks in advance!

You could set a unique Hardware ID for each Device within the Control Panel APP. With the Software API you could read the ID back, and so could decide wich PLIN-USB Device is on which LIN Channel.

At the moment this is the only solution. There is no "fixing" of the Device to a LIN Channel (like we have implemented it on the CAN units)

Thank you for the reply.

I'm currently implementing the update of the HardwareID with the API but the ID is not really updating.

When I execute the SetHardwareParam everything goes fine, but when I read it back the value doesn't update (I've confirmed with PLIN-View PRO).
Any ideas?

Have you test if you could set the ID with Control Panel - as we wrote in our last post? If yes, could you read it with your code back?
Does this work ? We could give you a short C code example how to Set & Get the parameter - simply send us a e-mail to support[at]peak-system.com

Yes it works fine, if I set the ID with PLIN-View PRO, I can read it back in my app.

I found out the problem, I was setting wBuffSize to 0 as you can see in the picture of my last post. Now that I understand the purpose of such parameter it's weird that the method accepts it to be 0 without "complaining".

Thank you for your support.

It is a global function that call different subfunction depending on the Parameter (which make it flexible for new features without changing the API)
So a validation is nearl impossible, because there exist parameters where a zero is OK.
