Device Descriptor with Fieldbus

[AlanJ]

Hi,

I am using the .NET API with a PCI Fieldbus card. It seems that the API won't work if a Device Descriptor is not loaded. But a Device Descriptor has to be changes every time my Fieldbus device firmware is changed (i.e. when the indexes are changed). Other people in my company are using either the older API (pre-.NET) or tools such as NI-Dialog which don't require a Device Descriptor. They are able to access parameters by index.

Is it possible to setup the Fieldbus card or the .NET software to not require a Device Descriptor?

Hi,

You can implement your own function, for example, GetDescriptor(index) using existing APIs. When descriptor is needed, pass this function as parameter.
