Information regarding Fanuc OPC Namespaces

Hello, I write this because we are developing a software that includes an OPC client to communicate with robots using this protocol.
Actually ,we are trying to connect with a Robot Fanuc CRX-10iAL towards its OPC UA server.
We are having issues with certain variables, and we need to know one specific Fanuc namespace, in order to study which datatype are causing this issue. The namespace is: http://fanuc.com/uaToolkitEmbedded

Someone knows how to extract NodeSet2 XML file associated to that namespace?. I have trying to use uaExpert but I have issues trying to extract it.

Another choice is to contact with Fanuc support. I have tried to communicate with different Fanuc regions, but they don't know to how to answer with that problem, maybe these regions are not expert in this specific OPC topics. Does someone know what Fanuc region deals with this kind of OPC protocol issues?.

Best regards.

Francisco Jiménez.
