Hello,

I am working on using Factory IO with eclipse 4diac via UPC UA. 4diac forte uses the open source UPC UA modul open62541.  
Connection Factory IO with my UPC UA server works fine, but I can not see any nodes in Factory IO.  
I use a boolean and an Int16 node for testing. Both are not visible in Factory IO (but i can see them in UaExpert).  
Do the nodes have to be in special folders or have a special data type (other than boolen or Int)?

Hi,

The OPC UA driver searches for nodes that can represent variables, so it should be able to find these.

Are you browsing the OPC server after connecting to it? Are you defining any node filters?

In my case show the nodes:  
Server:  
OPCUAServer@DESKTOP-8C9  
5251 (UA) (32)

OnlineAccess  
NodeVersion  
InputArguments  
OutputArguments  
NamespaceUri  
NamespaceVersion  
…cePublicationDate  
IsNamespaceSubset  
StaticNodeIdTypes  
…ericNodeIdRange  
…ringNodeIdPattern

NamespaceUri  
NamespaceVersion  
…cePublicationDate  
IsNamespaceSubset  
StaticNodeIdTypes  
…ericNodeIdRange  
…ringNodeIdPattern

but not show my nodes.
