Hi,

I try to connect to a Wago SPS (750-8202) but I always get an exception: Bad_OutOfMemory (0x80030000) “Not enough memory to complete the operation.”
Same is true for the Prosys OPC UA Client. When I use the UaExpert as client or Eclipse Milo as SDK it works.

I try to connect with the NONE:NONE profile and tried to turn off every additional feature like a status listener.

I have no clue how I proceed. Do you have any idea what could cause the failure? Did you coincidentally tested the SDK with a WAGO SPS?

Here is the stack trace….

Looks like the secure channel opening phase causes an OutOfMemory in the server for some reason. So you will need to find out why the server fails to the connection attempt. I don’t remember us testing against any WAGO devices at the IOP workshops and they don’t have any OPC UA certified products so far.
