Getting an error when sending user Identity and certificate was created by hcrowe
Hi I am currently trying to connect to a Siemens 1500 PLC. Attached is the error I'm experiencing using Connectivity Explorer. I'm using 2018.2 of the OPC labs components. Even if I set the PLC to except any client certificate I still cant connect. If I turn off security settings in the PLC, and only connect with the username and password it works fine. The odd thing is when doing my testing if I monitor the packets using wire shark I get the error, but it doesn't seem to even be trying to connect to the PLC. If I use commserver OPC UA Viewer I can connect using any client certificate with no problem.

Hopefully you can point me in the right direction.

Thanks,
