Currently the OPC UA sensor supports only RSA 2048. It would be highly advantageous to also support RSA 4096 as a lot of plant control systems only support RSA 4096 for enhanced security.

Much appreciated and thank you for the prompt response to this. It will greatly help us integrate our Honeywell DCS Plant control system into PRTG for specific Experion points and SCADA points monitoring.

I also wanted to mention that we have a new product for industrial customers, the PRTG OPC UA server. With this, you can export data from PRTG to the PRTG OPC UA server and read it via OPC UA and add it into SCADA systems.
