PCo 2.3 and RSLinx tags browse

Hi to all,

I installed the PCo 2.3  with the last patch. I'm using MII version 12.0.

I installed, on the same machine, the PCo 2.3 and the RSLinx version 2.57 con professional license.

IN Rslinx i configured a driver ETH, i setted the IPaddress of the PLC and then, I created a topic configuration. From RSLinx i'm able t see all tags available.

When i try to browse the taglist from an agent instace ( Subscription Items) i receive the error: "Browsing failed, check the connection and try again. [Error during browse request].

Any other experiences or ideas?

Thanks

Andrea
