We got about 20 OP's all connected via MPI to PLC and via network card to our intranet.Problems is that you can 'hack' these winCE based devices using telnet.Telnet is using port 23 but how do you block this port or protect it via a user/password Greetings Eric

I am sure that in previous versions (2004) this was availiable as a stand alone program ( with tab pages for each function ( Back-Up / Restore /OS-Update etc) In the old versions the only option was 'UPS' but in version 2007 there is the added ' TELNET block. Bye Eric
