You could use a serial to ethernet converter, or replace the card with a 6ES5135 0TA?? Ethernet module. Make sure you are sitting down when you get the price for the Ethernet module as it is going to hurt!!!

Definitively: No chance for an upgrade. CP 525 cards are for serial communication (V24 and 20mA current loop) only. What you need for ethernet communication is a CP535 or CP1430 card.
there a 3rd party card INAT S5 TCP/IP coms card that is designed for S5, TCP/IP and H1 (AUI) ports. Haven't used it though just run accross it in the Web.
