For the 5/40, you will need to use the EthernetIPforPLC5Com driver. However, it still may not support Ethernet/IP. There are 2 way to check if it does. On the front of the processor or Ethernet card, there is typically the Ethernet/IP logo. Or if you use RSLinx and setup and Ethernet/IP driver, then go to RSWho to see if it shows up in the browse.
