Thanks again=)īut I've met a next problem.
I do not familiar with principles of networking so I did not know that it was impossible to connect with difference masks. Actually laptop couldn't find it because it had IP adress like 192.168 etc. Make sure the ethernet port on your PC is configured for the same subnet as the plc ethernet card.
If the processor is v21 you'll have to have RSLinx 3.6 Also your version of logix5000 must match the processor firmware. Make sure you're using rslinx classic 2.8 or better. In Logix5000 go to the comm tab, open the driver, drill down to the cpu, and select "Upload" Clicking on it should show the back-plane and further down the cpu. There should be a "+" box beside the Ethernet card. You can right-click on the Ethernet card and be able to bring up a configuration to change the IP address if needed. The card should show up as the ENBT, ENT2, etc. You can use a crossover cable if the Ethernet card isn't on a network switch. Once the driver is running you should be able to "browse" the network under the Ethernet/IP driver using "RSWho". You can select which of your Ethernet ports on your pc to use if needed. There isn't any configuration for the driver on the plc side. Your driver in RSLinx Classic should be the Ethernet/IP not the Ethernet devices. I'm guessing your Ethernet card is a 1756-ENBT or ENT2.
