Also, don't get confused between your wired ethernet address and your wireless address on your PC. When you do IPConfig in a command window, confirm which address is which since they are usually on different subnets. You want to make sure you use your wired IP address subnet. -
That is your Subnet MASK, not your subnet. Your subnet is 192.168.0. You need to make the subnet match between the PC and PLC (the first 3 octets must be the same and the 4th octet different). The subnet of the PLC, as you show above is 10.2.5. Also, are you certain that 10.2.5.83 is the IP address of the PLC? Even so, go into UniApps and change it to 192.168.0.xxx (anything other than 71). Or, you can go into your PC network settings and change your PC IP address to 10.2.5.xxx (anything other than 83). Once you do that you should be able to communicate if you are plugged into the correct port with a crossover cable or through an ethernet hub.

Not sure how to make that determination but when I do IPconfig in CMD, I see my subnet listed as 255.255.255.0 and that of the PLC listed as 255.255.0.0 (not the same). On the PLC IP panel settings in UniApps, I see the subnet mask listed as 255.255.255.0 same as mine. -
Is your PC on the same subnet as the PLC (10.2.5.xxx)? Also, are you plugged into the correct Ethernet port on the PLC? Are you using an Ethernet hub or a crossover cable?
