Hi,
I have a Mitsubishi FX5U PLC where I cannot established communication via ethernet port of my computer. Search all videos and follow all the necessary but to no avail. Anybody can please provide solution?

If you are connecting with a direct cable from the PC to the PLC, the cable will probably have to be a crossover cable.

Another solution is to connect through a hub/switch so the cables can be normal, not crossed.

For FX5U you don't need crossover cable. Default IP is 192.168.3.250

As Goghie has pointed out, if the default IP is 192.168.3.250 then make sure your PC is set to say 192.168.3.xxx (1-511) but not 250. Subnet perhaps 255.255.0.0
