How to get ip address Schneider PLC controller TM218LDAE40DRPHN?
Your MAC (note capitals) address to IP (note capitals) address conversion is correct. 

Check your IP configuration settings:


CMD window, ipconfig.


If you don't see an IP address starting with 10.x.x.x and subnet mask 255.0.0.0 then that's at least part of your problem.

To ping the PLC do the following:


Set PC IP address to another address in the same subnet. Since the PLC's subnet is 255.0.0.0 this can be any valid address in the 10.x.x.x range other than the PLC's. Try 10.1.1.1.
Set the PC's subnet mask to 255.0.0.0.
Gateway settings do not matter.
Connect the PC to the PLC. Check the Ethernet port LEDs light up.
ping 10.10.161.157.


There is a small chance that you don't have automatic cross-over on your network interface card. In that case you have two options:


Use a cross-over Ethernet patch cord.
Use a router, set it's LAN IP address to 10.1.1.2, subnet to 255.0.0.0 and plug both devices into LAN ports. Try to ping again.
