How to work on loopback in one PC?
– I want to test of SECS communication in my PC, but I could not log with this software when I use same IP address(or 127.0.0.1).
How to do something?
You can use Microsoft(R) Loopback Adapter.
This software will be not able to log loopbak(ex.127.0.0.0,localhost etc.), but it will be able to log with ‘Microsoft(R) Loopback Adapter’.

For more information, please see here(“How to set to test on loopback”).
