Loopback test
Running a loopback test checks the functions of the control section and communication section in the
unit.
Note:
If you conduct an external loopback test when other nodes are communicating on the LAN, there is a
chance that an error may occur. Either take steps to ensure that other nodes will not communicate or
disconnect the other nodes before performing an external loopback test.
