Section 13 Establishing connection and verifying the
LON communication
About this chapter
This chapter explains how to set up LON communication and how to verify that
LON communication is up and running.
13.1 Communication via the rear ports
13.1.1 LON communication
LON communication is normally used in substation automation systems. Optical
fiber is used within the substation as the physical communication link.
The test can only be carried out when the whole communication system is installed.
Thus, the test is a system test and is not dealt with here.
The communication protocol Local Optical Network (LON) is available for 670
IED series as an option.
