Courier is the communication language developed by Schneider Electric to allow remote interrogation of its range of protection relays. Courier works on a master/slave basis where the slave units contain information in the form of a database and respond with information from the database when it is requested by a master unit.

The relay is a slave unit which is designed to be used with a Courier master unit such as MiCOM S1/Easergy studio or a SCADA system.
