9.2 The essernet
®
The essernet connection of the various units in the network can be checked with this diagnostic line.
®
The essernet diagnostic line (L:xxx) indicates which connections are functioning correctly and which have
malfunctioned. Non existent units/ control panels are represented by the character "?".
The status display at the beginning of the line (0,S,E or B) indicated whether data calibration is in progress
between two control panels. This is always the case when signals are updated in the essernet
when a switched off control panel is switched back on or when a new control panel is integrated in the essernet
network and its data is automatically updated. Which control panel is conducting this data calibration can be
determined by the two-digit control panel number (part: xx).
