2.1.1
PROFIBUS AND OM LINE INTERFACE STATUS
After a switch-on the Profibus card initialises, tests itself and then connects to the ProfiBus interface.
Initially during the testing and connection all LEDs are on. Red LEDs flash. The display reads: „PB“. In instru-
ments with 6 digit display it reads
„99“ (instrument with internal ProfiBus card) and the address of OM instrument divided by space. In instruments
with 4 or 3 digit displays only the ProfiBus address is shown. Profibuss address is entered directly into the
instrument’s menu. If the instrument is set for a mode, which cyclically reads or sets an OM xxx device, LEDs
„D1“ a „D2“ start flashing alternatively.
In a mode in which the OM xxx is set in a single step, or when information is read out from the OM ProfiBus
card only LED „D2“ flashes, signalling that the ProfiBus communication line is on.
In the event of an error LED „D3“ lights up, indicating an error as per table.
