Figure 8-2
Station with example diagnostic indicators (states A to C)
Figure 8-2 shows a station with two example error states. It shows that an I/O error has been
detected at terminal 5 or that terminal 4 has failed and shows the behavior of the diagnostic
indicators on the adjacent terminals.

Error:
Short circuit at terminal 4 (IB IL 24 DO 2-2A)
Effect:
field multiplexer:

LED are on (see Table 8-3, no. 12)
Opposite station:

Terminal 4:
D
LED flashes at 2 Hz
Other terminals:
Remain unchanged
Alarm relay:
Not activated
Error:
Local bus has been interrupted after terminal 3 and before terminal 4
Effect:

LEDs are on (see Table 8-3, no. 7)
Opposite station:

LED is flashing (see Table 8-3, no. 7)
Terminal 4:
D
LED flashing at 4 Hz (bus error)
Other terminals:
D
LEDs on all other terminals flashing at 0.5 Hz *)
Alarm relay:
Activated

If the bus error is located on the forward path of the local bus, the devices before the
fault location flash at 0.5 Hz. If the error is located on the return path, irregular flash-
ing (switching off for short periods) can be observed on the LEDs of the devices be-
fore the fault location.
