Explanation
RUN
Lit (green)
ET 200C; DO 8
DC 24V/0.5A or ET 200C;
DO 8
DC 24V/2A is in the RUN mode (power
supply switched on)
U
L
Lit (green)
Load voltage for outputs present
BF
Lit (red)
Either
The monitoring time has elapsed without the
ET 200C; DO 8
DC 24V or the ET 200C;
DO 8
DC24V/2A being addressed (because
the connection to the IM 308-B is lost or
IM 308-B is in STOP mode)
or
ET 200C; DO 8
DC 24V/0.5A or ET 200C;
DO 8
DC 24V/2A was not parameterized
during startup or a restart
DIA
Lit (red)
Group diagnostics of the outputs:
Wire break, short-circuit
1
/overload or
undervoltage at the outputs
0, 1, 2, 3, 4, 5, 6, 7
Lit (green)
Output active
(Status LEDs of the
outputs)
Flashes (red)
Short-circuit at the output
Lit (red)
Wire break at the output
4 LEDs lit (red)
2
Internal blowing of fuse
3
8 LEDs lit (red)
2
Either
Undervoltage of the load voltage supply
or
Internal blowing of fuse

1
The diagnostics message remains for a further 20 s (approx.) in the case of ET 200C; DO 8
DC 24V/2A after the
short-circuit has been eliminated (e.g. when an output is reset).
2
Not with ET 200C; DO 8
