Maintenance demanded:
•
Problem with redundant power
supply
•
C-PLUG not detected or incor-
rectly formatted
•
Program is adopted after re-
start,
(Note: After plugging in a C-
PLUG after a memory reset a
second restart is necessary.)
•
Duplicate database (internal
memory and C-PLUG)
* The LEDs LK1/LK2 flash very quickly when there is data traffic. When there is a high load. It may not be possible to dis-
tinguish the flashing from steady light.
The LEDs LK1/LK2 are also used for the node flash test.
Note
LEDs LK1/LK2 turned off when bus adapters are connected
If bus adapters are connected to the LINK for the Ethernet connection, the LEDs LK1/LK2 of
the LINK are turned off.
In this case, the LEDs of the bus adapter need to be evaluated, see section LED displays of
the bus adapter (Page 25).
