The LEDs indicate the operating state of the module.
The LEDs on the module are divided into three groups:
ƒ Module status indicators (Run, Error, Stop, Init)
ƒ System bus indicators (A, B)
ƒ I/O indicators (DO 1...32, Field)
When the supply voltage is switched on, a LED test is performed and all LEDs briefly flash
simultaneously.
Definition of Blinking Frequencies
The following table defines the blinking frequencies of the LEDs:
Name Blinking Frequencies
Blinking1 Long (approx. 600 ms) on, long (approx. 600 ms) off
Blinking2 Short (approx. 200 ms) on, short (approx. 200 ms) off, short (approx. 200
ms) on, long (approx. 600 ms) off
Blinking-x Ethernet communication: Flashing in sync with data transfer

OPERATE (only with processor modules)
Run Green
Off Module not in RUN,
observe the other status LEDs
On/Blinking1
Internal module faults detected by self-tests, e.g.,
hardware, software or voltage supply.
Fault while loading the operating system
Error Red
Off Normal operation
On Module state:
STOP / VALID CONFIGURATION
Blinking1 Module state:
STOP / INVALID CONFIGURATION or
STOP / OS_DOWNLOAD
Stop Yellow
Off Module not in STOP, observe the other status LEDs
On Module state: INIT, observe the other status LEDs
Blinking1 Module state: LOCKED, observe to the other status
LEDs
Init Yellow
Off Module state: neither INIT nor LOCKED, observe
the other status LEDs
