HIMA X-AI3251 Digital Output Module

HIMA X-AI3251 Digital Output Module

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

3.4.3 Module Status Indicators

These LEDs are located on the front plate, on the upper part of the module.

LED Color Status Description

On Module in RUN, normal operation

Blinking1 Module state:

STOP/OS_DOWNLOAD or

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

System Bus Indicators

The system bus LEDs are labeled Sys Bus.

LED Color Status Description

On Physical and logical connection to the system bus

module in slot 1.

Green

Blinking1 No physical connection to the system bus module in

slot 1.

A

Yellow Blinking1 The physical connection to the system bus module

in slot 1 has been established.

No connection to a (redundant) processor module

running in system operation.

On Physical and logical connection to the system bus

module in slot 2.

Green

Blinking1 No physical connection to the system bus module in

slot 2.

B

Yellow Blinking1 The physical connection to the system bus module

in slot 2 has been established.

No connection to a (redundant) processor module

running in system operation.

A+B Off Off Neither physical nor logical connection to the

system bus modules in slot 1 and slot 2.
