STATUS LED
STATUS LED (
1
) reflects status of Powerlink communication.
LED state
Description
Off
Initializing or not active
Green flashing (on 50 ms, off 50 ms)
NMT_CS_BASIC_ETHERNET
Basic Ethernet state: no Powerlink traffic
Green single flash
NMT_CS_PRE_OPERATIONAL_1
only asynchronous data
Green double flash
NMT_CS_PRE_OPERATIONAL_2
asynchronous and synchronous data, no PDO data
(any process data sent is declared not valid and re-
ceived process data must be ignored)
Green triple flash
NMT_CS_READY_TO_OPERATE
ready to operate, asynchronous and synchronous da-
ta, no PDO data (any process data sent is declared
not valid and received process data must be ignored)
Green
NMT_CS_OPERATIONAL
fully operational, asynchronous and synchronous da-
ta, PDO data is sent and received
Green fast flashing (on 200 ms, off 200 ms)
NMT_CS_STOPPED
interface stopped (e.g. for controlled shutdown),
asynchronous and synchronous data, no PDO data
(any process data sent is declared not valid and re-
ceived process data must be ignored)
Red
If ERROR LED (
2
) also red: fatal error
►
If STATUS LED (
1
) and ERROR LED (
2
) are red contact HMS Industrial Networks technical
support.
ERROR LED
LED state
Description
Off
No error
Red
Recoverable error
If STATUS LED (
1
) also red: fatal error
►
If STATUS LED (
1
) and ERROR LED
(2
) are red contact HMS Industrial Networks technical
support.
Link/Activity LED
LED state
Description
Off
No link
Green
Link, no traffic
Green flashing
