Self test:
The module runs through a self
test after it is switched on. See the descrip-
tion of the “MS” LED and the description of
the “Self test” status.
Red/green/off
Flashing sequence:
red/green/off
Flashing sequence:
The flashing se-
quence identifies the adapter visually. The
scanner can start the flashing sequence in
identity object 1 of the adapter. The MS
LED and NS LED go through the flashing
sequence simultaneously.
Red
Flashing (1 Hz)
Connection timeout:
An IP address is con-
figured, and, for an Exclusive Owner con-
nection for which this module is the destina-
tion, the time limit has been exceeded. The
NS LED is not permanently reset to green
until all Exclusive Owner connections
whose time limits were exceeded are
reestablished.

(1 Hz)
The LED switches on and off in phases at a frequency of about 1 Hz:
on for 500 ms and then off for 500 ms.
Rapid flashing
green/red/green
The MS LED or NS LED lights up green for 250 ms, then red for 250 ms, then green
again (until the test is completed).

Flickering
(load-dependent)
The LED indicates high ETHERNET activity by switching on and off at a frequency of
10 Hz:
“On” for 50 ms and then “Off” for 50 ms.
The LED indicates low ETHERNET activity by switching on and off at irregular intervals.
