8.13 sercos Slave
For the sercos Slave protocol, the communication LED
S
as well as the
Ethernet LED
L/A
can assume the states described below. This description
is valid from stack version V3.1.
LED
Color
State
Meaning
Duo LED red/green
(orange = red/green simultaneously)
(green)
On
CP4: Communication phase 4:
Normal operation, no error
(green)
Blinking (2 Hz)
Loopback:
The network state has changed from „fast-forward“
to „loopback“.
Flashing
(3 x green/3s)
CP3: Communication phase 3
(2 x green/3s)
CP2: Communication phase 2
(green/orange)
(1 x green/3s)
CP1: Communication phase 1
(orange)
On
CP0: Communication phase 0
Blinking (2 Hz)
HP0:
Hot-plug mode (not yet implemented)
(1 x orange/3s)
HP1:
Hot-plug mode (not yet implemented)
(orange/green)
(2 x orange/3s)
HP2:
Hot-plug mode (not yet implemented)
(orange)
Flashing (2 Hz)
Identification:
Corresponds to C-DEV.Bit 15 in the Slave’s
Device Control indicating remote address allocation or
configuration errors between Master and Slaves (for details
refer to sercos Slave V3 Protocol API Manual).
(green/red)
Flashing (2 Hz,
min. 2s)
MST losses
≥
(S-0-1003/2):
Depends on IDN S-0-1003 (for
details refer to sercos Slave Protocol API manual).
Corresponds to S-DEV.Bit 15 in the Device Status indicating a
communication warning (Master SYNC telegrams have not
been received).
(red/orange)
Flashing (2 Hz)
Application error (C1D):
See GDP & FSP Status codes class
error, (see sercos Slave V3 Protocol API Manual).
(red)
Flashing (2 Hz)
Watchdog error:
Application is not running (not yet
implemented)
(red)
On
Communication Error (C1D):
Error detected according to
sercos third generation Class 1 Diagnosis, see SCP Status
codes class error (see sercos Slave V3 Protocol API Manual).

Duo LED red/green
General
name:
COM 1
(off)
Off
This LED is not used.
LED green
(green)
On
Link:
The device is linked to the Ethernet, but does not
send/receive Ethernet frames.
(green)
Flickering (load
dependant)
Activity:
The device is linked to the Ethernet and sends/receives
Ethernet frames.
L/A
Ch0 & Ch1
(off)
Off
The device has no link to the Ethernet.
LED yellow
Ch0 & Ch1
(off)
Off
This LED is not used.
