yellow
Flashing irregular (*)
Hardware or heavy runtime error detected
green
On
Communication is running, the device has established at least one
configured fieldbus connection
green
Flashing cyclic at 5Hz
No error in the configuration found, communication is stopped or ready
for communication but no connection to any slave
green

Power Up: Configuration missing or faulty, device needs commission-
ing, Runtime: Host Watchdog timeout
SYS
-
Off
Device has no power supply or hardware defect
yellow
On
Devise is holding the PROFIBUS Token and is able to transmit tele-
grams
yellow
Flashing irregular (**)
Devise is sharing the PROFIBUS Token with other Master devices in
the PROFIBUS network
red
On
Device has found a communication problem to at least one PROFIBUS
DP Slave or has detected a short circuit
