OFF Communication module is not operational
STA Green ON Communication to all slaves is established
Flashes cyclic ---
Flashes non-
cyclic
No configuration or stack error
OFF No communication
ERR Red ON Communication to one/all slaves is dis-
connected
Flashes cyclic Communication to at least one slave is
disconnected
OFF No error
STA Yellow Blinking
(synchronously)
No production data available,
no bus communication possible.
ERR Yellow
LED state
during
firmware
update
STA Green Blinking
(synchronously)
