LED indicationLED 1 (power supply): On = operating, fast flash = cold start, slow flash = HCIR loading active
LED 2 (collective alarm): On = internal fault, flashing = no PROFIBUS connection
LED 3 (status process bus): flashing = PROFIBUS receive channel active
LED 4 (status service bus): flashing = service bus receive channel active
LED 5 (operating mode): flashing 1 (1:1 ratio) = active, normal operation; flashing 2 (7:1 ratio) = active, simulation
LED 6 (status process bus): flashing = PROFIBUS response channel active
LED 7 (status servicebus): flashing = service bus response channel active
