1 pulse
2 pulses
Blink fast
Blink slow
1 pulse: ProfiBus link established, controller link NOT established yet
(Controller state machine not in Regular data exchange). This
situation could be normal in the first 45 seconds after the interface
power on (Controller address searching phase) or after the controller
power-on.
You have this error if the special mating connector is not placed on
the serial connector J6 (see paragraph "Configuration").
2 pulses: ProfiBus link not established yet (ProfiBus state machine
not in Regular data exchange). This failure has priority (in the
indication) over the previous.
Blink fast: Gateway fail (internal check) or wrong address set
(address > 0x7D or address not stable during power-on).
Blink slow: Gateway operating properly.
