YASKAWA PROFIBUS-DP 1000 Series Technical Manual page 9

Option LED Display
The option has four bicolor, red/green LEDs to relay information about power, communication status, and errors. The
operational states of the LEDs after completion of the power-up diagnostic process are described in
2 seconds for the power-up diagnostic process to complete before verifying the states of the LEDs.
