Start-up behavior
When the BC9191 is switched on it checks its state, configures the K-bus, creates a configuration list based on the connected Bus Terminals and starts its local PLC.
When the BC9191 starts up, the diagnostic LEDs light up and flash.
In an error-free state, only the following green LEDs should light up after approx. 15 seconds:
- PLC LED
- Power LED Vs
- Power LED Vp
- TC/DC LED, only if TwinCAT configuration is active
- K-bus RUN LED, only if the BC 9191 has been extended with Bus Terminals
The position of the LEDs or which diagnostics LED flashes in the event of an error can be found in the chapter Diagnostics LEDs.
