Start-up behavior of the Fieldbus Box
After power up, the Fieldbus Box checks its state, configures
the IP-Link (if present) and refers to the extension modules to
create a structure list. If the Fieldbus Box contains a
decentralized controller (IL230x-C310) the local PLC is started
once the structure list has successfully been created.
The I/O LEDs illuminate and flash as the module starts up. If there
are no errors, the I/O LEDs should stop flashing within about 2-3
seconds. If there is an error, then the LED that flashes will
depend on the type of that error (see Diagnostic LEDs).
