4.3 LEDs of the CAN 300 PRO
The LEDs of the CAN 300 PRO can also be a great help.
The “SF” LEDs should not be lighted; otherwise there is a system
error.
If the “BF” LED is lighted, a CAN error is still present. Check the
cabling and the CAN baud rate of all bus nodes. You will find
more detailed information on the debug screen in the “Controller
status” area.
The “Rx” and “Tx” LEDs show the traffic on the CAN bus. If the
PLC is in the RUN state and a valid project has been imported,
both LEDs should flash or shine steadily, depending on the CAN
traffic.
The “ON” LED flashes until the PLC is in the STOP state of the
master of the CAN 300 PRO was not yet able to enter cyclic
operation. The “ON” LED shines steadily if the master has
initialized the slave devices and has entered cyclic operation.
If the “ON” LED flashes after the PLC has started, an error has
occurred during start-up and initialization of the slave. Also check
what the cause of this could be on the debug screen.
