LED signaling Power LED The power LED indicates the current status. Normal operation In normal operation, the green power LED flashes briefly once per second. Case of an error If an error has occurred, the LED turns red and signals an error number.In the following figure, the error number 3 is signaled. The following table shows the meaning of the error numbers. Flash rate Error 1 General 2 Voltage 3 Temperature 4 Overcurrent 5 Controller 6 Watchdog-Reset Note: For each error that occurs, a more precise error code is stored in object 1003h. Tip: You can switch off the power LEDs with 3250h:09h. PROFINET LEDs Bus Failure (BF) LED behavior Status Permanently on No link status available Flashing Link OK, no active communication connection to PROFINET controller Permanently off No active communication with PROFINET controller System Failure (SF) LED behavior Status Permanently on PROFINET diagnosis present Permanently off No PROFINET diagnosis Link The LINK LEDs indicate the status of the physical Ethernet connection on PROFINET ports 1/IN (left) and 2/OUT (right).
