Determining the cause of error

The error type and number may be determined from the LEDs FS and FN, which are to be found above
the supply terminal of the IL PB BK. If diode FS lights, the number of flashes of FN shows the error type.
If diode FS is off, the number of flashes of FN shows the error number.
Error type and number are simultaneously notified via the PROFIBUS to the control system.
Example:
LED FS lights and LED FN simultaneously flashes three times. Then LED FS extinguishes and LED FN
flashes four times (error type 3, number 4). The cause of error is the use of an INTERBUS Loop-1
module which is not permissible.

Explanation
Supply voltage present in main circuit for IL PB BK, logic
supply and interfaces.
Supply voltage present in segment circuit.
No data exchange with master.
Selects function of LED FN: FS lights: FN shows the error
type. FS does not lieght: FN shows the error number.
The number of flashes indicates the error type or error
number, depending on whether FS lights or not.
