# Meaning
Description
1. No device communication
No device physically connected OR message CRC error
2. Wrong device connected
The connected device Slave ID is NOT the right one
3. Device not initialised
The connected device has not been correctly initialised at the
end of manufacturing (where applicable - see device dependent sections)
4. Internal configuration map error Software configuration tables bug
5. Wrong parameter number
The requested parameter number doesn’t exist (only for writing operation)
6. Wrong parameter value
The parameter value is not allowed (only for writing operation)
7. Command not executed
The command is correctly received by the EP010 but it’s not possible to
send it to the device (e.g. the device is not connected).
8. Watchdog fault
Start-up diagnostics
9. Modbus UART fault
Start-up diagnostics
10. RS 485 driver fault
Start-up diagnostics

6 Diagnostic & Troubleshooting
6.1 Diagnostic
There are two different type of diagnostic information:
1. local, by FAULT LED flashing
2. remote, by diagnostic information available from FBP
When the FAULT LED flashes at least one of the following conditions is verified
6.2 Troubleshooting
Depending on the status and behaviour of the LEDs it’s possible to get locally some
information:
#
Symptom
Diagnosis
1. Some or all LEDs still ON after start-up sequence
SW/HW bug
2. - TX LED flashes (very fast) and
No response from the device
- FAULT LED flashes at 2 Hz and
- FBP LED flashes at 2 Hz
3. FAULT LED flashes at 2 Hz
- Previously detected fault and
- no communication with the FBP
Table 6. Troubleshooting
NOTE: the PWR LED is always ON if EP010 is powered.

Please note that NO communication between FBP and EP010 is active if there
is a failure on the relevant serial channel (UART).
Total length of the Modbus cable from EP010 to connected device has to
be less or equal to 1 m.
