The diagnosis of the EB 80 POWERLINK system is defined by the state of the interface LED lights.
Each component in the system relays its state, locally by LED lights, and to the POWERLINK node by software messages.
9.1 POWERLINK NODE DIAGNOSTIC MODE
The diagnosis of the EB 80 POWERLINK system is defined by the state of the interface BS, BE, P1 and P2.
9. DIAGNOSTICS

P1/ P2
link/act
OFF
No connection to POWERLINK
ON
(green)
The device is connected to the network but there is no data exchange
GREEN
The device communicates with the network
(flashing)
BS
OFF
The device is in the INIT state
GREEN
(double flashing)
The device is in the PRE-OPERATIONAL state (2° state)
GREEN
(single flashing)
The device is in the PRE-OPERATIONAL state (1° state)
GREEN
The device is in the OPERATIONAL state
BE
OFF
No error - the device is working properly
ON
(red)
Configuration or communication error, cable disconnected
9.2 EB 80 SYSTEM DIAGNOSTIC MODE – ELECTRICAL CONNECTION
Diagnosis of the EB 80 system - Electrical Connection - is defined by the state of Power, Bus Error and Local Error LED lights.
Diagnostic functions of the EB 80 system relay the state of the system via error codes in hexadecimal or binary format to the controller, in order of
priority. The state byte is interpreted by the controller as an input byte.
The table below shows the correct interpretation of the codes.
