Diagnostic methods
The EL3773 offers two methods of diagnosis:
- Process data
Some diagnostic details are given in the status word of the process data, see Process data. - Diag Messages
Diag Messages can be read at any time from the CoE object 0x10F3.
System Manager Logger Output
Explanation of some typical EL3773 logger messages:
Fig.161: EL3773 logger messages - Parameter written too high, 0x06090031
CoE parameter is too large; the firmware limits the values to be written - Parameter written too low, 0x06090032
CoE parameter is too small; the firmware limits the values to be written - Data can not be transferred or stored to the application because of the present device state, 0x08000022
No supply voltage, terminal partly out of service
Diag Messages
Diag Messages designates a system for the transmission of messages from the EtherCAT Slave to the EtherCAT Master/TwinCAT. The messages are stored by the device in its own CoE under 0x10F3 and can be read by the application or the System Manager. An error message referenced via a code is output for each event stored in the device (warning, error, status change).
See the Diag Messages notes regarding this.
