5.5 Diagnostics via EtherCAT
5.5.1 Basic information
Availability of diagnostic information via the EtherCAT network
– Note that the diagnostic information shown depends on the settings ( Section 3.2.6)
and the parameterisation ( Section 4.6) of the CPX terminal ( Section 5.1).
– Activate the I/O diagnostics interface to ensure that error messages of the CPX
terminal are automatically displayed in the EtherCAT configuration software,
e.g. Beckhoff TwinCAT.
5.5.2 Diagnostics via SDO access
The higher-order controller can request diagnostic information from the bus node via SDO access. The
corresponding objects can be found in the object directory in section A.2.
5.5.3 Diagnostics via diagnostics history
The 20 most recent diagnostics messages can be called up with the help of the diagnostics object
0x10F3. For every event stored in the device (warning, error, information), an error message referenced
with a code is displayed. Diagnostics messages are decoded via the ESI file and can be read e.g. by the
TwinCAT system manager. The following table shows the structure of the diagnostics object 0x10F3.
The following abbreviations are used:
RO = read only
RW = read/write
RO P = read only (PDO mappable)
