Extended Diagnostics' tab (EtherCAT Slave Online Functions)

This editor tab is only available for an EtherCAT slave station.

The tab provides diagnostic information on the slave which is currently selected in the tree on the left. Which information is displayed depends on the slave (for instance, the number of ports the slave has).

'Common Error Counter' section

Element	Description
Processing Unit Error	The processing unit error counter is located at register offset 0x030C. The counter logs the number of non-EtherCAT frames (i.e., which are invalid in the EtherCAT segment) the slave has received.
PDI Error	The processing unit error counter is located at register offset 0x030D. The counter logs the number of Process Data Interface errors in the slave. These are physical errors which were detected by the PDI at the EtherCAT bus.
Clear Error Counters	Clicking this button resets all counters displayed.

'Port y Counters' section

Which ports are actually listed depends on the slave. Errors are only counted if the corresponding port is enabled.

y represents the port number.

Element	Description
Invalid Frames, CRC Error	This counter is located at register 0x300 + y*2. The counter logs the number of corrupted frames transmitted via this port (detected due to an invalid CRC).
RX Error	This counter is located at register 0x300 + y*2 + 8 bit. The counter logs the number of RX errors at this port.
Lost Link	This counter is located at register 0x310 + y. The counter logs the number of lost connections at this port.
Forwarded RX Error	This counter is located at register 0x380 + y. The counter logs the number of Forwarded RX errors at this port.
