Introduction
There are many tools available to help trace EtherCAT faults. This document describes some more advanced features that can help pinpoint an intermittent or hard to find issue. You will need a good working knowledge of the machine and the basis of EtherCAT networking
Étape 1 - Set Up Advance CRC Checking
- Choose the device network to interrogate and press the Advanced button
- Expand to the Diagnostics-Online View and select the CRC checks 0300-0304 and Link Lost 0310-0312. Click ok to exit
- On the online view, the system now records more detail about the CRC errors or link lost problems.
In the case in the pictures, FB015B has recorded 69 errors on issue 0310 , which is "Link Lost A/B". There are CRC errors on the output of FB016B and the input of FB015B. This tells me that the link between FB016B and FB015B is not reliable. Could be a loose connection on the etherCAT and / or power cable
