Hello, on my ctrlX x3 I'm looking into available data useful for network diagnostics from the etherCAT master app. And I have some questions about the statistics.
1. Where does the CtrlX Core get thoses numbers from? Does the control provide it itself or read it from the
2. For the slave statistic counters there's an input parameter apparently, like in some other nodes as well. But what exactly am I supposed to w
3. In the fielbus status there's a parameter for the master status indicating a number that sometimes
Also in topology status, the state sometimes go pending for a second when a change occurs but always remain "valid" no matter the changes in the topology or if a slave is down for example. I don't understand it.
However in the "ethercat status" window of the ethercat master app. I can correctly see when something is wrong with the topology. But I plan to get those informations with the REST API. That's why those discrepancies bother me a bit.
I haven't seen anything about it in the ethercat master app documentation. Does anyone knows more about it or redirect me to some helpful documentation ?
- Slave statistics are read out of the slaves EtherCat chip and represented in the data layer. See some more description of the function/interpretation by clicking the link in the slave statistics page:
ctrlX OS - web UI - EtherCat slave statistics
- When using version 2.6 of the system you will get an example when opening an data layer address including an object:
ctrlX OS - data layer viewer - access EtherCat slave telegram error counter.png
Please always check the data type mentioned in the metadata of a node. There in generell you can see which data is needed.- fieldbuses/ethercat/master/instances/ethercatmaster/admin/fieldbus_statistic/slave/counters:
e.g. {"request": {"addressType": "fixedphysical", "address": 1001}} - fieldbuses/ethercat/master/instances/ethercatmaster/admin/fieldbus_statistic/slave/reset:
an empty PUT is needed

I hope I could make your points clear. If there are further questions feel free to add them here below.
