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
