The tab shows all slaves that are inserted below a specific master with an assignment to the sync units.
With the EtherCATsync units, multiple slaves are configured into groups and subdivided into smaller units. For each group, the working counter can be monitored for an improved and more exact error detection. As soon as a slave is missing in a sync unit group, the other slaves in the group are also shown as missing. Detection occurs immediately in the next bus cycle because the working counter is checked continuously. With the device diagnostics, the missing group can be remedied as quickly as possible.
Unaffected groups remain operable without any interference.
Sync unit support is defined by the device description of the EtherCAT Master and can be disabled for OEM-specific device descriptions. By default, it is provided with a device description of version 3.5.8.0 and higher.
