Service Data Object (SDO)
E3NW-ECT EtherCAT Sensor Communication Units support the SDO communications.
The EtherCAT Master Unit is able to make parameter settings and monitor status by reading and writing
data from and to entries in object dictionaries via the SDO communications.
The table below shows abort codes of SDO communications errors.
The following table gives the abort codes for when sending commands to a Sensor Amplifier Unit fails.
