The response to the read request, i.e. the read response, includes confirmation that writing was

Observe data format
During reading and writing, observe the data size and the format of the corresponding SDO param-
eters. We recommend reading the SDO data first, then interpret them and use the read data format
also for writing the CoE data (perhaps swap High/Low BYTE/WORD).
Start-up parameters overwrite COE data
CoE data are typically not stored in the EtherCAT device. Make sure that the CoE data are overwrit-
ten again by the Start-up parameters (GSDML) when starting the EP9300-0022.
