765-1205/100-000
The following figure shows the structure of the AoE header area and AoE data area of the
ISDU read service.
(2) AoE Read Response: Response of the ISDU Read Service
The EtherCAT master receives the AoE read response (number (2) in figure "ISDU Read
Process (EtherCAT)").
• If the Result parameter in the AoE data area of the response packet is equal to 0, then
the response of the ISDU read service has been read.
• If the Result parameter in the AoE data area of the response packet is not equal to 0,
then an error has occurred, and the operation was unsuccessful.
AoE Read Response: Structure of the AoE Data Area (in Case of Success: ADS
Return Code Equals 0)
If the Result parameter (offset 0) in the AoE data area of the response packet has the
value 0, then the ISDU read request has been executed, and the user data is located in
the Data parameter (starting at offset 8).
The response has the following structure:
Offset
0
4
8
AoE Read Response: Structure of the AoE Data Area (in Case of Error: ADS Return
Code Not Equal to 0)
If the Result parameter (offset 0) in the AoE data area of the response packet has a value
not equal to 0 (ERR_NOERROR), then the ISDU read request could not be executed.
The Result parameter contains the error number.
