8.2.1.3 Abort SDO Transfer Protocol
In some conditions, the SDO client or SDO server will terminate the SDO transmission.
For example, the value of entries that users want to modify does not exist or is read-only,
even users wouldn’t continue the uncompleted SDO protocol under some special
situations. When these conditions occur, both the client and the server can be activated
to send the Abort SDO Transfer message. The Abort SDO Transfer protocol is shown
below.
cs
: command specified
4: abort transfer request
x
: not used, always 0
m
: multiplexer
It represents index and sub-index of the SDO
d
: contains a 4-
byte “Abort Code” about the reason for the abort.
