A piece of response data is four bytes. Byte4 is the LSB, and Byte7 is the MSB. When a
write command is responded, the response data is the data to be modified; and when a
read command is responded, the response data is the data to be read.
An error code is two bytes. Byte2 is the LSB, and Byte3 is the MSB. Error codes are valid
only when the response code is 3. An error code indicates the reason why it fails to
respond to PDO2 Rx.

A reading or writing error occurs. Table 7-16 describes the error codes.
Table 7-16 describes the definitions of the error codes.
Table 7-16 Error code
-
The operation corresponding to the request code is not allowed
to be executed. The possible causes are as follows:
• The function code is applicable only on new devices and is
not implemented on this device.
• The slave station is in the faulty state when processing this
request.
For a slave device, the data address in the request of the master
station is not allowed. In particular, the combination of the
register address and the number of the to-be-transmitted bytes
is invalid.
The received data domain contains a value that is not allowed.
The value indicates the error of the remaining structure in the
combined request.
