Example
For example, slave station 3 reads data from and writes data to the object whose index is
0x1801 and subindex is 03. (The object whose index is 0x1801 and subindex is 03 indicates
the disabled time of PDO2 Tx. For more information, see Appendix A.)
Write operation example: To modify the disabled time of PDO2 Tx to 1000 ms, the master
station transmits the following write operation command.

After receiving the command transmitted by the master station, the slave station transmits the
