An output submodule also has a 2-byte input data (see Table 4-4). This 16-bit integer is the
sequence number of the last output data packet that was transmitted. To confirm that the
last data written to the output data area has been transmitted, compare the sequence
number of the transmitted output data with the input data of that submodule. If they are the
same, the data has been transmitted successfully.
