This conclusion is calculated according to the formula T_reply [µs] = 2 x (6.0 x 2 3.0 x 2) 6.0 in 6.2.2.

--- Modify "Individual_Event_Response" in 6.3.2 to "Single_Event_Response", the whole text is unified.

--- Modify the note in 9.1 to a clause, because the content described in this note is a definite binding description, which is used to describe the main parts of this chapter

content.

--- Modify the note in 9.3.1 to a clause, because the content described in this note belongs to a definite binding description.

--- Modify the bit 0 of Figure 63 in 9.4.1 from "X" to "0", because in the format of the device status response frame, bit 0 means SP, the position

0 indicates that the device has the capability of device status and process data, set to 1 indicates a special device, and the device shown in Figure 63 is called

The proposed master device, which has the capability of device status and process data, so 0 should be set to "0".

--- Deleted the gateway function (see Chapter 12).

This section also made the following editorial changes.

--- Modified Note 2 in 7.4.2.1 -3 ('1110'B) to -3 (' 1101'B), because the complement of -3 is 1101.
