End Code Examples
The following examples show the end code when a command did not end normally.
Example 1: Illegal Sub-address, No SID, and No Command Text
• If there is an illegal sub-address, and no SID or command text, the response end code will be
16 (sub-address error). (If the sub-address is received, the response end code is 16 because
a sub-address error has a higher error detection priority than a format error.)
Command
Response

Example 2: No Command Text
• If there is no command text, the response end code will be 14 (format error).
