7.3 Implementation
Table
The following table identifies the variations, function codes, and qualifiers supported by the
AT Series Communications Module PC Board (
A12
) in both request messages and in
response messages.
For static (non-change-event) objects, requests sent with qualifiers 00, 01, 06, 07, or 08, will
be responded with qualifiers 00 or 01. Static object requests sent with qualifiers 17 or 28 will
be responded with qualifiers 17 or 28. For change-event objects, qualifiers 17 or 28 are
always responded except in the case of object 70 change events which respond with qualifier
1B or 5B.
