BACnet MS/TP Subordinate Configuration: Auto-Configure Mode (Default)
While in Auto-Configure Mode no fields under the Data Groups can be edited. Auto-Configure Mode
looks at the other protocol and then configures the Data Groups below to match. BACnet MS/TP points
will be defined after the other protocol is configured.
Within the BACnet MS/TP Subordinate, the data will automatically be configured according to the
following rules:
1) Any 8 Bit Signed/Unsigned, 16 Bit Signed/Unsigned, 32 Bit Signed/Unsigned, 64 Bit
Signed/Unsigned, 32 Bit Float, and 64 Bit Float data will be mapped as Analog Objects.
2) Any Coils or 1/8/16/32 Bit Binary Packs will be mapped as Binary Objects.
3) Any String Data Types will be mapped as CharacterString Value Objects.
4) The input or output object direction depends on whether it is configured as a read or write on
the other protocol.
5) If the other protocol exceeds the number of analog, binary or CharacterString value objects the
BACnet MS/TP Subordinate supports (see limits on webpage), then nothing will be mapped. You
will see the # of Objects column remain at 0 and the main page will display the following error:
a. To fix this error, simply decrease the amount of data you configured on the other protocol
so that the max number of BACnet objects are not exceeded or call customer support to
increase the limits.
