BACnet Property | Short Name | BACnet Description | Notes |
|---|---|---|---|
object-type | ObjTyp | Object type | 264 (Network-Port) |
profile-name | PrfNam | Profile name | 7-054-SBCv15.04 |
Prototype | BAObjTyp | Building automation profile | 54: (MSTP-Network-Port) |
MAC-Address | MACAddr | BACnet MAC address | A writable proprietary property that indicates the port's BACnet MAC address. For MSTP networks, MAC-Address consists of a single octet. The supported value range for MAC-Address is 0-127. |
Link-Speed | LnkSpd | Link speed | A proprietary property that specifies the network communication rate in bits per second. This property is writeable if Link-Speed-Autonegotiate is false and read-only if Link-Speed-Autonegotiate is true. |
Link-Speeds | LnkSpds | Link speeds | A read-only proprietary property that indicates the port's range of values for Link-Speed. The user selects one of these as the Link-Speed for the port. |
Link-Speed-Autonegotiate | LnkSpdAuto | Link speed auto-negotiation | A writable proprietary property that specifies whether the device should attempt to automatically determine the network's link speed or whether the device should use the configured link speed (Link-Speed). |
max-master | MaxMstr | Maximum number of masters | A writable standard BACnet property that specifies the highest BACnet MAC address allowed for MSTP masters on the network. The value range for max-master is 0-127. |
max-info-frames | MaxIfrms | Maximum info frames | A writable standard BACnet property that specifies maximum number of information frames that the device may send on this port before it passes the token. The value range is 1-255. |
Segmentation-Window-Size | SegmWinSize | Segmentation window size | A read-only property set to 1 for MSTP ports. |
Network-Timing | TiModMstp | MS/TP timing mode | A writable proprietary enumerated property that specifies whether the device shall use the standard set of MSTP timing parameters or whether the device shall allow MSTP timing parameters to be customized. |
Reply-Timeout | TioutRply | Reply timeout | A proprietary property that specifies the minimum time, in milliseconds, that a node shall wait for a reply after sending a MSTP Data-Expecting-Reply frame before sending another frame. This property is writeable if Network-Timing is custom, and read-only if Network-Timing is standard. |
Token-Timeout | TioutTkn | Token timeout | A proprietary property that specifies the minimum time, in milliseconds, that a node must wait for a remote node to begin using a token or replying to a poll-for-master frame. If Token-Timeout elapses and the line is still idle, a MSTP token-retry or MSTP poll-for-master is initiated. |
Turnaround-Time | TiTurnard | Turnaround time | A proprietary property that specifies the minimum time, in milliseconds, that a node must wait for a remote node to begin using a token or replying to a poll-for-master frame. If Token-Timeout elapses and the line is still idle, a MSTP token-retry or MSTP poll-for-master is initiated. |
