Network port for MS/TP (NwkPortMSTP)

"Network number" indicates the BACnet network number associated with this network.

0

The number is not known or cannot be determined. Default value

0..65534

Value range

"Link speed" indicates the network communication rate as the number of bits per second. A value of 0 indicates an unknown communication rate.

If this property is modified, the property Changes-Pending will be set to true. The new value of Link-Speed-Autonegotiate will be activated when a value of activate is written to the property Command.

"Link speeds" indicates an array of the link speeds supported by this network port.

"Link speed auto-negotiation" specifies the auto negotiation setting of the port.

If this property is modified, the property Changes-Pending will be set to true.
The new value of Link-Speed-Autonegotiate will be activated when a value of activate is written to the property Command.

True

The speed of this network port is automatically determined by the device.

False

The link speed is determined by the value of property "Link speed".

"Max. number of managers" specifies the highest possible address for manager nodes. The same information will also be modeled as property of a network port object.

Range: 1..127

If this property is modified, the property Changes-Pending will be set to true.

The new value of Max-Manager will be activated when a value of activate is written to the property Command.

"Maximum info frames" specifies the maximum number of information frames the node may send before it must pass the token.

If this property is modified, the property Changes-Pending will be set to true.

The new value of Max-Info-Frames will be activated when a value of activate is written to the property Command.

"MAC address" indicates the BACnet MAC address used on this network and willl be provided by the cloud when registering the device.

"Device instance number" indicates the Instance Number of the Object-Identifier of the BA-Device-Object.

If this property is modified, the property Changes-Pending will be set to true. The new value of Instance-Number will be used as object instance number of the Object-Identifier of the BA-Device-Object when a value of activate is written to the property Command.

"Device name" indicates the Object-Name of the BA-Device-Object.

If this property is modified, the property Changes-Pending will be set to true. The new value of Device-Name will be used as Object-Name of the BA-Device-Object when a value of activate is written to the property Command.

"Command" property allows triggering various actions to be performed by the network port object. A new command may only be written if the value of property Command is idle.

Command

Function

idle

Default value. An error will be returned.

activate

The current configuration property settings will be activated.

A new Command activate may only be written if the value of property Command is idle.

The property value remains active until the activation is finished or fails.

If the property Changes-Pending is false, the property Command will be set to idle.

If activation of the settings succeeds, the property Changes-Pending will be set to false and the property Command will be set to idle.

If activation of the settings fails, the property Reliability will be set to ACTIVATE-FAILURE. The property Changes-Pending will remain true, and the property Command will be set to idle.

If the device cannot perform the activation without a reinitialization of the entire device, then it will reinitialize itself when running the command activate.

discard-changes

The modified configuration property settings will be discarded.

A new Command discard-changes may only be written if the value of property Command is idle.

The modified properties will revert to the set of property values that were contained when Changes-Pending was first set to true. The property Changes-Pending will be set to false, and the property Command will be set to idle.

restart-port

The device will be reinitialized to restart and reconnect to the network.

A new Command restart may only be written if the value of property Command is idle.

The property Changes-Pending will be set to false, and the property Command will be set to idle.

"Changes in progress" indicates whether the configuration settings in the network port object map to the current configuration settings.

false

The configuration settings reflect the current port configuration information.

true

The configuration settings have been modified but have not been activated on the port.

"State flag" represents four boolean flags ("Out of service", "Overridden", "Fault", "In-Alarm") that indicate the general status of an object.

'Reliability' indicates whether the property value 'Present value' is reliable. If the 'Present value' is not reliable, the property 'Reliability' indicates the cause of the fault and the bit "Fault" of the state indication is set to 'True'. In a normal case, the property 'Reliability' is set to "No fault".

Property ID: 103

"Object access level" defines the instance-specific object access level. "Object access level" is used for generic filtering and processing an object by a client application.

• "Object access level" is a configuration property which can only be set up offline (ABT, application configuration).
• "Object access level" is evaluated by client applications such as Technical Operator, DB-Import, and APOGEE Point Team mapping.

Access level

Name

Description

7

Basic operation

Access to BACnet objects and properties for a room user e.g. data points visible on a room unit.

6

Standard operation

Access to BACnet objects and properties for standard operation and monitoring (daily business), .e.g. room and plant information on a management station.

5

Extended operation

Access to BACnet objects and properties for extended operation and monitoring such as network and device objects. All I/Os are visible

4

Administrator

Not used by HQ solutions yet.

3

Basic service

Access to BACnet objects and properties used for commissioning, e.g. configuration value extensions, I/O extensions, etc.

2

Extended service

Not used by HQ solutions yet.

1

Internal

Access to all BACnet objects and properties for very specialized actions e.g. during development.

"Object usage" indicates whether the object is used or unused. The "Object usage" property can hide or display respective objects and their functionality in a client. For example, room functionality can be marked for flexible room arrangements as used/unused. An object that is marked as unused behaves as if the object does not exist.

Property ID: 4930

"Description" is a string of printable characters whose content is not restricted.

"Object name" represents a name for the object that is unique internetwork-wide. The minimum length of the string is one character. The set of characters used in the "Object name" are restricted to printable characters.

"Object identifier" is a numeric code that is used to identify the object. It must be unique internetwork-wide.

"Object type " indicates membership in a particular object type class. E.g. "Analog input", "Binary output", "Event enrollment", "Trend log", etc.

"Building automation profile" is an enumeration that indicates a particular type of Siemens proprietary object. Siemens objects are based on standard BACnet objects. For example, Siemens Analog Input, Analog Output, Analog Calculated Value, and Analog Configuration Value are based on standard Analog Input, Analog Output, and Analog Value BACnet objects.

"Profile name" indicates the name of an object profile to which this object conforms. To ensure uniqueness, a profile name must begin with a vendor identifier code followed by a dash. All subsequent characters are administered by the organization registered with that vendor identifier code. The vendor identifier code that prefixes the profile name indicates the organization that publishes and maintains the profile document named by the remainder of the profile name.

A string of printable characters whose content is not restricted.
