Attribute Description When updated

:Config_Node_Descriptor Contents of the Node Descriptor for this device (see sub-clause 1.3.3.4).

The :Config_Node_Descriptor is either created when the application is first loaded or initialized with a commissioning tool prior to when the device begins operations in the network. It is used for service dis-covery to describe node features to external inquiring devices.

:Config_Power_Descriptor Contents of the Power Descriptor for this device (see sub-clause 1.3.3.5).

The :Config_Power_Descriptor is either created when the application is first loaded or initialized with a commissioning tool prior to when the device begins operations in the network. It is used for service dis-covery to describe node power fea-tures to external inquiring devices.

:Config_Simple_Descriptors Contents of the Sim-ple Descriptor(s) for each active endpoint for this device (see sub-clause 1.3.3.6).

The :Config_Simple_Descriptors are created when the application is first loaded and are treated as

“read-only”. The Simple Descriptor are used for service discovery to describe interfacing features to external inquiring devices.

fol-lowing fields:

Channel List – The list of channels to be scanned when using NLME-NETWORK-DISCOVERY.

Protocol Version – Used in NLME-NET- WORK-FORMA-TION and NLME-JOIN (Chapter 2).

Stack Profile – Used in NLME-NET- WORK-FORMA-TION and NLME-JOIN (Chapter 2).

Beacon Order – Used in NLME-NET- WORK-FORMA-TION (Chapter 2).

Superframe Order – Used in NLME- NETORK-FORMA-TION (Chapter 2).

BatteryLifeExten-sion – TRUE or FALSE ( sub-clause 2.3.3) Security Setting – Used in NLME-NET- WORK-FORMA-TION ( sub-clause 2.3.3)

The :Config_Node_Descriptor con-tains a field describing this devices Logical Device Type. That informa-tion plus the specific logic

employed in this devices ZDO per-mits the device application to use the parameters in

:Config_NWK_Mode_and_Params to form or join a network consistent with the applications supported on the device.

:Config_NWK_Scan_Attempts Integer value repre-senting the number of scan attempts to make before the NWK layer decides which ZigBee coordi-nator or router to associate with (see sub-clause 1.5.5.4).a This attribute has default value of 5 and valid values between 1 and 255.

The :Config_NWK_Scan_Attempts is employed within ZDO to call the NLME-NETWORK-DISCOV-ERY.request primitive the indi-cated number of times (for routers and end devices).

:Config_NWK_Time_btwn_Scans Integer value repre-senting the time duration (in seconds) between each NWK discovery attempt described by :Config_NWK_Scan _Attempts (see sub-clause 1.5.5.4).

This attrubue has a default value of 1 (second) and valid values between 1 and 255 (seconds).

The

:Config_NWK_Time_btwn_Scans is employed within ZDO to provide a time duration between the NLME-NETWORK-DISCOVERY.request attempts.

:Config_Complex_Descriptor Contents of the (optional) Complex Descriptor for this device (see sub-clause 1.3.3.7).

The :Config_Complex_Descriptor is either created when the applica-tion is first loaded or initialized with a commissioning tool prior to when the device begins operations in the network. It is used for service dis-covery to describe extended device features for external inquiring devices.

:Config_User_Descriptor Contents of the (optional) User Descriptor for this device (see sub-clause 1.3.3.8).

The :Config_User_Descriptor is either created when the application is first loaded or initialized with a commissioning tool prior to when the device begins operations in the network. It is used for service dis-covery to provide a descriptive character string for this device to external inquiring devices.

:Config_Max_Bind A constant which describes the maxi-mum number of binding entries per-mitted if this device is a ZigBee Coordi-nator or ZigBee Router.

The :Config_Max_Bind is a maxi-mum number of supported Binding Table entries for this device.

:Config_Master_Key Master Key used if security is enabled for this device (see Chapter 3).

The :Config_Master_Key is either present when the application is first loaded or initialized with a commis-sioning tool prior to when the device begins operations in the network. It is used for security operations on the device if security is supported and enabled.

:Config_EndDev_Bind_Timeout Timeout value in seconds employed in End Device Binding (see

sub-clause 1.4.3.2).

The

:Config_EndDev_Bind_Timeout is employed only on ZigBee Coordi-nators and used to determine whether end device bind requests have been received within the time-out window.

value set by the NLME-PERMIT-JOINING.request primitive (see Chap-ter 2).

The default value for

:Config_Permit_Join_Duration is 0x00, however, this value can be established differently according to the needs of the profile.

:Config_NWK_Security_Level Security level of the network (see Chap-ter 2).

This attribute is used only on the trust center and is used to set the level of security on the network.

:Config_NWK_Secure_All_Frames If all network frames should be secured (see Chapter 2).

This attribute is used only on the trust center and is used to deter-mine if network layer security shall be applied to all frames in the net-work.

:Config_NWK_Leave_removeChildr en

Sets the policy as to whether child devices are to be removed if the device is asked to leave the network via NLME-LEAVE (see Chapter 2).

The policy for setting this parame-ter is found in the Stack Profile employed.b

:Config_NWK_BroadcastDeliveryTi me

See Table 132. The value for this configuration attribute is established in the Stack Profile.c

:Config_NWK_TransactionPersiste nceTime

See Table 132. This attribute is man-datory for the ZigBee coordinator and Zig-Bee routers and not used for ZigBee End Devices.

The value for this configuration attribute is established in the Stack Profile.d
