Operating instructions

5.7 Node Object

5.7.1 Node Object

These variables are used for controlling all functional blocks via the com-

missioning tool.

5.7.2 Object Request

Variable name: SNVT type: Supported functions: Description:

nviRequest SNVT_obj_request RQ_Normal Returns the specified functional block to normal operation.

RQ_Update_Status Requests the status of the specified functional block.

RQ_Report_Mask

Requests a status mask reporting the status bits that are supported

by the specified functional block.

RQ_Disabled

Requests the specified functional block to change to the disabled

state. In the disabled state, output network variables belonging to

the functional block are not propagated within the network.

RQ_Enable

Requests the specified functional block to change to the enabled

state. In the enabled state, output network variables belonging to

the functional block are propagated within the network as defined

by the functional block.

5.7.3 Object Response

Variable name: SNVT type: Description:

nvoStatus SNVT_object_status

This output network variable reports the status for any functional block on a device. It is also used to report

the status of the entire device and all functional blocks on the device.

5.7.4 Max. Send Time (Heartbeat)

Variable

name:

SNVT

type:

Default value: Min value: Max value:

nciMaxStsSendT SNVT_elapsed_tm 00:0:0:0 00:0:0:0 017:59:59:999

This variable configures a timer to send the nvoStatus object but only if bound to an input variable.

Maximum is '0 17:59:59:999' (0 days, 17 hours, 59 minutes, 59 seconds and 999 milliseconds).

Setting the timer to '0 0:0:0:0' disables it.

Network timer functions monitor node presence and control behaviour in the event of network problems occurring.
