5.2.8 Task Moves
If a Task_Name is defined the move will become a repetitive task and the data will be updated on a regular basis. The time between updates can be set using
the Scan_Interval parameter. If the Scan_Interval parameter is set the Task_Name parameter must be set. If a Task_Name is declared, but no Scan_Interval is
defined, a default scan interval of 1s is assumed.
5.2.8.1 Special Application: Node Status
The following data array can be configured to capture the status of a Node (Refer also to Section 6.1.1)
Data Arrays
Data_Array_Name , Data_Format , Data_Array_Length , Data_Array_Function
DA_Comm_OK
, Bit , 256 , Node_Status
Target_DA , Bit , 200 , -
Node status bits are only evaluated by the FieldServer when the data is accessed. Since the data is only accessed on update, the data will be neither accessed
nor updated and a move would never occur. This can be circumvented by giving the move a Task_Name and specifying a Scan_Interval.
