5.2.10.1 Conditional Moves: Example 1
In this example, the user needs to move the data from one of two source locations based on the status of bit 1 or 2 of the conditional Data Array. If bit 1 is
high, then the data from Source_1 will be moved. If bit 2 is high, the Data from Source_2 will be moved. The kernel checks the condition of the bits every
second for a change in status.
Moves
Source_Data_Array , Source_Offset , Target_Data_Array , Target_Offset , Length , Conditional_Data_Array , Conditional_Offset , Task_Name , Scan_Interval
Source_1
, 0 , Target , 00 , 1 , Status , 1 , a , 1
Source_2 , 0 , Target , 01 , 1 , Status , 1 , b , 1
5.2.10.2 Conditional MovesExample 2
In this example, the data from DA_GV_01 will be moved to Gas_Snapshot only when DA_GP_PW_01 or DA_GL_PA_01 is updated on offset 192. In this
example all of the Data Arrays are bits, but analog data types will work as well.
Moves
Source_Data_Array , Source_Offset , Target_Data_Array , Target_Offset , Length , Conditional_Data_Array , Conditional_Offset , Task_Name , Scan_Interval
DA_GV_01 , 192 , Gas_Snapshot , 00 , 1 , DA_GL_PW_01 , 192 , a , 1
DA_GV_01 , 192 , Gas_Snapshot , 01 , 1 , DA_GL_PA_01 , 192 , b , 1
The Conditional Move that executed last becomes the Responsible Move by which data validity is determined, and through which write operations are routed.
If none of the Conditional Moves targeting a specific location have executed, the Conditional Move defined last acts as the Responsible Move.
