Indicates the start of a programming sequence.
|ECU ref in is the task reference which links to the selected ECU. This reference is originally returned from MC ECU Open.vi or MC ECU Select.vi, and then wired through subsequent VIs.|
|Error in is a cluster which describes error conditions occurring before the VI executes. If an error has already occurred, the VI returns the value of the error in cluster to error out.
|ECU ref out is the same as ECU ref in. Wire the task reference to subsequent VIs for this task.|
|Error out describes error conditions. If the Error in cluster indicated an error, the Error out cluster contains the same information. Otherwise, Error out describes the error status of this VI.
If you are using the XCP protocol, MC Program Start.vi implements the XCP command PROGRAM_START. This optional command indicates the beginning of a programming sequence into a non-volatile memory area. If the slave device is not in a state which permits programming, an error is returned. The memory programming commands The end of a non-volatile memory programming sequence is indicated by using the MC Program Start.vi function.
For further information on how to use program ECU memory and to use the MC Program Start.vi command refer to the ASAM XCP Part 2 Protocol Layer Specification.
