Function Description
The L9_BLKM block move procedure copies the entire contents of a source table to a destination table in 1 scan.
NOTE: The L9_BLKM procedure will not write to and change the state of any BOOL that has been forced in the Control Expert Animation Table.
Both the source and destination matrices consist of 16-bit sequences of outputs located in %M or %MW memory, depending on the respective procedure. The LENGTH value determines the number of 16-bit sequences included in the block move operation. The SOURCE parameter defines the location of the source table. The DEST parameter defines the location of the destination table.
The block move operation begins when the input to the ENABLE pin is turned ON. L9_BLKM can activate a single output. The OUT output turns ON upon the successful completion of the operation.
