Loop Unrolling Threshold
Specify minimum array size width for generating for loops
Model Configuration Pane: PLC Code Generation / Optimization
Description
The Loop unrolling threshold parameter specifies the minimum signal or parameter width for which a for loop is generated.
Settings
5 (default)
Specify the array size at which the code generator begins to use a for loop instead of separate assignment statements to assign values to the elements of a signal or parameter array.
When the loops are perfectly nested loops, the code generator uses a for loop if the product of the loop counts for all loops in the perfect loop nest is greater than or equal to this threshold.
Recommended Settings
