Use the larger number for addresses beyond 2048 words in the controller’s data table.
i = execution time of each instruction (e.g., ADD, SUB, etc.) used within the FAL or the FSC expression
E = number of elements acted on per scan
B = number of bits acted on per scan
Wi = number of words used by the instruction (e.g., ADD, SUB, etc.) within the FAL or FSC expression
FAL or FSC instructions are calculated with short direct addressing
