In the function (FC) block interface, the input parameter ARRAY_A is a one-dimensional
array with variable dimensions.
If the "Enable_Start" operand returns signal state "1", the CPU executes the
LOWER_BOUND instruction. It reads out the variable low limit of the ARRAY #ARRAY_A
from the one-dimensional array. If the instruction executes without errors, it sets operand
"Enable_Out" and sets the "Result" operand to the low limit of the array.
