Range Comparison Method

Up to 16 comparison ranges (lower and upper limit values) and corresponding output bit patterns can be registered in the comparison table. When the PV of the counter first is within the upper and lower limits of one of the ranges for CTBL(882) execution, the corresponding bit pattern (1 to 16) will be output to A613 or A615.
