Example for Range Comparison for 1 to 32 Ranges (CJ2M Only)
When CIO 0.00 turns ON in the following programming example, CTBL(882) registers a range comparison
table using upper and lower limits for high-speed counter 0 and starts comparison. When the PV of the
high-speed counter leaves the upper/lower limits for range 1, interrupt task 0 is executed. When the PV
leaves the upper/lower limits for range 2, interrupt task 5 is executed.
High-speed counter PV
Upper limit value 2: 2,100 decimal
Lower limit value 2: 1900 decimal
Upper limit value 1: 1,050 decimal
Lower limit value 1: 950 decimal
