DVP-ES3 Series Programming Manual Symbol S 1 ： Counter number S 2 ： Comparative value D ： Comparison result _6 Explanation 1. Use this instruction with high-speed counters with numbers HC200 and above. If the value in the high-speed counter specified by S 1 changes by increasing or decreasing by 1, the DHSCS instruction makes the comparison immediately. When the current value of the high-speed counter is equal to the comparative value specified in S 2 , the device specified by D changes to ON. After that, the device specified by D remains ON even if the comparison result is that the current value and the comparative value are not equal. 2.
If the device specified by D is Y0–Y7 and Y10–Y13, and the value of S 2 is equal to the current value , the comparison result of the high-speed counter is output to the output terminals Y0–Y7 and Y10–Y13. Other Y devices are affected by the scan cycle, but this instruction updates all devices immediately and is not affected by the scan cycle. 3. The D operand can also specify an I interrupt device between 1200–1267. 4. The high-speed counters are divided into software counters and hardware counters. The available high-speed comparators and interrupt device numbers are listed in the following table.
