S 1 should be equal to or smaller than S2 (S1 ≦ S2).2. If D is specified as Y0~Y3 in this instruction, the compare result will immediately output to theexternal outputs Y0~Y3. However, other Y outputs will still be updated till the end of program.Also, M and S devices, not affected by the program scan cycle, will be immediately updated aswell.3. High speed counters include software high speed counters and hardware high speed counters.In addtiion, there are also two types of comparators including software comparators andhardware comparators. For detailed explanations of high speed counters please refer to section2.9 in this manual.4.
