b) When the present value in C249 changes from 99 to 100, the drive contact of C249 will be On immediately. When
the execution arrives at SET Y17, Y17 will still be affected by the scan time and will output after END instruction.

Program Example 3:
1. High speed counter interruption:
a) Operand
D
of DHSCS instruction can designate I0
□
0,
□
= 1 ~ 6, as the timing of interruption when the
counting reaches its target.
b) ES/EX/SS series MPU does not support high speed counter interruption.
c) SA/SX/SC series MPU supports high speed counter interruption. However, when DHSCS instruction
designates an I interruption, the designated high speed counter cannot be used in DHSCS, DHSCR, DHSZ
instructions. Misuse of high speed counter will result in error.
d) For SA/SX/SC series MPU, when the counting reaches the target, the interruption will occur. X0 is the
counter for counting input and the interruption No. is I010 (1 phase 2 inputs and A-B phase counter No. C246
~ C254 can only designate I010). X1 designates I020; X2 designates I030; X3 designates I040; X4
designates I050; X5 designates I060, totaling 6 points.
e) When the present value in C251 changes from 99 to 100 or 101 to 100, the program will jump to I010 and
execute the interruption service subroutine.

2. In SA/SX/SC series MPU, M1059 is “I010 ~ I060 high speed counter interruption forbidden” flag.
3. In EH/EH2/SV series MPU, M1289 ~ M1294 are the respectively for I010 ~ I060 “high speed counter
interruption forbidden flags”, i.e. when M1294 = On, I060 interruption will be forbidden.
