2.12 High-speed Counters
There are two types of high speed counters provided including Software High Speed Counter
(SHSC) and Hardware High Speed Counter (HHSC). The same Input point (X) can be designated
with only one high speed counter. Double designation on the same input or the same counter will
result in syntax error when executing DCNT instruction.
Applicable Software High Speed Counters:

U: Count up D: Count down A: Phase A input B: Phase B input
Note:
1. SHSC supports max 10kHz input pulse on single point. Max 8 counters are applicable in the
same time.
2. An SS2, SA2, SX2, SE model does not support a two-phase two-input counter (C232 with the
input points X0 and X2).
3. For 2-phase 2-input conuting, (X4, X5) (C233) and (X6, X7) (C234), max 5kHz. (X0,X2) (C232),
max 15kHz.
4. 2-phase 2-input counting supports double and quadruple frequency, which is selected in D1022
as the table shown below.
5. R/F (Rising edge trigger/ Falling edge trigger) can also be specified by special M. OFF = Rising;
ON = Falling.
6. U/D (Count up/Count down) can be specified by special M. OFF = count up; ON = count down.
