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:

1-phase input 2 phase 2 input

C235 C236 C237 C238 C239 C240 C241 C242 C232 C233 C234

U/D M1235 M1236 M1237 M1238 M1239 M1240 M1241 M1242 - - -

U: Count up D: Count down A: Phase A input B: Phase B input

Note:

1. U/D (Count up/Count down) can be specified by special M. OFF = count up; ON = count down.

2. R/F (Rising edge trigger/ Falling edge trigger) can also be specified by special M. OFF =

Rising; ON = Falling.

3. SHSC supports max 10kHz input pulse on single point. Max 8 counters are applicable in the

same time.

4. SS2 model does not support 2-phase 2-input conuting by (X0,X2) (C232).

5. For 2-phase 2-input conuting, (X4, X5) (C233) and (X6, X7) (C234), max 5kHz. (X0,X2)

(C232), max 15kHz.

6. 2-phase 2-input counting supports double and quadruple frequency, which is selected in

D1022 as the table in next page
