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.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
