Note:
1.
The max frequency of the 1-phase input counters X0 (C243) and X2(C244) is 100kHz on
ES2/EX2/SA2/SX2 model and 20kHz on SS2 model.
2.
The max frequency of the 1-phase 2-input counters (X0, X1)(C245, C246) and (X2, X3)(C249,
C250) is 100kHz on ES2/EX2/SA2/SX2 model and 20kHz on SS2 model.
3.
The max frequency of the 1-phase 2-input counters (X0, X1)(C247, C248) is 10kHz on
ES2/EX2/SS2/SX2 model and 100kHz on 32ES211T and SA2 model..
4.
The max frequency of the 2-phase 2-input counter (X0, X1)(C251, C252) is 5kHz on ES2/EX2
model, 10kHz on SS2/SX2 model and 50kHz on 32ES211T and SA2 model.
5.
The max frequency of the 2-phase 2-input counter (X2, X3)(C253, C254) is 5kHz on
ES2/EX2/SA2 model, 10 kHz on SS2/SX2 model and 50kHz on 32ES211T.
6.
2-phase 2-input counting supports double and 4 times frequency, which is selected in D1022
as the table in next page. Please refer to the below table for detailed counting wave form.
