■Detection conditions in pulse input modes
The following table shows the detection conditions in each pulse input mode.
*1 The numbers of Detection condition indicate the following parameters.
1: "A: Rise"
2: "A: Fall"
3: "A: Low"
4: "A: High"
5: "B: Rise"
6: "B: Fall"
7: "B: Low"
8: "B: High"
9: "A: Rise+B: Low"
10: "A: Rise+B: High"
11: "A: Fall+B: Low"
12: "A: Fall+B: High"
13: "A: Low+B: Rise"
14: "A: High+B: Rise"
15: "A: Low+B: Fall"
16: "A: High+B: Fall"
■Links of "Pulse Input Mode"
Link the Output terminal where "Pulse Input Mode" is set "UP count" to the "UP" terminal of a counter timer block. Link the
Output terminal where "Pulse Input Mode" is set "Down count" to the "DOWN" terminal of a counter timer block.
Otherwise, values are not correctly counted.
