Explanation
1. This instruction gets the linear slope, which has an absolute relationship with the scan time. Therefore it is
suggested that you set a fixed scan time or write this instruction in a timer interrupt task.
2. You write the initial value and final value of the ramp signal into S
ON, D increases from the setting value in S
When the value in D is equal to that in S
then SM687 is ON.
3. When the conditional contact is not enabled, the value in D, and D+1 are both 0, and SM687 is OFF.
4. When using on-line editing, Reset the conditional contact to initialize the instruction.
5. Refer to the ISPSoft User Manual for more information on setting a fixed scan time.
6. The value of n must be between 1–32767. When n is out of range, this instruction is not executed.
