7.1.2. Pulse Catch
The input contacts (IX0.0.0 ~ IX0.0.7) are embedded in GM7U series’ main unit. Using this contact point, short pulse signals
like
10 ㎲
can be taken which can not be executed by general digital input.
1) Usage
When narrow width of pulse signal is input, a trouble occurs which can not be detected by general digital input, so the
operation does not perform as user's intention. But in this case through pulse catch function even narrow interval of pulse
signal as 10
㎲
can be detected.
2) Minimum input pulse width
•
IX0.0.0 ~ IX0.0.1: 10
㎲
•
IX0.0.2 ~ IX0.0.7: 50
㎲
3) Operation

Step
Description
Scan1
CPU senses input when pulse signal, min. 10
㎲
, is input, then saves the status.
Scan2
Turn On the input image data area.
Scan3
Turn Off the input imaged data area.
4) Using method
(1)
Click the basic parameter on the project window of GMWIN
(2)
Select no. to use for pulse catch input in the basic parameter window.
For details about GMWIN, refers to the corresponding manuals.
