When to use Pulse Catch Mode
Use the pulse catch mode for applications where the input (e.g. X0) can not be used in the user
program because the pulse width is very narrow. Use SP100 instead of X0. The SP100 contact
stays on through the next scan, as shown above. Even if X0 is on for more than one scan,
SP100 is still on for only one scan.
The status relay for X0 is SP100. The other status relays are shown in the table below.
Setup for Mode 50
Recall that V7633 is the HSIO Mode Select register. Refer to the diagram below. Use BCD
50 in the lower byte of V7633 to select the High-Speed Counter Mode.
Choose the most convenient method of programming V7633 from the following:
• Include load and out instructions in your ladder program
• DirectSOFT’s memory editor
• Use the Handheld Programmer D2–HPP
We recommend using the first method above so that the HSIO setup becomes an integral
part of your application program. An example program later in this section shows how to do
this.
