Recall that V7633 is the HSIO Mode Select register. Refer to the diagram below. Use
BCD 60 in the lower byte to select High-Speed Counter Mode. Use BCD 00 or 20 in
the upper byte as required. Combine the two bytes into a data word “xx60”, for writing
to V7633.

Choose the most convenient method of programming V7633 from the following:
S
Include load and out instructions in your ladder program
S
Direct SOFT’s memory editor
S
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 to this.
The configurable discrete input options for Discrete Filtered Inputs Mode are listed
in the table below. The filter time constant (delay) is programmable from 10 to 99 mS.
The code for this selection occupies the upper byte of the configuration register in
BCD. We combine this number with the required “06” in the lower byte to get “xx06”,
where xx = 10 to 99. Input X0, X1, X2, and X3 can only be filtered inputs. Each input
has its own configuration register and filter time constant.
