You can use the Handheld Programmer or
Direct SOFT to set the proper bits in
V7633.
Since you cannot access the bits
individually, you have to enter a constant
that will result in the appropriate bit being
set. The first two digits of the constant are
used to select the CPU options. The
second two digits are used with the
High-Speed I/O function to select various
options. If you’re using High Speed I/O
functions, make sure you also enter the
appropriate code for the feature selected If
you want the HSIO inputs and outputs to
default to regular I/O point operation, just
enter 60 as the last two digits of the code.
This configures all I/O points to operate
only as standard discrete I/O.
The diagram shows how the upper and
lower bytes of V7633 are used. For
example, if you entered 2060 into V7633,
the powerup-in-run option is selected, and
the discrete filtered inputs are selected.

Since the changes take affect immediately, you may receive an error message. For
example, if you select Power-up in Run Mode and the CPU does not yet contain a
program, an error will occur.
