CDAQMXItemConfig Class
CDAQCongig
CDAQMXItemConfig
This is a setup data class providing functions that access the setting contents using
setup items.
Access using setup items involves the loading from or writing to the fields of the
content. In principle, all contents are processed even they are unused, indefinite, or
illegal. The contents are not checked for validity.
The class supports functions that indicate content fields using strings. If a type is
defined with a constant, it is expressed with the string that indicates the type. If
multiple notations are used such as with the CF status type and reference alarm,
they are delimited with commas.
See the constants for the item name strings.
If it does not exist in the return value of the member function, it is usually the case
that the field does not exist.
Functions are supported that retrieve the string as a floating point value from the
item name and decimal point position.
