Notes
• DARWIN is a system comprising a number of data-acquisition equipment components. In the
course of system growth, new models, software, various input/output modules and optional
features are added to the family to enhance the systems expandability and flexibility. You can
check the versions of your equipment and software by referring to the style number (Sn) and
release number (Rn) respectively which are shown on the nameplate of the main unit.
When configuring a system, you must confirm that the style number of each component unit and
software meets the following requirements:
1 the style number of each input/output module must be the same as or lower than that of the
main unit or subunit to which the module is connected.
2 the release number of a dedicated software package must be the same or higher than the style
number of the main unit or subunit where the package is installed and where it performs
control.
Any equipment/software not meeting these requirements might have incompatible areas with
your system configuration.
In this manual, equipment of style S8 is explained.
For unsupported functions as classified by the style number, see the next page.
