10.2 [SETUP], [SYSTEM]
[Setup] , [System] is a pop-up window used to select the Hardware Definitions to include in the System
Configuration that COMPASS uses when in a run mode. The window is organized by the specific data
acquisition and control functions that COMPASS may use in its various run modes. A hardware
component for each function is selected from a drop down list. With the exception of molbox specific
features, the Hardware Definitions available on the drop down lists are created using
[Setup ] , [Hardware]
(see Section 10.3). molbox features such as the MFC control option and the ability to read pressure and
temperature become available in the appropriate lists when a molbox is selected as the flow reference.
The <System Configuration> screen’s Hardware Definition selection categories as well as instructions
on how to use them are covered in Table 34.
If a molbox is selected as the <Flow Reference> , “Reference molbox” will be an option in all analog power
and measurement lists. If the molbox does not include the MFC control option, do not select
“Reference molbox” from any of these lists. COMPASS will generate an error during run mode
initialization if “Reference molbox” is selected for an electrical function but the molbox does not have
the MFC control option. Only molbox1 can have an onboard MFC control option.
