A.2 Info Tables and Settings Descriptions
The CR6 has several places where system information and settings are stored or
changed:
• Status table — an automatically created data table. In general, status
fields should not be expected to give an instantaneous update of the value
being read. In most cases the values give a reasonable snapshot of the
status of the system. For most applications, there is a way to get an
instantaneous value directly with a CRBASIC instruction.
•
Settings — the CR6 has over 200 settings. Most of these are best
accessed using Device Configuration Utility , which provides more
information about their use.
•
DataTableInfo table — a data table that is automatically created when a
program produces other data tables
•
CPIInfo
table — a data table that is automatically created when a
program includes CPI instructions.
In many cases, the Info Tables and Settings keyword can be used to pull that field
into a running CRBasic program. See
Info Tables and Settings — Setup Tools
(p.
152).
Two data types are identified as being associated with Info Tables and Settings.
These are Numeric and String. For most applications, the CR6 operating system
will handle the nuances of Numerics, which can end up one of several CRBasic
data types.

auto (background) calibration. A separate 12 bit A-to-D converter makes this
measurement with less settling time than the CRBasic
