122 Configuration protection
Section 5: Startup and meter configuration Reference, Installation, and Operations Manual
June 2013 3-9000-743 Rev S
Conventions used for data points reference
This section identifies the groups of data points that must be configured, along with
interrelations and dependencies that should be considered when configuring the meter. This
section assumes that the Mark III meter communication parameters have been configured as
described in Section 5.3. Therefore, in the discussions that follow, the data points are grouped in
the same way they are displayed in Daniel MeterLink screens. Also, the groups of data points are
presented in a sequence that is recommended for configuring a new or unconfigured flow
meter. References to specific data points, or data point labels, are printed in bold, sans serif type.
The following data point labels are examples:
• BaudPortA
• EnablePressureInput
Also in the sections that follow, references to options for each of the data points are printed as
they are displayed in Daniel MeterLink, along with the actual values or the data type (e.g., string,
integer) or units of measurement (e.g., Kelvin, meters) that may be associated with the data
point. The actual values, data type, or units of measurement are printed in parentheses. The
following are example data point options for
InputPressureUnit:
• Gage (FALSE)
• Absolute (TRUE)
In the above example, Gage and Absolute are the data point options displayed in Daniel
MeterLink (in a dropdown list). The actual values associated with the data point are FALSE and
TRUE, respectively, as shown in the parentheses.
5.6.2 Configuration protection
The Mark III meter provides configuration protection which is a means of protecting the
firmware and certain configuration data points from changing. The configuration protection is
enabled/disabled via a CPU Board switch as described in Section 3.5.8. Also see Appendix E.
In general, the data points that are protected by configuration protection fall within these
groups:
• Meter identification
• Units system
• Operational (i.e., transducers control, etc.)
• Meter correction parameters
• Alarm parameters
• AGA8 configuration
• Frequency outputs configuration
• Digital outputs configuration
Data points labels are used extensively in Daniel MeterLink online and printed reports,
such as Edit/Compare Configuration.
