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

Data points labels are used extensively in Daniel MeterLink online and printed reports, such as Edit/Compare Configuration.

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.

5.6.2Configuration 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
