Definition of attribute names for each element, functions and scan rates

A Microsoft Excel representation of Table 2 in the measurement configuration file

Constructing the table

The header row of the table must contain columns with the explicit text as follows in order to be valid:

There are four columns in this table:

• [Element Path]

  The path to each element.

• [Attribute Name]

  Each attribute belonging to the leaf element of the path.

  Note: Attribute name field is not effective for hieratical structure assets. Therefore, there is no need to specify an attribute name for those measurement definitions.

• [Function*]

  The function, path (channel), and parameter information for the attribute.

  Note: The "*" sign after the header content means this column is mandatory and cannot be left empty.

• [Scan Rate]

  The scan rate of the measurement in milliseconds.

  Column name	Rules
  [Element Path]	Each entry must be defined in Table 1. All rules for [Element Path] in Table 1 apply.
  [Attribute Name]	Only effective for single attribute measurements Must be unique for the same element. Must be a valid attribute name for PI Asset Framework. Optional: If not configured for single attribute measurements, the connector uses [Function*] entry if [Attribute Name] is left empty.
  [Function*]	The following functions can be defined in Table 2 in the CSV file: cnc_sysinfo cnc_statinfo cnc_alarm cnc_exeprgname cnc_rdmacro cnc_rdprgnum cnc_rdpmcrng cnc_modal cnc_rdaxisdata cnc_rdspmeter cnc_acts cnc_rdsvmeter cnc_actf cnc_absolute cnc_machine cnc_relative cnc_distance cnc_rdseqnum cnc_rdpm_item cnc_rdspeed cnc_ rdopnlsgn1 cnc_ exeprgname2 cnc_gettimer Format: <Function Name>.<Channel>.<Parameter>, such as: cnc_rdmacro.0.#123; cnc_sysinfo.0.mt_type. All function components must be supported by the connector and the CNC machine. Must be unique in the CSV file.
  [Scan Rate]	If defined, value must be between 100 and 10000. The attribute will be created as real-time data. Optional for functions that return a single attribute; the connector will treat the attribute as a static attribute if it is left empty. Required for functions that return hierarchical structures. All dynamic attributes in the hierarchical structure will update at the specified rate. Note that a value for Scan Rate must be specified for: cnc_rdaxisdata cnc_rdsvmeter cnc_rdspmeter
