Parameters

Parameter descriptions and values

Values like "True/False" must be avoided. Rephrase the parameter description if necessary. For example, instead of defining a parameter with description "Manual Mode" and possible values 'True" and "False", it is considered better practice to use the description "Switch Mode" and values "Automatic" and "Manual".

Unit of measure

If applicable, a unit of measure must be provided. See Units.

Value range

If applicable, a value range must be provided for displayed parameters (read and write). See Range.

Date and time values

Parameters used to hold a time, date, or datetime value should be implemented using the "date", "time", or "datetime" option.

See also Options for measurement type number.

Exceptional states

In case a device can return exceptional states (e.g. "N/A", "Unknown", etc.), these should be implemented as Exception or Other and have the disabled state.

Tooltips

All displayed parameters must have a meaningful smart tag (tooltip).

Octet values

Octet values should be implemented as bit rate.

Error Counter values

Error counters should be made available as a rate value.
