Reading validation rules

Validation rules define thresholds, limits, and other parameters for how IEE validates interval and register data. Each validation rule defines whether to route exceptions immediately to the reading validation queue or to send exceptions through automatic estimation and secondary validation.

IEE includes the following types of validation rules:

• Parameter-based. Parameter-based validation rules use logic built into IEE. You define parameters for the rule but do not need to create any formulas. For example, the high limit check requires you to define the thresholds above which data will Warn or Fail validation. IEE includes parameter-based validation rules for interval channels and register channels. For more information, see Interval validation rules and Register validation rules.

• User-defined. User-defined validation rules allow you to create formulas for customized validation checks. For more information, see User-defined validation rules.
