Dialogs are ConditionTypesused by a Serverto request user input. They are typically used when a Serverhas entered some state that requires intervention by a Client. For example a Servermonitoring a paper machine indicates that a roll of paper has been wound and is ready for inspection. The Serverwould activate a Dialog Conditionindicating to the user that an inspection is required. Once the inspection has taken place the user responds by informing the Serverof an accepted or unaccepted inspection allowing the process to continue.
