1               General Information

Using the rule-based design, you can specify rules for working in P&I diagrams and logic diagrams.

You can define rules that are to be taken into account for item combinations on editing sheets. If the defined rules are not met, you can specify the severity level with which the conflict is to be stored. On the sheet, the conflict list is displayed in which the conflicts are described in further detail. You can navigate between the conflict list and the affected objects on the opened sheet.

In case of an error, the conflict is graphically marked with a warning triangle .

In the rules, you can define the following actions:

·            Consistency check

Comparison of the attribute values of

·            Pipelines and objects of an item group or

·            Items of two item groups.

With these actions, you can, for instance, check whether the attribute value of the attribute Nominal Size in a pipeline matches the value of the valves placed into the pipeline as inline devices. If this is not the case, a conflict is displayed in the sheet and in the conflict list.

·            Passing on attribute values from one item to another if the specified conditions are met. This, for instance, enables you to pass on the pipe class of a pipeline to all inline devices.

Prerequisites

You can only use the functionality of this assistant on sheets of the following Smart Diagram Types:

·            P&I Diagram

·            Logic Diagram.
