This option shows you to define a functional requirement for a selected loop number. Functional requirement is the combination of loop function and process function data for a specific loop. For example, for Loop FIC-100, F refers to process function and IC to process function. C can be interpreted as measuring and control. During the early stages of a project, the loop functional requirements are known. However, the functional requirements for the project devices are not known yet. To make cost estimations during the early stages of your project, you need loop functional requirements that contain process data, such as loop number, DN, pipe specifications, and so forth. Later on in your project, you can copy these functional requirements to the real devices.
You can define multiple functional requirements for a specific loop number. Also,
you can generate a specification for a loop that has a functional requirement.
-
Create or edit a loop number.
-
On the Loop Number Properties dialog, select Func. Req.
-
On the New Tag Number dialog, under Tag number type the new tag number name and select OK.
-
On the Select Process Function dialog, select the process function that you need and select OK.
-
On the Tag Number Properties dialog, define the properties of the new tag number as you require.
-
Select OK.
