I was looking for some help with the problem of data aquisition for a three way valve.
I found some information in the users guide of acad p&id:
However, a component can have multiple acquisition sources. If these sources have identical values or some identical values along with others that are unspecified, a value can be acquired. Only when the sources have conflicting values is the acquisition impossible. A question mark is displayed in place of the acquired value.
For example, a three-way valve has a direct relationship with three different pipe line segments. In such cases, as long as the different sources either have the same spec value (for example: PVC) or the same value in combination with blank values, the valve acquires the value. If the pipe line segments have different specs, a question mark is displayed in the valve Spec field.
Unfortunately there is no siolution for the problem. Is the only way, to manual override the aquisition property?
