In an integrated environment, engineering data is organized using a plant breakdown
structure (PBS). For example, a PBS for organizing plant data might be plant/area/system/subsystem
or plant/area/unit.
The PBS hierarchy is defined in the SmartPlant schema and is used to create the PBS
hierarchy in SmartPlant Foundation. This hierarchy is communicated to integrated authoring
tools when SmartPlant Foundation publishes the plant breakdown structure and the tools
retrieve it.
Integration Hierarchy Limitations
The integrated environment imposes the following limitations on custom hierarchies,
based on requirements from the authoring tools. This list includes the tool imposing
each restriction, so that customers can factor these limitations into their hierarchy
setup based on their current and future tool usage.
-
The hierarchy must have a minimum of 3 levels. This limitation is imposed by Smart
Instrumentation.
-
The names of hierarchy items cannot be changed once created. This limitation is imposed
by SmartPlant Foundation.
-
The hierarchy scheme cannot be modified after the plant is created. This limitation
is imposed by Smart P&ID and SmartPlant Foundation.
-
If using a unit in the hierarchy, the unit number must be unique. Unit names can be
duplicated across the hierarchy. This limitation is imposed by Smart Instrumentation.
Plant Naming Guidelines
Use the following guidelines when naming your plant, or top-level hierarchy items,
which will be used in an integrated environment. These limitations are imposed by
the authoring tools and the database software. For these guidelines, "plant" is used
as an example of a top-level hierarchy item.
-
Do not use special characters at all in any part of a plant name or plant breakdown
structure such as area or unit. These include .<,>^=+:?|/';{}[]~`!%*()&$@#".
-
A warning message that the characters are invalid is displayed if you use any special
characters.
-
The plant name is case-sensitive and cannot exceed 52 characters if Smart Instrumentation
will be participating in integration.
-
The plant name must be unique within the current domain. This limitation is imposed
by Smart Instrumentation.
-
We recommend that the Smart Instrumentation domain schema name and domain name match
the plant name.
-
We recommend that the plant name be the same name across all authoring tools.
-
You can use digits and spaces within the body of the plant name, for example Plant
1. However, spaces are treated the same as underscores; so, if you name a new plant
with a name that already exists, but use a space or an underscore to differentiate,
an error message will state it is already in existence. For example, Plant 1 and Plant_1
are considered the same.
