Plant Hierarchy configuration

The Plant Hierarchy (PH) maps the exact structure of your plant, for example, by dividing it into units and functions. The PH has the structure of a tree (as in a family tree). Each item in the PH branches into several sub items. The PH enables a variety of settings:

• Number of levels hierarchical: the more complex the plant, the greater the number of hierarchical levels. This number should reflect the logical structure of the plant. For example, levels may reflect:

Level 1 – Plant

Level 2 – Unit: Buffer Tanks, Material Tanks and Reactors

Level 3 – Function: B410, B420, M-General, M110, M120, M130, R-General, R310 and R320

Level 4 – Device: CFCs in the system are generally included at this level. Ex: V112 (valve) and P113 (motor).

• Determination of hierarchical levels that influence the name of the plant ID – identification of the object in the plant (HID): the PCS 7 project contains many HID instances: generated messages and tag names contain the HID to allow the operator to easily recognize a plant unit associated with a message or tag.

It serves to determine which levels of plant hierarchy that will form the tag (what will appear in the WinCC supervisory). Tag is the identification of an object in the system. You can select all PH levels and form a large and detailed tag name or only select some levels in the tag formation and generate a smaller tag.

Reactor Example:

1 - Selecting all PH levels in the tag formation would look like this:

Plant/Material Tanks/M110/V112... – for valve V112.

2 – Removing Level 1 (Plant) from the tag formation would look like this:

Material Tanks/M110/V112...

3 – Removing levels 1 and 2 from the tag formation will look like this::

M110/V112...

The levels are selected in the Included in HID option in the Customize Plant Hierarchy window (see below).

The tag is formed by the composition of PH Level + Chart name + Block name + I/O name

M110\V112\Valve.Ctrl#Value

PH Level = M110 – In this example, only Level 3 was included in HID. If Levels 1 and 2 were also selected to form the HID, PH Level would be Plant\Material Tanks\M110.

Chart name = V112 – It is the name of the CFC that houses the tag.

Block name = Valve – Is the name given to the programming block (type VlvL, in the example).

I/O name = Ctrl#Value – I/O parameter of programming block.

• Derivation of the hierarchy of screens from PH: process screens are grouped into one hierarchy. This allows you to navigate from an overview screen to a more specific level screen. Subordinate screens represent a portion of the overview screen in greater detail. The hierarchy of process screens (picture hierarchy) corresponds to how the process screens are stored in the plant hierarchy.

Note: this item will be more detailed later in the course.

• Customize PH

• options\plant hierarchy\settings – set number of hierarchical levels = 4;

• maximum number of characters = 10 (important for tag composition in OS);

- OS Area = 2 define until the hierarchical level will represent an area in the OS;

Note: this item will be more detailed later in the course.

•Included in HID = 3 – levels that will form the plant ID in the OS.
