Equipment properties and their use

5.11.1 Introduction

You had the option of statically determining the unit candidates prior to SIMATIC PCS 7 V6.1. This meant that selecting the available units in which a recipe

procedure was to be executed in the recipe editor when creating a recipe. You can retain this procedure with SIMATIC PCS 7 V6.1 or later.

You now have the additional option of employing a new strategy, "Unit selection according to conditions". Specific equipment properties are demanded in the conditions, for example, the size of the unit (capacity of a silo) or the material composition of the silo shell.

Equipment properties are assigned to units in the ES configuration and requested as conditions when creating recipes. When the equipment property matches the defined condition in the recipe, the unit is offered for allocation.

5.11.2 Creating equipment properties

Requirement

• The "Shared declarations" folder is created with the subfolder "Equipment properties" in the project.

Procedure

1. Select the folder "Shared declarations". In the shortcut menu, select Insert new object > Equipment property.

2. Name the equipment property (name and display name).

3. From the drop-down list, select the desired data type and assign it an enumeration or unit of measure. For the "Location" data type, assign the additional types "Source", "Destination" and "Via". You can find information about these types in the documentation for Route Control.

4. Complete your specifications in the dialog and confirm your entries with "OK".

Result

You can now assign this equipment property to your units. If you are working in a multiproject, you can adjust your created equipment properties in the MP with the command Shared declarations > Adjust in Multiproject.

5.11.3 Assigning equipment properties to the units

Requirements

• The equipment properties have been created.

• The Plant view is displayed in the SIMATIC Manager.

Procedure

1. Select the hierarchy folder of the unit to which you want to assign the

equipment properties, right-click and select the shortcut menu command Insert new object > Equipment property.

2. Select die equipment property, right-click and select the shortcut menu command Object properties.

3. Select the desired equipment property in the drop-down list of the name box.

The instance is then given the same name as the original in the shared declarations.

4. In the "Value" box, enter a value for the instance of the equipment property. If your equipment property contains an enumeration, you also have the option of selecting a value for the enumeration used in a drop-down list in the "Value"

box.

5. Complete your specifications in the dialog and confirm your entries with "OK".

Result

The selected units are now assigned with equipment properties and values.

Following the generation of the batch types, these are available for allocation conditions when creating recipes in the recipe editor.

5.11.4 Configuring unit group

If you use several units with identical equipment properties, you can assemble them into unit groups. Prior to SIMATIC PCS 7 V6.1, this group was the unit class.

When you migrate older projects, these groups are given the equipment property

"UnitClass".

Procedure

1. In the Component view of the SIMATIC Manager, create a new "enumeration"

object in the "Enumerations" folder under the shared declarations. Then assign the group a name, for example, Pcell Groups. Insert several "Value" objects with names, for example, Group_A, Group_B, etc.

2. Create an equipment property with an appropriate name, for example, Pcell Group. Assign this process cell group the data type "INT" or "DINT" and select the newly created enumeration from the "Enumeration" drop-down list.

3. Complete your specifications in the dialog and confirm your entries with "OK".

4. Now assign each unit to one of the created unit groups. To do this, select the hierarchy folder of the unit, right-click and select the shortcut menu command Insert new object > Equipment property.

5. Select die equipment property, right-click and select the shortcut menu command Object properties.

6. In the name box, select the newly created equipment property from the drop-down list, in our example "Pcell Group".

7. Select a process group in the "Value" box.

8. Open the configuration dialog "Configure batch process cell ...".

9. After running the "Generate batch types" function, the configured data is made available.

10. If you have configure one or more enumerations as an equipment property, you can set one of them as a group criterion for the recipe editor. Select the

"Pcell" folder and select the desired process cell group for the "Unit group".

Result

You have assembled several units with identical properties in a unit group. When creating the recipe, you use the unit group as a criterion for the unit allocation.

5.11.5 Specifying units using conditions

In the recipe editor, you can use conditions to specify units that match the required equipment properties. When a plant is changed or expanded, the list of available units is adapted automatically without change to the recipe.

Requirement

The Batch Control Center is open.

Procedure

1. Select the menu command Options > Settings > Project settings and activate the check box "Unit selection according to conditions" in the "General"

tab. You have now set this strategy as the default for new recipes or expanded recipe procedures.

2. Open a new recipe in the recipe editor. Open the "Properties of ..." dialog with the menu command Recipe> Header parameter ... and open the "Allocations"

tab.

3. Select the desired recipe assignment from the list and click "Edit". If there is no recipe assignment, first click "New".

4. Click "New" in the dialog that opens. This creates a new, empty condition.

5. Click "Change" to make additional settings in the subsequent wizard.

In the first step, select the desired equipment property and click "Next".

In the second step, select the operator ("available" means that only that it is present, not that a value of the equipment property is evaluated).

In any third step, select or enter the required value of the equipment property.

In the final step, click "Finish".

Using the operators, you can logically associate several conditions with queries of equipment properties.

6. Close the dialog with "OK".

Result

The available units in which the recipe procedure can run are displayed in the

"Allocation" tab. The unit allocation is determined by SIMATIC BATCH from the recipe phases and conditions used and cannot be edited.
