Shared Declarations

If you have created your multiproject with the PCS 7 wizards, the master data library already contains a "Shared Declarations" folder. You can then use this to store shared declarations that can be used by various applications. You can explicitly create the "Shared Declarations" folder if it does not yet exist.

The "Shared Declarations" folder contains the following subfolders:

• Enumerations

• Units

• Equipment properties

You can define the following elements as shared declarations:

• Enumerations

You can use enumerations to define textual representatives for the parameter values of the block or chart I/Os with data types "BOOL," "BYTE," "INT," "DINT," "WORD," and "DWORD". A suitable text is assigned to each value of an enumeration and this is displayed at the I/O. Several values can be assigned to each enumeration.

• Units

The unit of measure (for example, mbar, l/h, kg) is text with a maximum of 16 characters. It can be entered during the parameter and interconnection descriptions of block or chart I/Os. It is used for example, in process pictures when visualizing the values of the block I/Os. All the units of measure included in the CFC basic set are available as defaults.

• Equipment properties

Equipment properties are parameters of a unit, such as shell material, volumes etc. The type of equipment property is defined as a "shared declaration". Instances of this type are used in SIMATIC BATCH and its attributes are individually adapted.

Crushing Soy Project

• Insert Shared Declarations for the Factory_Prj project. Select project, right-click and select Insert New Object > Shared Declarations.

Master Data Library

When creating CFC charts, you should work with the master data library. DO NOT copy any blocks and process tag types directly from PCS 7 standard library to your project's CFC chart. Create the blocks and process tag types in the master data library and copy them from that library to the CFCs charts.

Below, the master data library Training_Lib (blue book) contains in the Blocks folder several FBs from the APL v8.1 library (Component View image).

Below are the Process tag types valves, motors, PIDs, etc.) from the APL v8.1 library: Motor_Lean, PIDControl_Lean and Valve_Lean.

Note: Process tag type will be studied in detail later in the course.

What are the advantages of the master data library?

The use of the master data library ensures that the same block version is used in the project, avoiding confusion. This is especially important if more than one engineer is working on a multiproject.

The use of the master data library also provides another convenient PCS 7 function: hide libraries. This function allows you to hide all libraries except the master data library.

The master data library is archived automatically when multiproject backup.

How to store objects in the Master Data Library

Changes in the blocks

You can change the block properties on the master data library. For example, you can tailor specific messages to the requirements of your project. Each instance of the block you created in CFCs will have its properties changed automatically. With this, you have to change the block only in the master data library and not repeatedly for each created instance of the block.

Modifications of a block intentionally to a specific CFC are made directly in the block instance in that CFC. This includes, for example, input and output parameters, such as setpoints and limit values.

Master Data Library and process tag types

You can also store process tag types provided by PCS 7 in the master data library. All blocks included in the process tag type are automatically included in the Blocks folder of the master data library.

Crushing Soy Project

• Insert a Master Data Library Factory_Lib to the Factory_MP multiproject. In SIMATIC Manager, select File > New... menu item.

• Select Libraries tab.

• Insert Name = Factory_Lib. Type = Library. Choose storage location (default C:\Programs Files (x86)\SIEMENS\STEP7\s7libs). Select Add to current multiproject (Factory_MP) to include the library in the Factory_MP multiproject.

• Close the Factory_Lib library window and work within the Factory_MP multiproject.

• In Component View, enter S7 Program for Factory_Lib. Right-click on the Factory_Lib object and select Insert New Object > S7 Program menu item.

• Insert the Charts folder into the S7 Program of Factory_Lib. Right-click on the S7 Program object and select Insert New Object > Chart Folder menu item.

• Set Factory_Lib library as Master Data Library. When including the library in the multiproject, it is inserted as a common library. To make it the Master Data Library for the multi-project, right-click on the Factory_Lib library and select Multiproject > Define as Master Data Library menu item.

• The color of the book icon changes from green to blue, indicating the Master Data Library.

• Select Plant View. Add Shared Declarations folder to Master Data Library. Right-click on the Factory_Lib object and select Insert New Object > Shared Declarations menu item.

PC Station configuration

• The computer or virtual machine must have changed its name to ES, if this has not been done before installing SIMATIC PCS 7 (guidance given in the installation). Open the Control Panel - System and Security - System. Click Change settings and change the computer name to ES. Restart the computer or the virtual machine after the change.

• Change fixed IP from computer or machine to 192.168.0.2 (Mask 255.255.255.0).

• Add Simatic PC Station to Factory_Prj multiproject. Right-click on Factory_Prj object and select Insert New Object > SIMATIC PC Station.

• Rename the PC Station to ES.

Note: The name of the station (PC station) in the project must be the same as the physical machine. The name ES is a random name (the initials of Engineer System - default name in PCS 7 for the configuration machine). You may use any name. The important thing is that the name in the project is the same as the name of the physical machine. When the project and the machine have the same name, the PC Station icon will have a yellow arrow .

Note: it is possible that the yellow arrow does not appear, even with the correct configuration.

• Select PC Station ES object and open Configuration.

• Insert Ethernet communication target for ES (IE General). It is in the catalog at Simatic PC Station\CP-Industrial Ethernet\IE-General SW V8.1. Add in position 1 of the PC Rack (index 1).

• IE General of ES with IP Address 192.168.0.2 and mask 255.255.255.0.

• Select PlantBus subnet.

• Insert WinCC Appl. on PC Index 2 - Select from catalog the SIMATIC PC Station\HMI\WinCC Appl. and drag to Index 2 from the PC rack. Save and compile HW Config. The compilation may take a few minutes. Close HW Config.
