Abstract

A device for planning a production unit with a production building and a manufacturing facility, wherein the manufacturing facility has machines with equipment for automation systems integrated at least partially in a communication network, wherein the device has a product data management system, in which data relating to the product to be manufactured and further manufacture-related data is stored in a database and with planning tools that are called up from a planning platform which allow at least partially virtual mapping of the product, the production building and the manufacturing facility by accessing the database, a network planning tool for the communication network being integrated in the planning platform, data characterizing the communication network being available based upon the product data management system.

Claims

1. A device for planning a production unit for manufacturing a product, the production unit having a production building and manufacturing facilities, wherein the manufacturing facilities are connected by way of a communication network and are equipped with automation systems, the device comprising:

a product data management system comprising a database in which data relating to the product to be manufactured and further manufacture-related data are stored, the product management system comprising a planning platform comprising planning tools for generating a virtual mapping of the product, the production building and the manufacturing facilities by accessing the database;

a network planning tool integrated in the planning platform for receiving network planning data characterizing the communication network as input, wherein results from the network planning tool comprise end-to-end delay times achieved for specified logical configurations of the automation devices, wherein the results take into account actual influences of the communication network itself in the planning for the production unit; and

a monitoring interface for displaying planning status information in the planning for the production unit.

2. The device as claimed in claim 1, wherein the planning platform has a plug-in architecture and the network planning tool is integrated as a plug-in.

3. The device as claimed in claim 1, wherein data characterizing the communication network as input for the network planning tool comprises:

a list of network elements that can be used,

positions of network adapters of all automation devices,

a logical configuration of the automation devices, from which the communication protocols used result and therefore the induced network load,

a logical grouping of the automation devices,

quality-of-service requirement,

maximum permissible costs,

a restriction for laying a network cable, and

a network topology criteria.

4. The device as claimed in claim 1, wherein the results of the network planning tool further comprise:

switches used with their position and a reference to their type in a material list,

network data with cable data including references to the cable type in the material list and an accurate description of the cable run,

the utilization of network cables, and

overall costs.

5. The device as claimed in claim 3, wherein the results of the network planning tool further comprise:

switches used with their position and a reference to their type in a material list,

network data with cable data including references to the cable type in the material list and an accurate description of the cable run,

the utilization of network cables, and

overall costs.

6. The device as claimed in claim 1, wherein the monitoring interface is configured as a remote-procedure-call for requesting status as asynchronous polling.

7. A method for planning a production unit for manufacturing a product, the production unit having a production building and manufacturing facilities, wherein the manufacturing facilities are connected by way of a communication network and are equipped with automation systems, the method comprising:

storing data relating to the product to be manufactured and further manufacture-related data in a database of a product data management system, the product management system comprising a planning platform comprising planning tools;

calling up by the product data management system the planning tools from the planning platform;

generating by the planning tools a virtual mapping of the product, the production building and the manufacturing facilities, wherein each planning tool obtains required product information or unit information from the database of the product data management system; and

planning the communication network of the production unit by receiving network planning data characterizing the communication network as input for a network planning tool integrated in the planning platform, wherein results from the planning of the communication network by the network planning tool comprise end-to-end delay times achieved for specified logical configurations of the automation devices, wherein the results take into account actual influences of the communication network itself in the planning for the production unit; and

displaying planning status information for the production unit.

8. The method as claimed in claim 7, further comprising:

inputting in the product data management system, wherein the inputted data is available for the network planning tool, one or more of the following;

a list of network elements that can be used,

positions of network adapters of all automation devices,

a logical configuration of the automation devices, from which the communication protocols used result and therefore the induced network load,

a logical grouping of the automation devices,

quality-of-service requirement,

maximum permissible costs,

a restriction for laying a network cable, and

a network topology criteria.

9. The method as claimed in claim 7, further comprising:

inputting in the product data management system, wherein the inputted data is available for the network planning tool, all of the following;

a list of network elements that can be used,

positions of network adapters of all automation devices,

a logical configuration of the automation devices, from which the communication protocols used result and therefore the induced network load,

a logical grouping of the automation devices,

quality-of-service requirement,

maximum permissible costs,

a restriction for laying a network cable, and

a network topology criteria.

10. The method as claimed in claim 7, further comprising:

invoking a remote-procedure-call for requesting the status information as asynchronous polling.

11. The method as claimed in claim 7, further comprising:

providing at least one of the following additional results via the product data management system generated based upon the network planning tool;

switches used with their position and a reference to their type in a material list,

network data with cable data including references to the cable type in the material list and an accurate description of the cable run,

the utilization of network cables, and

overall costs.

12. The method as claimed in claim 7, further comprising:

providing all of the following additional results via the product data management system generated based upon the network planning tool;

switches used with their position and a reference to their type in a material list,

network data with cable data including references to the cable type in the material list and an accurate description of the cable run,

the utilization of network cables, and

overall costs.
