PowerMAP Device Type Manager
Each device manufacturer has to set up configuration information detailing objects and data types accessible through the network. With PowerMAP/DTM setting up a ETHERNET Powerlink device is quite straight forward. It builds up the object dictionary for each device type and generates the appropriate electronics data sheets used during I/O configuration in a later phase.

Vendors of complex devices may need more flexibility than provided by a generic device type manager in spreadsheet like tables. infoteam Software therefore offers an additional generic class library, from which vendor specific DTM’s may be derived. This library is fully compliant with the latest DTM style guide of the FTD joint interest group and eases the development of setup and maintenance software for Powerlink devices.

• Device configuration based on FTD/DTM technology
• Library for advanced interactive user interfaces
• Full featured operation of complex devices
• Handling of parameters and recipes

PowerMAP I/O Configuration
Textfeld: • Fig. 1 I/O Configuration MappingTo set up an I/O configuration all device type information generated by the DTM is imported and all parameters are represented in a tree like structure. Browsing available objects from devices on the network, the application engineer defines the mapping of physical devices and their terminals to logical variables of the application program. Thus the independence of application programs written in one of the IEC 61131-3 languages from the IO assignment is preserved, greatly enhancing portability and reusability.

An open interface based on DTM technology allows for vendor specific device descriptions and dynamically extends the capabilities of the device library:

• Browser for distributed ETHERNET Powerlink I/O
• Multi-vendor capability
• Portable application programs
• Fully compliant with IEC 61131-3

PowerMAP Network Linking
infoteam PowerMAP introduces a complete new method of network configuration. It clearly separates the fieldbus used for distributed I/O from the same network used for communication between intelligent devices. A graphical data flow editor enables the engineer to pick the different controllers from the configuration tree and place them on its worksheet to display its logical interfaces exposed for access by other controllers.

To define all necessary communication between those controllers, only the available interfaces need to be identified by a simple select and connect action. The dataflow is displayed automatically by coloured lines, specifying the different types of data transmitted. All the underlying details of the local or distributed I/O’s are hidden freeing the engineer of all unnecessary technical information:

• Pick and place control objects from the configuration tree
• Select and connect their interface to specify the data flow

Online diagnostics and monitoring of data is part of the engineering environment. The complete communication between components of the machine or the process may be monitored using the same engineering tools. This makes maintenance easy and troubleshooting fast!
