I&M (Identification and Maintenance) Functions were created to help manage devices more easily. They are based on Ident Numbers.
I&M-enabled devices internally manage a profile ID, a device ID and a manufacturer and access www.profibus.com using an engineering tool to locate relevant files, download them and save them locally. The tables aid in the different life cycle phases of a product, such as project planning, commissioning, parameter setting, diagnostics, repair, firmware update, asset management, and audit trailing. They are made available in machine-readable form (XML document) and in human-readable form (HTML document).
Information about the features of a device and its use as well as information about the manufacturer is available. If an inquiry from an end user occurs, the transmitted manufacturer ID is used to filter out the information stored in the table and transmit it to the tool of the end user.
Since the information is available online and not permanently stored in the device, this ensures that information is always up-to-date. For example, if the contact address of a manufacturer changes, the new information is immediately available.
If you do not have a manufacturer ID / vendor ID yet, you can request one by sending an e-mail to certification[at]profibus.com. To change your company information please send an e-mail to certification[at]profibus.com.
To illustrate the functionality of I&M Functions PI offers a test tool. This simulates access to the I&M Data, the evaluation of the I&M Parameters and the language-specific representation of the data.
