Delimitation

The guideline defines a so-called "active message function". This is a communication mechanism describing a new possibility of generating and communicating system data which does not interfere with existing automation concepts. The communication channel described allows entities inside and outside the system to carry out a diagnosis of devices in a system without affecting the sequences defined by the relevant automation technique (hereinafter also called real-time operation). Nonetheless, it is possible for the automation concept to integrate the function described.

Objective

Drives as components of automation-technical systems are intelligent field devices containing manifold information the evaluation of which not only provides indications about the particular state of the drive. By correlation and linking of the individual states the user and the system manufacturer obtain information about the state of the entire system. As a result, rapid diagnosing in the case of irregular system states, optimization of process operations, preventive maintenance and minimum spare parts stocks are ensured.

The guideline also covers constellations which are composed of drive units obtained from different manufacturers.

Use of XML

Section 1 to Section 4 of this guideline deal with the diagnostics of drives. Section 5 to Section 7 describe how the diagnostic contents are implemented on the basis of XML which describes mechanisms for providing data. The schemes given are, however, also suitable for configuration purposes.
