DIAGNOSEVERFAHREN FÜR EIN NACH DEM AS-INTERFACE STANDARD AUSGEFÜHRTES FELDBUSSYSTEM

摘要

The method involves activating slave modules (S1-Sn) e.g. measuring sensors, by a master module (M) by using telegrams addressed for the slave modules to obtain diagnosis information about a condition of the slave modules. A diagnosis module is selected from diagnosis modules (D1-Dn) in the slave modules. The diagnosis information are read from the diagnosis module. The diagnosis information from the slave modules are fed back to the master module. The diagnosis module is selected based on the telegrams and actual operating conditions of the slave modules.
