| 20100287277 | METHOD FOR MONITORING A PROCESS SYSTEM HAVING A FIELD BUS IN THE PROCESS AUTOMATION TECHNOLOGY - A method for monitoring a process plant having a fieldbus of process automation technology, via which a number of field devices exchange with a process control unit PLC telegrams in regular data traffic for process control. The following method steps are executed: telegrams transmitted via the fieldbus to the process control are tapped by a monitoring application, which performs a testing of the telegrams for data relevant for the monitoring application; data relevant for the monitoring application are processed as actual values in a process modeling application, which is part of the monitoring application; and when a significant deviation is determined between desired and actual values, an error signal is generated. | 11-11-2010 |
