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.

Method for monitoring a process system having a field bus in the process automation technology

Method for operating a field device of process automation technology, wherein the field device is connected for communication with at least one servicing tool. In the case of a request by a servicing tool for access to the field device, the access allowed by the field device depends on the particular servicing tool which places the access request, and on the operating state, in which the field device is located.
