Abstract: 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.

Abstract: An apparatus for servicing a field device from a remote terminal, wherein the field device has an onsite display/servicing capability and is connected to a fieldbus of process automation technology. The remote terminal and the field device communicate with one another via at least one defined transmission protocol. A web server is integrated in the field device, in a Plant Access Point or in the remote terminal; the web server provides all requested device information, which is the so called firmware, of the field device in the form of dynamically produced contents to the remote terminal. A communication driver specific to the applied transmission protocol and a browser are integrated in the remote terminal.
