Abstract:
1. A method for operating a technical installation including a plurality of field devices for monitoring and controlling components of the technical installation, at least one process control computer for monitoring and controlling the technical installation, and at least one communication channel by which the field devices are connected to the process control computer, the field devices for transmitting to the process control computer measurement data which arise in the technical installation and describe the operating state of at least one of the components and for receiving control commands from the process control computer, wherein the measurement-data and control commands are transmitted between at least one portion of the field devices and the process control computer via the communication channel using a Transmission Control Protocol/Internet Protocol (TCP/IP), wherein the process control computer includes a web server for connection to at least one of the Internet and an intranet, and wherein at least one of operator control and monitoring functions of the technical installation implemented in the process control computer by software, are executed using a client computer including an Internet browser and is connected to at least one of the Internet and the intranet, by access to the process control computer, the method comprising: assembling the at least one of operator control and monitoring functions from software components including directly executable software code, each software component further including a respective interface which is usable to set up at least one of a connection from a first software component to a second software component, a connection to the web server, and a connection to at least one of a sensor and actuator, the interfaces being compatible with one another such that setting up the connection does not require any alignment of signals transmitted via the connection, wherein at least one of inputs and outputs on the interface of the first software component are directly connectable to at least one of outputs and inputs on the interface of the second software component; and executing at least one of the operator control and monitoring functions assembled from at least two software components, without any compilation and loading operation taking place for this at least one of operator control and monitoring function beforehand on that computer on which this function is executed.
