| 摘要 |
The invention is concerned with a method for operating a process automation system (10) that is designed for controlling an industrial process and/or traffic-control signals. The system (10) comprises field devices (12, 14, 16) arranged in a field (26) of the process and a central controller unit (18) for controlling the process through the field devices (12, 14, 16). The central controller unit (18) generates control data (CDATA) for the field devices (12, 14, 16) by running a control program (42'). This control program (42') is provided as a browser executable application (42) that is designed to receive and process field data (FDATA) from the field devices (12, 14, 16) and to generate and send out the control data (CDATA). The central controller unit (18) executes an internet browser program (38) and the internet browser program (38) runs the application (42). |
