摘要:
The invention relates to a method for operating a proxy server device (1) connected to a field device (FG1–FGN), in addition to a proxy server device. The proxy server device can be connected to the field device and a user device (N1–NN) in order to respectively exchange electronic data in order to monitor and/or operate the field device. The electronic data consists of static data which is transmitted according to a first protocol standard and dynamic data which is transmitted according to a second protocol standard.
摘要:
A process control system includes an executive routine located at a first node of a process control system, one or more soft phases located at other nodes remote from the first node and communication software located in the each of the nodes to enable the executive routine to call and execute the soft phases that are at nodes remote from the first node. This operation may reduce loading or communication traffic on the batch executive node and enables the operator to interact with a soft phase at a workstation or node that is convenient to the operation of the soft phase, which makes the operator's task easier and results in faster execution of the soft phase.

摘要:
A system for communication between the software components of an optical metrology system is provided. For this system, an optical metrology tool is configured to have a graphical user interface (GUI) process and a control software process. The GUI process is responsible for user interaction. The control software controls the operation of the optical metrology tool (e.g., data acquisition, robotic wafer handling, etc.). The GUI and control software processes communicate using two named pipes. The first, or inbound pipe is used by the GUI process to send commands to the control software process. The second, or outbound pipe is used by the control software process to send result messages to the GUI process. This decouples the GUI and control software processes. This facilitates the use of GUI development environments and allows the GUI process and control software process to be hosted on separate computer systems in networked environments.
