Abstract:
At least one of the softening point and the dropping point of a substance is determined with a measuring instrument that comprises a sample chamber (4), a temperature sensor (16), a heater device (11), a means for providing temperature/time target values, an image-recording means (5) and a controller unit (17) with a processor unit. The heater device heats the sample chamber, the temperature sensor measures the temperature in the sample chamber, and the image-recording means captures a visual image of the interior of the sample chamber. A method using the measuring instrument has at least the steps of determining the change over time of the sample as a function of temperature based on the recorded image/time data and actual temperature/time data, and of determining the dropping- or softening point of the sample based on the observed change over time as a function of temperature.
Abstract:
To produce a controller or regulator (1), a control or regulation process (3) is first designed and simulated on a development system (20). The process source code (25) for a target system (2) arranged in the controller or regulator (1) is then generated, and also a description file (28, 29) in HTML and/or XML format which, among other things, describes the parameters for the controller or regulator (1). Tags which characterize the parameters are used in the description file (28, 29). The description file (28, 29) is then converted, in a web server generator (30), into data and source code (31, 34) for a web server (5) which can run on the target system (2). In this context, the web server generator (30) and/or web server (5) use/uses the tags to insert input and output elements which can be used for setting and reading the respective parameters. The present system can be used for easily producing an interface for controlling the process (3) running on the target (2), which interface can be used by any client computer (7) without special software.
Abstract:
A method for installation of a programmable protective function in a protective device for an electrical power distribution network, with the protective device having means for processing measured values from measurement appliances for the power distribution network, and having means for initiating switching commands by primary appliances for the power distribution network, and the protective function determining the switching commands on the basis of the measured values, when it is carried out, has the following steps: transmission of a description of the protective function from a remote function server via a communication link to the protective device, loading of the description in the protective device, and implementation of the loaded description of the protective function. A protective device according to the invention has means for receiving a description of a protective function via a communication link from a remote function server and has means for loading the description, wherein the loaded description of the protective function can be carried out in the protective device.
