Valve cluster and a communication method therefor
A valve cluster and a communication method operate with valves. arranged in a row direction against each other and with a control means for the control and/or monitoring of the at least one internal component included in the valve cluster or at least one external component connected with the valve cluster, more particularly a valve, the control means comprising a Web server for providing monitoring data relative to the at least one component for a monitoring means at the communication interface. The monitoring means requests monitoring data from the Web server, whereupon the Web server transmits a page data set for a monitoring page able to be displayed by a browser of the monitoring means in a markup language. The monitoring means executes the request program code included in the at least one page data set and sends at least one message for requesting reload data, which the Web server transmits to the monitoring means in a manner dependent on a structure and/or a status of the valve cluster and/or of the at least one component by way of the communication interface so that the monitoring means may generate and/or update the monitoring page by the execution of generation program code contained in the page data set or the reload data.
1 . A valve cluster including fluid power valves arranged in a row direction against each other and a control means for the control and/or monitoring of at least one internal component comprised in the valve cluster or at least one external component connected with the valve cluster, the control means comprising a Web server for the provision of monitoring data relevant to the at least one component for a monitoring means at a communication interface, wherein the monitoring data, which are provided by the Web server to the monitoring means on request, comprise at least one page data set for a monitoring page able to be represented by a browser of the monitoring means in a markup language, and wherein the at least one page data set contains request code on whose execution by means of a processor the monitoring means transmits, for the generation of the monitoring page, at least one message for the request of reload data to the Web server, and wherein the control means is adapted to transmit the reload data on the basis of stored data modules in a manner dependent on a structure and/or a status of the valve cluster and/or the at least one component by way of the communication interface, and wherein the at least one page data set or the reload data comprise generation program code on whose execution by means of the processor the monitoring means dynamically generates and/or updates the monitoring page on the basis of the reload data.
2 . The valve cluster as set forth in claim 1 , wherein the at least one component comprises a valve in the valve cluster and/or at least one external actuator connected with an input and/or output interface and/or at least one sensor connected with an output and/or input interface.
3 . The valve cluster as set forth in claim 1 , wherein the at least one page data set constitutes a component of a Website for the at least partial representation of the valve cluster and/or of the at least one component, the monitoring means dynamically generating and/or updating the Website by the execution of the request program code and the generation program code interactively with the control means.
4 . The valve cluster as set forth in claim 1 , wherein the at least one page data set or the reload data comprise data for the generation of at least one navigation element indicated on the browser that on activation of the at least one navigation element the request program code or the generation program code transmits a message for requesting a second monitoring page to the Web server, and wherein the Website transfers a page data set with a second request program code able to be executed by the processor of the monitoring means and/or a second generation program code for requesting second reload data and for dynamic generation and/or updating the second monitoring page.
5 . The valve cluster as set forth in claim 1 , wherein the generation program code and/or the request program code is adapted for cyclical updating the monitoring page.
6 . The valve cluster as set forth in claim 1 , wherein the at least one page data set comprises at least one basic structure of the monitoring page which on execution of the generation program code is filled with contents on the basis of the reload data.
7 . The valve cluster as set forth in claim 6 , wherein the basic structure comprises at least one void table with at least one table line.
8 . The valve cluster as set forth in claim 1 , wherein data for the at least one page data set and/or the reload data are able to be loaded more particularly by way of the communication interface into the control means.
9 . The valve cluster as set forth in claim 1 , wherein the data modules include graphic representations of the at least one component comprised in the valve cluster or connected with the valve cluster.
10 . The valve cluster as set forth in claim 9 , wherein the Web server transmits the graphic representations as segments of an overall representation and generation program code is designed for combining the segments to constitute an overall representation.
11 . The valve cluster as set forth in claim 9 , wherein the graphic representations comprise a graphic events table of the respective operational or error status of the component for a predetermined or preset period of time.
12 . The valve cluster as set forth in claim 9 , wherein the generation program code and/or the request program code is designed to represent a graphic update display on the monitoring page.
13 . The valve cluster as set forth in claim 1 , wherein the request program code and/or the generation program code are constituted by separate program parts or by a single program.
14 . The valve cluster as set forth in claim 1 , wherein the request program code and/or the generation program code comprise at least one JAVA applet and/or JAVA script.
15 . The valve cluster as set forth in claim 1 , wherein the request program code makes available a UDP interface and/or an HTTP interface.
16 . The valve cluster as set forth in claim 1 , wherein by way of the Web server an email interface of the control means is able to be configured.
17 . The valve cluster as set forth in claim 1 , wherein the communication interface and/or the Web server is able to be secured for access security using a password.
18 . The valve cluster as set forth in claim 1 , wherein the communication interface is designed for receiving control instructions of a master control means.
19 . The valve cluster as set forth in claim 1 , wherein the communication interface comprises a bus interface and more especially a field bus interface and/or an ethernet interface.
20 . A communication method for a valve cluster having valves lined up in a row direction against each other and a control means for controlling and/or monitoring at least one internal component comprised in the valve cluster or an external component connected with the valve cluster, the control means possessing a Web server for monitoring data with respect to the at least one component for a monitoring means at a communication interface, the method comprising the steps of:
requesting monitoring data by the monitoring means at the Web server,
transferring at least one page data set for a monitoring page able to be represented by a browser of the monitoring means in a markup language from the Web server to the monitoring means,
execution of request program code contained in at least one page data set by a processor of the monitoring means,
transmission of at least one message for retrieval of reload data at the Web server by execution of the request program code,
transmission of the reload data from the Web server to the monitoring means on the basis of stored data modules in a manner dependent on a structure and/or a status of the valve cluster and/or of the at least one component by way of the communication interface,
