| | | WEB-EPAM Using WEB-EPAM makes every visualisation application created with EPAM automatically WEB-enabled. For this, a Java applet is loaded via the integrated WEB professional server of SUPPLIER OF PLC line devices, which presents a 1:1 image of the visualisation process in any Java-compatible standard browser, thus enabling the system to be controlled remotely. Remote maintenance and visualisation thus become child's play. The identification process is implemented using a user/ password so that only authorised persons are allowed access. The terminal client/server technology used transfers only changed screen contents and mouse/button events to the browser in compressed form thus reducing the bandwidth load. The great advantage of this technology is that the project does not have to be compiled. Only one version of the project on the target system is required, which does not have to be converted again into a WEB project when changes are made. This is a tremendous advantage with maintenance work and also saves memory on the target system. It also ensures that a 1:1 image of the process visualizsation is available locally at all times, even if this has been enhanced with user-specific functions (e.g. ANSI-C). User entries can be traced and corrected if required. | | |
