Web Server for Device Configuration
The Web interface on LOYTEC devices with a built-in web server provides an alternative to the Configurator tool for the maintenance personnel. It can be used to configure device and communication settings. It also provides extensive statistical information on the used communication protocols for analysis and troubleshooting. Backup and restore can also be operated on the Web interface.
LOYTEC devices with an Ethernet/IP interface display data point values and states on the Web interface coming from different communication networks or registers. The display contains a data point list, a tree view, and a breadcrumb navigation for fast access to subdirectories. The data point list shows the data point name, direction, type, data point state, the current value, and a description. All values are updated live. Data points can also be modified on the Web interface.
On LOYTEC devices with L‑WEB support, all available graphical user interfaces are listed on the Web interface and can be started with a mouse click. LOYTEC devices with AST™ functions (Alarming, Scheduling, and Trending) offer access to those functions over the Web interface.
An alarm summary page displays all currently active alarms of alarm data points, which can also be acknowledged, if configured so. The Web interface also provides access to a historical alarm log, which lists alarms and acknowledgements. If an inactive, acknowledged alarm disappears from the alarm summary page, the last transition is stored in the alarm log. The content of the historic alarm log can be exported to a CSV file on the Web interface.
The Web interface provides a scheduler page, which allows modification of schedules and calendar entries for exception days during run-time. For existing local schedulers, the Web interface supports the re-configuration of the scheduled data points. The changes become effective immediately and don’t require a reboot of the device. For adding or removing data points to or from a scheduler, no reboot is necessary either.
The trend log configuration page on the Web interface allows the reconfiguration of existing trend logs during run-time. This also includes the assignment of new data points. The changes become effective immediately and don’t require a reboot of the device. The trended data can be exported into a CSV file over the Web interface.
