Beacon Light Service for Simatic WinCC<\/p>\n\n\n\n

<\/div>\n\n\n\n

The SCADA system Simatic WinCC shows alarms that occur by default on the screen in an alarm control. System operators often have a need to receive alarm notifications using light indication, possibly with different color display. The Beacon Light Service gives, in a simple and clear way, the operators the opportunity to get alarm indication with different color display, on a light tower with up to 5 different colors.<\/p>\n\n\n\n

Method of operation<\/h3>\n\n\n\n

Swappcon ApS has developed \"Beacon Light Service\" as an external service application that always runs in the background when WinCC Runtime is active. <\/p>\n\n\n\n

The \u201cBeacon Light Service\u201d application uses Central Signaling Device tags to indicate alarm colors in the light tower. A Central Signaling Device tag is called a CSD tag, and is explained in the following:<\/p>\n\n\n\n

In the WinCC alarm configuration module, a CSD tag is attached to the individual alarm message types. A CSD tag is a binary tag in WinCC that can assume the values 0 or 1. When an alarm belonging to a Message type is active, the corresponding CSD tag will assume the value 1. A CSD tag is reset when all alarms belonging to the Message type has been acknowledged. However, the configurator of the alarm system can choose that it is only the operator who must manually reset the associated CSD tags.<\/p>\n\n\n\n

In the \"Beacon Light Service\" application, a correlation is configured between the colors of the light tower and the CSD tags used. The configuration is done using a simple setup application. When the application is configured and the \"Beacon Light Service\" application is started the 1st time, the user does not need to worry about the application anymore. It will automatically be active when WinCC Runtime is active, and automatically start up as a service when Windows is restarted.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Alternative use<\/h3>\n\n\n\n

Although the \"Beacon Light Service\" application has been developed for the purpose of indicating alarm display, it can also be used in other contexts. The application associates a binary tag with a certain color in the light tower, and therefore a CSD tag can be replaced with any binary tag from the WinCC configuration. Important automation processes or information can thus be indicated using a light signal, if these can be associated with a binary tag in WinCC.<\/p>\n\n\n\n
