Alerts

For displaying the alarm color on a symbol you don't have to connect to the value of a DPE and calculate a color which will then be displayed.

The smart wayto do this instead with WinCC OA is to connect to the config attribute _alert_hdl.._act_state_color using the dpConnect() function. In the work function the foreCol and/or backCol of the symbol is set.

The attribute _alert_hdl.._act_state_color already gives the current alarm color of the DPE, so there is no need for redundant calculations.

The texts for the alert direction are defined in the message catalogue sc.cat, the keywords are “entered” for the CAME text and “left” for the WENT text.

If you want to translate or change the texts which are shown in the AEScreen for the alert direction, you have to perform the following steps:

1. Copy the file sc.cat into the language-dependent msg directory in your WinCC OA project. This file is available with the texts in German, English and Russian.
2. Open the file with a text-editor
3. Change the texts for the keywords “entered” and “left”

If you want to translate the texts in the message catalog, you can use the Translator tool. You can find detailed information on this in the online help: Multilingual projects > Translator

You can use the following example to open the AES in a specific configuration in which no further interaction is required on the part of the operator.

In this example, the AES is opened with the (predefined) configuration "myAEScreen".

1. Create your own screen configuration (System management -> settings -> A&E - Row/Screen) e.g. myAEScreen with new alarm screen property myAlarmsand event screen property myEvents
2. 2) Start the alarm screen with the following command. The list of parameters is described in the WinCC OA Documentation.

   In the example the parameters are:

   Configuration = myAEScreen

   Module name = WinCC_OA-AES

   Action = AES_ACTION_AUTORUN

3. Open AEScreen with the myAEScreen configuration in the WinCC_OA-AES module and execute the queries of the two tables openAES("myAEScreen", "WinCC_OA-AES", AES_ACTION_AUTORUN);
