For system objects, there may be important state that the user should see in the active status (e.g., "Ground in a network with isolated neutral", "Switching on a sectionalizer", "Opening the emergency exit door"). Events reporting this important state are opening events. Events reporting the end of an important object state are closing events.

127 +[[image:Screenshot 2025-12-10 at 21.45.18.png]]
290 290  
291 - <h4>Method 1: Flashing by tag</h4>
129 +Fig. 2.5 - Site settings
292 292  
293 - <p>Use this method if the information model is not configured or not planned. Steps:</p>
294 - <ol>
295 - <li>
296 - <strong>Set up an event</strong> with the triggering formula, for example, connection loss
297 - (<code>ti40027171 != 1</code>) or restoration (<code>ti40027171 == 1</code>) — any tag
298 - registered in the system can be used (Figure 2.13).
299 - </li>
300 - <li>
301 - <strong>Create a calculated tag</strong> with the formula <code>[devstatusNN]</code> where
302 - NN is the device ID (Figure 2.14). The tag to be used for the designated purpose may get
303 - its value from a real device or may be based on other tags.
304 - </li>
305 - <li>
306 - <strong>Set up an object on the diagram</strong>, referencing the calculated tag from step 2
307 - in its rules (Figure 2.15).
308 - </li>
309 - <li>
310 - After saving the diagram and updating the configuration, if the status of the NN device
311 - changes, the system will start flashing the bound diagram object until it is acknowledged.
312 - </li>
313 - </ol>
131 +3. In the opened window, go to Privacy and security → Site settings → Additional permissions → Content → Additional content settings → Sound, and select Allow (see Fig. 2.6).

497 - <p>Figure 5.1 shows the event <em>Switch position f.1.1 (1QF1)</em> configured as a one-position event bound to an IM object and a device. The formula <code>ti11013008 == 2</code> triggers the event when tag 11013008 equals 2. Dead time is 0 (no delay), acknowledgement is enabled, and the default sound plays 5 times.</p>

498 498  
499 - <h4>Example 2: Event on device status change (with return)</h4>
241 +A) Set up an event that will contain the formula, for example, connection loss (ti40027171 != 1) or restoration of connection (ti40027171 == 1) with the device (see Fig. 2.13). The formula can refer not only to the device status, any tags registered in the system can be applied here, in this example, the device status is used as a special case. For more details on the available formulas and expressions, please refer to the** Setup Manual. **
