CIMPLICITYUsing Wait State Functionality Example
This example demonstrates how you can easily create a light that will flash to let you know when Trending has outstanding requests for data, requests that are outstanding for long enough to signal that there might be a problem.
Wait State Example Parameters
You expect Trending to retrieve data every 5 seconds.
A normal range for Trending to wait is up to 10 seconds.
Requests that are outstanding for over 10 seconds may indicate that there is a problem.
Therefore, you want CimView to signal an operator if there are requests that are outstanding for over 10 seconds.
Note: This example uses the following Expression lines, which are already configured for the chart.
| Line 1 | S90_350 |
| Line 2 | S90_500 |
| Line 3 | S90_900 |
Configuration steps include:
| Step 1 | Create a screen level variable. |
| Step 2 | Activate Trending's wait state feature. |
| Step 3 | Configure an EnteringOutstandingLoggedRequestState event. |
| Step 4 | Configure a LeavingOutstandingLoggedRequestState event. |
| Step 5 | Configure an object to report Trending's request status. |
| Step 6 | Test the request configuration at runtime. |
