Timer for Binary Switch Button

[Shehryar Tariq]

I am trying to add a binary switch button to my dashboard that I can turn on manually through the dashboard and after X amount of seconds it turns off automatically. I do not see any parameters where I can change these settings. Are there any functions/settings/parameters that can enable me to do this timing functionality with a toggle switch? Can I get some help on this?

This is something that you should ideally do within your PLC program. If you are not using a PLC you can do it from the Mango backend using an event detector.

The reason for this is that if you close the tab/window, or if there is some sort of communication issue the command to turn the binary point back off will not get sent.

It is possible to do this from a dashboard, but I would not recommend it as per above.

Thank you for your response but I am not using a PLC. Can you please explain what do you mean by using backend Mango? I thought event recorder is only for getting events, I don't think it can trigger anything, can it?

What I intend to do is that I have a toggle switch shown above, and I want it to automatically close once I manually turn it on after a certain time delay

To be more explicit about how to do this with an event detector -

• Add a binary state detector to your binary data point
  

• Under the state tab, choose the true state and set the duration to X seconds

• Save event detector

• Go to event handlers page

• Add a "Set point" event handler

• Under the "Set point" tab choose your binary point

• Under the "Event types" tab select your binary state event
  

• Under the "Active action" tab, choose "Set to static value" and set the value to false

• Save event handler

The event detectors are used to monitor for certain conditions and trigger an event/alarm yes. But you can hook up event handlers to these events to perform actions.

Something that might be useful - you can create a single event handler that you can attach to multiple event detectors.

• Change the event handler to "Set to scripted value"
• Add this script -

var points = DataPointQuery.query('eq(id,' + event.referenceId1 + ')');
points[0].runtime.set(0);
return UNCHANGED;

This will make the handler lookup the point which triggered the event and set that point back to zero.
