NumericToTrigger

Description

The NumericToTrigger component is used to trigger a topic when a change is made to one of its entries. It thus makes it easy to create actions from a rising value for example (without retriggering it on a decrementing value for example).

It also prevents the topic from being retriggered directly after its activation by defining a "timeout" period during which it cannot be triggered, even if there are changes to its entries.

Implementation

• Copy / paste the NumericToTrigger component into a WireSheet
• Set the desired number of entries from the "SetlnputCountValue" action
• Link the properties of the Numeric values to be monitored to the InX properties of the component
• Set the timeout period from the "MinUpdateTime" slot
• Define the state changes that the NumericToTrigger must take into account from the FireChangeOnState property

Properties

• MinUpdateTime: Sets the minimum time delay between two activations of the ValueChanged topic
• FireChangeOnState {Increment, Decrement}: Defines the InX state changes to take into account (Increment corresponds to a rising input, Decrement means a decreasing value).
• InputCount: The number of inputs managed by the component
• ln_X: dynamically created slots to connect the monitored points

Actions

• SetlnputCountValue: Sets the number of entries to handle in the NumericToTrigger component. Adds or deletes StatusNumeric in_X slots.

Topics

• ValueChanged : Triggered on the occurrence of a state change on one of the ln_X inputs that meets the FireChangeOnState condition. The minimum time between two triggers is set by the MinUpdateTime.
