JsonArrayForEach (Json Array For Each)
This component passes each value of a JSON array to it’s output slot in sequence, with an intermediate delay between each
item. An internal queue buffers the values. This may be used to process a list of items by linking the component to wiresheet
logic that performs a task with each item.
Figure 92. JsonArrayForEach properties
You add this selector to a station by expanding in the palette and dragging the JsonArrayForEach to a message router in the Nav tree.
In addition to the standard property (Enabled), these properties support the JsonArrayForEach.
| Property | Value | Description |
|---|---|---|
| Last Result | read-only | Reports the results of the alarm acknowledgment to allow for logging or post-processing activity. Example output:
|
| Last Result Time | read-only | Reports when the handler ran last. |
| Last Input | read-only | Reports the last message routed to a component. |
| Status | read-only | Reflects the current status of the component.
Ok indicates the JSON processed successfully. fault indicates the JSON did not process for any reason, such as invalid JSON or missing expected values in the JSON. |
| Out | read-only | The current array item, this will cycle once through each array item. |
| Numeric Out | read-only | Attempts to convert each item to a number as an out. |
| Boolean Out | read-only | Attempts to convert each item to a Boolean value as an out. |
| Default Between Items | true or false (default)

If true then the output slots are set to default values between each array item.
|
| Queue | read-only | The queue component which buffers the array items. |
