| colspan="5" bgcolor="#AADDDDD" | Input
|-
| Old Input        
| Returns the previous state of the port input. Note that the value is actualized only after the first detected change        
| {s:atStatus}        
| clBina..        
|  
|-
| New Input        
| Returns the new state of the port input after each detected change.        
| {s:atStatus}        
| clBina..        
|  
|-
| Test Input        
| Open a input monitor window showing real-time port input with the current settings. Use for testing at designtime.        
| {s:atDesign}        
| Boolean        
|  
|-
| Trigger Once        
| Defines whether the element can be triggered multiple times, while the parent event is active. If the property value is 'true' only the first triggering is registered

| Boolean        
|  
|-
| colspan="5" bgcolor="#AADDDDD" | Runtime Status
|-
| Is Triggered        
| Indicates whether the element has been triggered at least once since activation of the parent event.Triggering occurs only in the 'Input Detection' working mode        
| {s:atNormal}        
| Boolean        
|  
|-
| Triggering Time        
| Indicates the local event time of the last element triggering. Triggering occurs only in the 'Input Detection' working mode.
