Placeholder function
Bring your i4scada SmartEditor project to the next level! Read this article for a quick introduction to the i4scada SmartEditor Placeholders.
The i4scada SmartEditor placeholder function allows the user to reuse visual elements, based on dynamic parameter exchange and dynamic signal names.
The placeholder function can be strongly related to the previously presented Modal dialogs.
Currently, within the i4scada SmartEditor tool, we distinguish 3 main placeholder parameters:
The Parameter Control [PC:]
The Object ID Parameters [OID]
The Local Object ID Parameters [LocalOID]
The Parameter Control [PC:]
The PC placeholder will be replaced at run-time with the value of the predefined parameters, of the i4scada SmartEditor extension. For a step based tutorial regarding the [PC:...] placeholder, please also visit the tutorial Using Parameters in Modal dialogs.
The Object ID Parameters [OID]
The OID placeholder will be replaced at run-time with the value of the Object ID parameter, of the i4scada SmartEditor extension. For a step based tutorial regarding the [OID] placeholder, please also visit the tutorial Using the Object ID [OID] parameter in Modal dialogs.
The Local Object ID Parameters [LocalOID]
Similar to the previous placeholder, the [LocalOID] parameter will be replaced at run-time with the value of the LOCAL Object ID parameter, of the i4scada SmartEditor extension.
