Core Concepts

Instances

Instances inside WDX are your runtimes. Within every instance you can have structure of different Data Schemas, that you can use for example in eDesign.

Instance Types

WDX supports different instance connection types for maximum flexiblity. We support these protocols at the moment:

• eWeb Protocol – connects to CODESYS 3 variables.
• Virtual Adapter – defines and manages variables within the WDX Data Layer.
• MQTT Adapter – supports data exchange via MQTT.
• OPC-UA Adapter – integrates with OPC-UA protocols.
• Modbus TCP – enables Modbus TCP communication.
