OPC UA Subscription (dynamic)

The OPC UA Subscription (dynamic) Channel is an Inbound Channel, which is used to monitor data changes on an OPC UA Server (Environment Entry). For this purpose, each OPC UA Subscription (dynamic) Channel creates its own Subscription, which holds a list of monitored items. If one or more of these monitored items change their value, the OPC UA Subscription (dynamic) Channel will be triggered from the OPC UA Server and starting a Process Model.

The monitored items are Nodes from the Server Address Space of an OPC UA Server. The nodes that are monitored can be added dynamically to the list of monitored items. Therefore, the user has to create a process model that uses the script-API of the channel to modify the set of configured items.

Currently, this channel can be used for Object Nodes and VariableShape Nodes only.
