This block writes data of type Real from the OPC UA server it is connected to. It inherits the properties of the partial model Sampler, which contains parameters such as samplePeriod, nodeID, nodeNamespace, and nodeIDType that determine how often and to which OPC node the data should be written. Only scalar nodes can be written to; i.e. no array or matrix nodes are supported.

At every sampling instant, external function  writeExternalReal is called from within the block.

Relevant Parameters

• samplePeriod: determines how often to sample data from the OPC node
• startTime: when the block should start to read data
• nodeID: which OPC UA node to write data to (ID value should always be inside quotes)
• nodeNamespace: which namespace the node is located in
• nodeIDType: which ID type to use, numeric or string
• uaRealType: which OPC UA Real type to use when writing data
• uMax: if useUMax is true, then uMax is the upper limit for the written data
• uMin: if useUMin is true, then uMin is the lower limit for the written data
• useUMax: if true, respect upper limit uMax
• useUMin: if true, respect lower limit uMin

Interfaces

• u: a Real input, which is the signal to be sampled and written to the OPC UA server
• serverID: the connector that connects the block to the OPC UA server component
