Information
A partial model that is used in the sampler blocks for reading and writing data to an OPC UA server.
Sampler provides the basis for establishing a link to the OPC node by determining parameters nodeID, nodeNamespace, and nodeIDType. These are used later as input arguments for the different blocks.
The sampling rate and at what time sampling should start are determined by parameters samplePeriod and startTime.
