A partial model that is used in the sampler blocks for reading and writing data to an OPC server.
TriggeredSampler provides the basis for establishing a link to the OPC item determined by parameter itemName. This is done by calling the external function addItem. Once the link is established, it becomes possible for the blocks to either read data from or write data to the item on the server they are connected to.
TriggeredSampler, unlike Sampler, has a Boolean input signal (trigger) that determines when sampling should occur. This is useful for irregular sampling of data, for example.
Description: The OPC item that data should be written to or read from
