Information
This block writes data from multiple items of type of type of type Boolean to the OPC server it is connected to. Unlike the write blocks that have a parameter for setting the sample period, the triggered write blocks write data when Boolean input signal trigger has a rising edge. The block inherits the properties of the partial model TriggeredSampler.
At every sampling instant, external function writeExternalReal is called from within the block.
Relevant Parameters
- itemName: which OPC items to write data to
Interfaces
- u: a Boolean array input of the same size as itemName, which is the signal to be sampled and written to the OPC server
- serverID: the connector that connects the block to the OPC server component
- trigger: a Boolean input that determines when the block should sample data from the input signal
Parameters (1)
