Out[1]:=
Information
This block writes data from multiple items of type of type Boolean from the OPC server it is connected to. It inherits the properties of the partial model Sampler, which contains parameters such as samplePeriod and itemName that determine how often and to which OPC items the data should be written.
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 items
- startTime: when the block should start to write data
- 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
