TriggeredWriteA block for writing data to items on an OPC server at intervals determined by an external Boolean signal (trigger) |

Information
This block writes data of type Integer 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 writeExternalInteger is called from within the block.
Relevant Parameters
- itemName: which OPC item to write data to
- 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: an Integer input, 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
