WOLFRAM SYSTEM MODELER
This block reads data from multiple items of type Boolean from the OPC server it is connected to. Unlike the read blocks that have a parameter for setting the sample period, the triggered read blocks read 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 readExternalReal is called from within the block.
