Change Values of Signals Using C Function Block and Buses

This example shows how to use buses with a C Function block. In this example two Constant blocks supply values. These signals are combined using a Bus Creator block. Code in the C Function block changes the values of these signals. Using a Bus Selector block, the values are displayed separately in two Display blocks.


The Output Code pane contains code that changes the values of the signals.

Add the symbols used in the code to the Symbols table. To use buses with a C Function block, set the Type of the symbol to Bus: SimpleBus.
