Example
In this example the function is programmed in ladder diagram (LD). The same POU header is used
for all programming languages.
GVL
In the global variable list, you define variables that can be accessed by all POUs in the project.
DUT
The DUT F174_PulseOutput_DataTable_8_Values_DUT is predefined in the FP Library and can
be used as a sample.
POU header
All input and output variables used for programming this function have been declared in the POU
header.
LD
ST
When programming with structured text, enter the following:
IF DF(X0_bMotorSwitch) THEN
F174_PulseOutput_DataTable(s_dutDataTable := dutDataTable4, 4);
