When X0_bMotorSwitch turns to TRUE the function is executed.
Error flags
Example
In this example the function has been programmed in ladder diagram (LD) and structured text (ST).
GVL
In the global variable list, you define variables that can be accessed by all POUs in the project.
DUT
The DUT F168_PulseOutput_Trapezoidal_DUT is predefined in the FP Library.
POU header
All input and output variables used for programming this function have been declared in the POU
header.
Body
LD
ST
When programming with structured text, enter the following:
IF DF(X0_bMotorSwitch) THEN
F168_PulseOutput_Trapezoidal(s_dutDataTable := dutTrapez,
n_iPulseOutputChannel := 0);
END_IF;
