printf

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Display a trace output.

Inputs

Input	Data Type	Range	Unit	Default	Description
FMT	STRING				Trace message.
ARG1.ARG4	DINT				Numerical arguments included in the trace.

Outputs

Output	Data Type	Range	Unit	Description
Q	BOOL	FALSE, TRUE		Return check.

Remarks

• This function works like the printf function of the C language, with a maximum of four integer arguments.
• Use the pragmas A compiler directive communicating additional pragmatic information. Pragmas are processed at compile time, not at run time. They pass information to the compiler. in the FMT trace message to represent the arguments according to their left to right order:

%ld    signed value in decimal
%lu    unsigned value in decimal
%lx    value in hexadecimal

• The trace message is displayed in the LOG window with runtime In computer science, runtime (or run-time) describes the operation of a computer program, the duration of its execution, from beginning to termination (compare compile time). In KAS, runtime refers to the virtual machine that manage the program written in a computer language while it is running. messages.
• Trace is supported by the KAS Kollmorgen Automation Suite Simulator.

Example

(* i1, i2, i3, i4 are declared as DINT *)4
i1 := 1;
i2 := 2;
i3 := 3;
i4 := 4;
printf ('i1=%ld; i2=%ld; i3=%ld; i4=%ld', i1, i2, i3, i4);

Output Message

i1=1; i2=2; i3=3; i4=4;
