accLoggerToMem (Function)

Architecture:	X32 / NX32 / NX32L
Firmware version:	2.40 / 1.40.00

This function will move the contents of the logger to the memory.

The acceleration vectors will be stored in memory as 3 DINTs, where the first dint contains the x-axis, the second contains the y-axis, and the third contains the z-axis.

Input:

mem : PTR;

Address of destination data area.

size : DINT;

The size of the memory in bytes.

Output:

None.

Returns: INT

>0	- Number of bytes written.
-1	- General error.
-3	- Destination size too small to hold a single reading.

Declaration:

FUNCTION accLoggerToMem : INT;
VAR_INPUT
mem : PTR;
size : DINT;
END_VAR;

Example:

INCLUDE rtcu.inc

VAR
   buf      : ARRAY [1..3000] OF DINT;
   readings : ARRAY [1..100] OF DINT;
   i        : INT;
END_VAR;

PROGRAM example;
accOpen();
accLoggerSetConfig(buffer := ADDR(buf), size := SIZEOF(buf));
accLoggerStart();
BEGIN
   IF accLoggerLevel() > 800 THEN
      i := accLoggerToMem(mem := ADDR(readings), size := SIZEOF(readings));
      IF i > 0 THEN
          ...
      END_IF;
   END_IF;
END;
END_PROGRAM;
