The default resolution is 10 bit.

When increasing the resolution from 10 to 12 bit, the range of the analog output values change from 0..1023 to 0..4095.

Input:

res : int (10,12)

Selects the resolution for the analog output.
 

Returns: INT

Declaration:

FUNCTION boardSetAOResolution : INT;
VAR_INPUT
  res : INT;
END_VAR;

Example:

INCLUDE rtcu.inc
 
PROGRAM test;
// Selects 12 bit output:
boardSetAOResolution(res := 12);
 
BEGIN
END;
END_PROGRAM;
