Class DataArithm
Version	1.0
Modified	08-MAR-2026 11:05:32.00

 User progammable object with data inputs and outputs.


 The object contains
   - four data inputs
   - six digital inputs
   - six analog inputs
   - four data outputs
   - six digital outputs
   - six analog outputs

 The function for digital and analog signals is similar to CArithm,
 DataArithm also has the possibility to handle data object references.

 A data object is connected to an input and is handled as a pointer in
 the c-code. The class of the data object has to be declared with a
 classdef statement in the code. If a dataobject of class MyClass is
 connected to the first data input Da1, the classdef declaration is

       classdef Da1 MyClass;

 Da1 is then used as a pointer to a struct of the MyClass object
 (pwr_sClass_MyClass)

       Da1->Temperature = 20;

 The classdef statement can also contain an alias name for the pointer

       classdef Da1 MyClass MyObject;

       MyObject->Temperature = 20;

 The analog and digital inputs and outputs can also obtain alias names
 with the alias statement

       alias d1 EngineStarted, od1 StartEngine;
       alias A1 Temperature;

       if ( EngineStarted && Temperature < 400)
         StartEngine = 1;

 If the the databuffer object is a general buffer object, e.g. Buff256, but
 should be casted in the code to a c struct, the structdef statement can be
 used.

       structdef Da1 MyStruct;

       Da1->Temperature = 20;

 where the struct MyStruct is defined in ra_plc_user.h

       typedef struct {
         pwr_tFloat32 Temperature;
       } MyStruct;

 DpDistribute, ApDistribute, DpCollect and ApCollect objects can be used
 to expand the number of inputs and outputs to the DataArithm.
