AnyNumber (STRUCT)

TYPE AnyNumber : STRUCT

AnyNumber represents a numeric value either as value or POINTER TO value with variable base type.

Supported base types:

  • SINT (8bit -128 .. 127)

  • USINT (8bit 0 .. 255)

  • INT (16bit -32768 .. 32767)

  • UINT (16bit 0 .. 65535)

  • DINT (32bit -2147483648 .. 2147483647)

  • UDINT (32bit 0 .. 4294967295)

  • REAL (32bit float)

  • DOUBLE (64bit float)

The base type is initialized to AnyNumberTypes.TYPE_NONE, which will be detected as invalid base type on read operations, so ensure to set the base type properly.

Using the POINTER TO value representation requires the POINTER TO value <> 0 (set u.p.p* according to baseType). The POINTER TO value is initialized to 0, which will be detected as invalid on read / write operations, so ensure to set the POINTER TO value properly.

There are functions to support certain operations using AnyNumber:

Initialization of AnyNumber is a bit eloquent, but no matter of this simple:

Example:

/// AnyNumber base type REAL with value representation

any1_REAL_value : DNP3.AnyNumber := (

baseType:=DNP3.AnyNumberTypes.TYPE_REAL, /// init the base type

u:=(val:=(valREAL:=42)) /// init the value

);

/// AnyNumber base type REAL with POINTER TO value representation

/// The value to point to …

any2_value : REAL;

/// Now the AnyNumber pointing to any2_value

any2_REAL_POINTER_TO_value : DNP3.AnyNumber := (

baseType:=DNP3.AnyNumberTypes.TYPE_REAL, /// init the base type

isPtr:=TRUE, /// select POINTER TO value representation

u:=(p:=(pREAL:=ADR(any2_value))) /// init the POINTER TO

);

Data holding either the value or POINTER TO value according to baseType. For value representation access u.val.val* For POINTER TO value representation access u.p.p* according to baseType.
