Mapping rules from data type in CSP+ for machine to the OPC UA DataType are shown in Table 81.

Table 81 – Mapping Rules between Data Type in CSP+ for Machine and OPC UA DataType

No.

Data type in CSP+ for machine(Left: Classification, Right: Data type)

OPC UA DataType

Remarks

1.

Boolean type

BOOL

Boolean

Map "0" in the CSP+ for machine to "FALSE" for OPC UA and map "1" in the CSP+ for machine to "TRUE" for the OPC UA.

2.

Binary type

BIN8

Int16

The intention "Display values in bit unit" by the binary type is described by the ValueAsText Attribute.

Example: Set the ValueAsText Attribute to "00111010" in BIN8 or "0000000000111010" in BIN16 for the value 58 (0x3A).

3.

BIN16

Int16

4.

BIN32

Int32

5.

BINx

(x = 1 to 15)

Int16

6.

Bit string type (Hexadecimal)

BYTE

UInt16

ValueAsText Attribute is used to describe hexadecimal.

Example: Set the ValueAsText Attribute to "0x3A" in BYTE or "0x003A" in WORD for the value 58 (0x3A).

7.

WORD

UInt16

8.

DWORD

UInt32

18.

BCD integral data type

(Decimal)

BCD8

UInt16

Numerical value notation in BCD as one decimal per 4 bits is described by the ValueAsText Attribute.

Example: Set the ValueAsText Attribute to "58" in BYTE or "0058" in WORD for the value "58".

19.

BCD16

UInt16

20.

BCD32

UInt32

21.

BCDx

(x = 4,12)

UInt16

22.

Real data type

(Decimal)

REAL

Float

-

23.

LREAL

Double

-

24.

String type

STRING(x)

("x" shows an integer from 1 to 2048.)

String

-

25.

STRING_U(x)

("x" shows an integer from 1 to 2048.)

String

or

LocalizedText

As the String DataType for OPC UA is in Unicode, mapping from STRING_U (x) data type in the CSP+ for machine is available. When a locale ID (e.g. "en-US") needs to be specified, the mapping should be conducted to the LocalizedText DataType.

26.

Time type

TIME

Int32

Use EngineeringUnits Property of the variable to specify a unit "ms" and use ValueAsText Attribute to describe a preset notation such as "T#3d11h45m15s123ms".

27.

Date type

DATE

DateTime

-

28.

Accuracy type

ACCURACY

Double

-

29.

IP address type

IP_V4

String

Describe the value in a string.

30.

IP_V4_64

String

Describe the value in a string.

31.

Aggregation type

Data type + "()"

[Example] INT8(),

STRING(10)()

-

As this document does not specify any rules to the CSP+ for machine element having this data type, no DataType mapping rules are specified.

32.

Array type

Data type +"["Number of elements +"]"

-

The OPC UA describes the array by the variable ValueRank Attribute (Number of array dimensions) and ArrayDimensions Attribute (Number of elements for each dimension).
