OPC UA Data Types Mapped to CIMPLICITY Data Types

Data Mapping Notes

• Array Support

1. Only one-dimensional arrays are supported.
2. It is recommended to map OPC UA arrays to CIMPLICITY data types with the Elements property equal to the UA array size.

Note: The number of elements in a CIMPLICITY array point can be selected on the Point Properties dialog box>General tab>Elements field.

• If array elements are configured as not equal (or, if later, a UA variable array size is changed by the UA Server), then, by default, reading these points will fail.
• It is possible to allow a mismatch between a UA array size and CIMPLICITY point Elements, for the device level configuration; the property Allow Array Size Mismatch should be set to True.

Note: Even in this case the CIMPLICITY point Elements cannot be less than the UA Variable array size; truncation is not allowed.

1. It is possible to write to the range of array elements via CimScript API.
2. Scalar OPC UA types must be mapped to CIMPLICITY data types with number of Elements = 1

• 3D_BCD and 4D_BCD Types

3D_BCD and 4D_BCD types are not supported.
