Support for the SHORT_STRING (0xDA) data type

Description

As a system integrator, I want parameters in an EtherNet/IP EDS file to support the data type SHORT_STRING (0xDA) so that device configuration can correctly interpret and exchange string-based parameter values according to the EtherNet/IP specification.

Parameters used in EtherNet/IP communication are described within an EDS (Electronic Data Sheet) file, and each parameter must define a corresponding data type. Currently, the SHORT_STRING (0xDA) data type is not yet supported and must be added to ensure full compatibility with device vendors and tools that rely on this specification.

Requirement
The system shall support defining parameters of type SHORT_STRING (0xDA) within an EtherNet/IP EDS file, enabling correct parsing, validation, and runtime handling of these parameter values.

Detailed implementation

• Extend the EDS parser module to recognize the data type identifier 0xDA as SHORT_STRING.
• Ensure backward compatibility with existing data types already supported in the system.

Integration

• Integrate the new data type support into the configuration UI, ensuring that users can view and modify SHORT_STRING parameters.
• Verify compatibility with existing EtherNet/IP stacks.
• Ensure that the runtime communication layer can read and write SHORT_STRING values without data loss.

Acceptance criteria

• Given an EDS file containing a parameter with data type 0xDA, when the system loads the file, then the parameter is correctly recognized as SHORT_STRING.
• When editing the parameter in the UI, the system allows entering and storing a valid SHORT_STRING value.
• Communication tests show that SHORT_STRING values are transmitted and received correctly via EtherNet/IP.
