Detailed Description

Unit tests for PROFINET DCE/RPC helpers and connection configuration.

Verifies UUID conversion, EPM endpoint identification, IOCR setup validation, RPC header construction, and IOCR block generation provided by rpc.h.

The tests cover:

• Conversion between UUID byte arrays and canonical UUID strings.
• Rejection of malformed UUID strings.
• Recognition of well-known PROFINET EPM interface UUIDs.
• Case-insensitive EPM interface UUID matching.
• Formatting of unknown EPM interface UUIDs.
• IOCR cycle-time calculation from send-clock factor and reduction ratio.
• Validation warnings for missing I/O slots and insufficient watchdog factors.
• Acceptance of a normal IOCR configuration.
• Construction of PNRPCHeader requests with the expected DCE/RPC fields.
• Verification of the PROFINET device interface UUID wire representation.
• Construction of IOCR blocks from configured I/O slots.
• Verification of IOCR type, data length, and API object counts.

The tests focus on deterministic protocol construction and configuration behavior without requiring a live PROFINET device or network connection.
