Transaction Identifier: Identifier Length 128-bit minimum

Component Specifications

Definition

The Transaction Identifier is an electronic or software-based component within industrial redo handler systems that generates, assigns, and manages unique identification codes for manufacturing transactions. It ensures each operational sequence (such as batch processing, assembly steps, or quality checks) can be precisely tracked, logged, and recovered in case of system interruptions or errors. This component maintains synchronization between physical operations and digital records in automated production environments.

Working Principle

Operates by generating sequential or hash-based unique identifiers when a transaction is initiated in the control system. These identifiers are stored in non-volatile memory and associated with timestamp, machine state, and operational parameters. During error conditions, the redo handler uses these identifiers to locate the last verified transaction point and restore system continuity.

Materials

Typically consists of: Microcontroller unit (ARM Cortex-M series or equivalent), Non-volatile memory (EEPROM or FRAM), Communication interface chips (RS-485, Ethernet PHY), PCB with industrial-grade substrates (FR-4 with conformal coating), Stainless steel or aluminum housing (IP65 rated).
