Working Principle
The DAP232 operates as a digital application processor within ALSTOM’s control system architecture. It executes application-specific control programs that are loaded into its memory during configuration. The module receives input data from field instruments and other system modules via the backplane bus, processes this data according to the programmed control algorithms, and generates output commands for actuators and other output devices. The processor executes its control tasks in a deterministic manner, ensuring that control actions are taken within specified time constraints. The module communicates with other components in the control system, sharing process data, status information, and diagnostic reports. Built-in self-diagnostics continuously monitor the module’s hardware and software integrity, reporting any faults to the system for operator awareness and maintenance action. In redundant configurations, the DAP232 may operate in parallel with a counterpart module, with automatic switchover in the event of a failure to maintain continuous control.
