A0010 Safety Controller
ICSsectorsGeneral
platformsEmbedded
Safety controllers are typically a type of field device used to perform the safety critical function. Safety controllers often support the deployment of custom programs/logic, similar to a PLC, but can also be tailored for sector specific functions/applications. The safety controllers typically utilize redundant hardware and processors to ensure they operate reliably if a component fails.

- Safety Instrumented System (SIS) controller · General
SIS controllers are used to “take the process to a safe state when predetermined conditions are violated” (Citation: Guidance - NIST SP800-82) through the reading of sensor data and interaction with digital/physical control surfaces. These devices are oftentimes located on programmable embedded devices running specialized RTOS or other embedded operating systems.
- Emergency Shutdown Systems (ESD) controller · General
Emergency Shutdown System controllers are used to read sensor values and interact with control surfaces to return the system “to a safe static condition so that any remedial action can be taken”. (Citation: SIGTTO ESD 2021)
- Burner Management Systems (BMS) controller · General
Burner Management System controllers are used to interact with sensors and control surfaces to maintain safe operating conditions for the burner. These can include safely starting-up and managing the main flame, controlling and monitoring the burning conditions, and safely initiating planned or unplanned shutdown sequences.
