Core Functionality

Redundant Safety Computation
Dual or triple processors operate in lockstep with continuous cross-checking. Single-point failures remain within the defined safety boundary and do not compromise safe operation.

Safety Logic & System Control

Execution of safety logic and interlock strategies

Event recording and diagnostic reporting

Deterministic response for safety-critical actions

Communication Expansion
By using the F8627X module, the controller connects to Industrial Ethernet networks and exchanges data reliably with DCS and PLC systems.

Online Maintenance
Hot-swappable design ensures fault isolation and module replacement without interrupting overall system operation.
