MODBUS SLAVE COMMUNICATION FUNCTION

The Modbus slave communication function enhances ProSafe-RS by enabling seamless interaction with external control systems. This feature allows a Safety Control Station (SCS) to operate as a Modbus slave device, establishing standardized communication with third-party Modbus master systems. The architecture supports real-time data exchange while maintaining ProSafe-RS's safety integrity, creating a bridge between the safety system and external PLCs/DCS without compromising reliability.

Key benefits include bi-directional data transfer of process values and diagnostics, simplified system integration, and preserved safety functionality. Typical applications involve integrating safety alarms or process shutdown signals with plant-wide control systems, enabling centralized monitoring while keeping safety logic independent. The implementation maintains ProSafe-RS's certifications (including IEC 61508 SIL3) while adding Modbus RTU/TCP protocol support.
