TRICONEX 3501E
Product Name
TRICONEX 2755 Modbus Plus Communication Module; TMR Safety System Interface for Modbus Plus Network Integration (TRICONEX by Schneider Electric Process Safety).
Product Description
The TRICONEX 2755 is a dedicated Modbus Plus communication module engineered for TRICONEX TMR safety instrumented systems, widely used in high-risk industrial applications such as oil & gas refining, chemical processing, power generation, and petrochemical plants. It enables seamless, redundant data exchange between the TRICONEX safety controller and external devices (e.g., PLCs, HMIs, SCADA systems, and third-party controllers) over the Modbus Plus network, supporting both master and slave modes for flexible system integration.
Built to meet IEC 61508 SIL 3 and TÜV safety certifications, the module leverages TRICONEX’s TMR architecture to ensure fault tolerance and eliminate single points of failure—critical for maintaining system integrity in safety-critical processes. Key features include dual independent Modbus Plus ports for redundant network connectivity, hot-swappable design for maintenance without system shutdown, and support for real-time data transmission of process variables, diagnostic information, and control commands.
The TRICONEX 2755 is compatible with TRICONEX 3000, 4000, and 5000 series safety controllers, providing a reliable communication bridge between the safety layer and the plant’s supervisory control layer. It supports a wide range of data transfer rates and network topologies, making it suitable for both small-scale and large-scale industrial installations where safety, reliability, and data integrity are paramount.

Critical Notes (Avoid Common Mistakes)
- Safety System Compatibility: The TRICONEX 2755 is exclusively designed for TRICONEX TMR safety controllers. Do not use it with non-TRICONEX PLC/DCS systems.
- Redundancy Configuration: To achieve full network redundancy, connect both Modbus Plus ports to separate network segments; configure master/slave modes via TRICONEX TriStation software.
- Hot-Swap Operation: Follow TRICONEX safety procedures for hot-swapping the module—ensure the chassis is powered and the module is properly seated to avoid communication disruptions.
- Firmware Matching: Ensure the module firmware version is compatible with the TMR controller firmware; mismatched versions may cause communication failures or system faults.
