Emerson has announced the new PACSystems™ RX3i CPS400 Safety Controller, designed to enable Safety Integrity Level 2 (SIL2) strategies for emergency shutdown systems. The PACSystems Safety Controller is a compact, high-performance solution with robust security measures and a scalable architecture with 2,000 available I/O points, ideal for complex projects with evolving requirements. As project automation becomes more sophisticated and data-driven, OEMs and systems integrators need a range of more powerful hardware and software products to ensure compliance with standards and regulations for protecting workers, whether onboard a single piece of equipment or distributed throughout a much larger process.
Versatile protocol options
A large 64-megabyte memory capacity and scalable digital architecture enables the PACSystems Safety Controller to support a diverse range of mission-critical applications. Using built-in industrial communications protocols, including OPC UA, Ethernet Global Data (EGD), and Modbus TCP, the RX3i CPS400 controller is ready to connect peer-to-peer and with higher level hosts, providing complete operational visibility. As a secure-by-design solution incorporating Secure Boot® and the Trusted Platform Module (TPM) standard, the new controller delivers rigorous data integrity and protection against potential threats. Safety-certified function blocks and pre-configured templates simplify overall system certification in accordance with the IEC 61511 standard.
IEC 61508 certification
Available in simplex or redundant controller configurations, the RX3i CPS400 controller can perform all safety data messaging with duplex communications using the black channel principle over EGD, allowing standardized and reliable connectivity with Emerson’s PACSystems VersaMax™ SafetyNet I/O system. The platform is IEC 61508 safety-certified, providing a capable SIL2 simplified solution to help designers build appropriate protection schemes.
Developers can configure the new controller using familiar software tools employed for programmable logic controllers (PLC), operator interfaces, and other automation elements, namely Emerson’s PAC Machine Edition development environment. As a unified tool chain with a userfriendly interface, the PAC Machine Edition suite streamlines development efforts so users can easily create complete and integrated automation, visualization and safety solutions for rapid startups and maximum operating efficiency.
