Specifications Parameter Specification Manufacturer / Series Schneider Electric / Modicon Premium (Telefast & Associated Products) Reference / Part Number STBNDP2212 Alternative/Previous Ref. STBNDP2210 (First generation) Product Type Hot Standby Communication Coprocessor (Dual-Port, Gen 2) Compatible CPUs Modicon Premium TSX P57 系列 and TSX P57 68M series CPUs (must be used in pairs). Redundancy Mode Hot Standby (1:1 redundancy) Synchronization Link Dedicated point-to-point link between the two coprocessors. Synchronization Media Fiber-optic cable (standard, for electrical isolation and long distance). May also support specialized twisted-pair cable in certain configurations. Maximum Link Distance Up to 1 km with multi-mode fiber (62.5/125 µm). Distance depends on fiber type. Synchronization Time Very fast; typical update times in the range of tens of milliseconds, ensuring minimal data lag between CPUs. Switchover Time Typically < 1 second (from fault detection to standby CPU taking full control), ensuring a "bumpless" transfer for most continuous processes. Data Synchronized Full application program, system configuration, I/O image tables, and specific data tables defined by the programmer. Module Power Supply Powered directly from the Premium rack backplane (+5 VDC). Diagnostics Comprehensive LED indicators on the front panel for status, link activity, errors, and primary/standby role. Operating Temperature 0°C to +60°C (32°F to 140°F) Storage Temperature -40°C to +85°C Relative Humidity 5% to 95% (non-condensing) Vibration/Shock Designed for industrial environments per relevant IEC standards. Standards & Certifications CE, UL, cUL, etc., as part of the Premium system.
