Function

High availability design: Specifically designed for S7-400H redundant systems, it supports hot backup and failover to ensure zero system downtime.

High-performance processing: With a 12MB large-capacity memory, it can quickly handle complex logic and large-scale data, making it suitable for high-performance control tasks.

Multi-interface communication

The MPI/DP interface supports multi-point communication and distributed I/O control, with a transmission rate as high as 12 Mbit/s.

The PROFIBUS DP interface connects distributed devices, such as sensors, actuators or Hmis.

The two synchronization module interfaces support the dual-CPU synchronous operation of the S7-400H system.

Diagnostic function: Real-time monitoring of system status through LED indications (INTF, EXTF, BUS1F, BUS2F, FRCE, RUN, STOP) simplifies fault detection.

Flexible expansion: Supports up to 21 expansion units, with a maximum of 65,536 digital channels and 4,096 analog channels, suitable for large-scale systems.

Programming support: Compatible with the STEP7 programming environment, supports multiple programming languages (such as LAD, FBD, STL), and supports CiR (Configuration in Motion) to reduce downtime.

Application scenarios

Energy industry

Power plant: It is used in thermal, nuclear or wind power systems to control key equipment (such as turbines, generators), ensuring high availability and safety.

Substation: Manage the high-voltage distribution system and ensure uninterrupted operation through redundant design.

Oil and gas processing: Applied in oil refineries or natural gas processing stations to handle complex process control tasks.

High availability industrial scenarios: Used in scenarios requiring zero downtime, such as steel mills, chemical production or mining, to ensure the continuous operation of the system.

Distributed control system: Through the PROFIBUS DP interface, it is suitable for remote monitoring and distributed I/O control, such as large-scale energy infrastructure.
