CPU 414–5H 是用于 SIMATIC S7-400H 和 S7-400 F/FH 的 CPU。它允许配置为一个容错的 S7-400H 系统。它可与 F 运行授权一起用于故障安全 S7-400®F/FH 自动化系统。内置的PROFIBUS-DP接口使它能够作为主站或从站直接连接到PROFIBUS-DP现场总线。

• Block protection: 
  A password concept also protects the user program from unauthorized access as well as the keyswitch.
• Integrated HMI services: 
  The user only has to specify the source and destination of the data with HMI devices. The data are then transported cyclically and automatically by the system.
• Integrated communication functions:
  • PG/OP communication
  • Expanded communication (simple and high-availability)

Configurable Attributes

The STEP 7 "hardware configuration" tool and the installed S7-400H options package are used to configure the features and response of the S7-400H, including the CPUs, for example:

• Multipoint interface MPI:
  • Definition of node addresses
  • Startup/cycle behavior
  • Stipulation of the maximum cycle time and communication load
• Address allocation: 
  Addressing of I/O modules
• Retentive area: 
  Definition of the number of retentive bit memories, counters, timers, data blocks, and clock memories
• Protection level: 
  Definition of access authorizations to program and data
• System diagnostics: 
  Definition of the handling and scope of diagnostics messages
• Timed interrupts: 
  Setting of periods
• Configuration of H stations

Safety-related functions

The F-runtime license can be used to compile the failsafe F user program and run it on the CPU. A license is required for each S7-400F/FH system. 2 TÜV stickers are included.

Reporting functions

• Status and fault indicators: 
  LEDs indicate internal and external errors and operating modes such as RUN, STOP, Startup, "Master” mode, redundancy error, test function, etc.
• Test functions: 
  The PG can be used to display signal states in program execution, modify process tags irrespective of the user program, read out the contents of stack memories, run separate program steps and inhibit program components.
• Information functions: 
  The PG can be used to provide the user with information about the memory capacity and operating mode of the CPU, and the current utilization of the working and load memories.
