SIPLUS CPU 414H производства Siemens

The CPU 414-4H is compatible with the SIMATIC S7-400H and S7-400F/FH. It allows a fault-tolerant S7-400H system to be configured. It can also be used for the failsafe S7-400F/FH automation system in conjunction with an F-runtime license. The integrated PROFIBUS DP interface supports direct connection to the PROFIBUS DP fieldbus as master.

The CPU 414-4H features:

• A powerful processor:
  The CPU achieves command runtimes as little as 45 ns per binary command.
• 2.8 MB main memory (1.4 MB for programs, 1.4 MB for data);
  load memory for user programs and configuration data for the S7-400H F/FH automation system; fast main memory for subroutines of the user program that are relevant to the process
• A memory card:
  For extending the integrated load memory. In addition to the program itself, the information contained in the load memory also includes configuration data for the S7-400H F/FH, which is why it takes up twice as much space in the memory. The result is that:
  • The integrated load memory is not sufficient for large programs, which is why the memory card is often required.
    RAM and FEPROM cards are available (FEPROM for saving even when not connected to the power supply).
• Easy removal:
  Max. 65K digital and 4K analog inputs/outputs.
• Multipoint-capable MPI interface:
  The MPI enables the creation of a simple network with max. 32 nodes and a data transfer rate of 187.5 Kbit/s. The CPU can establish up to 64 connections to users of the communication bus (C bus) and the MPI.
  Note:
  If PROFIBUS DP and MPI interfaces are being used simultaneously, only the following bus connectors can be connected to the MPI interface:
  • With socket: 6ES7 972-0BB41-0XA0
  • Without socket: 6ES7 972-0BA41-0XA0
• Mode selector:
  Designed as a toggle switch.
• Diagnostic buffer:
  The last 120 alarm and interrupt events are stored in a ring buffer for the purpose of diagnosis.
• Real-time clock:
  Diagnostic reports from the CPU are provided with the date and time.
• PROFIBUS DP interface:
  The CPU 414-4H with PROFIBUS DP master interface enables distributed automation to be established at high speed and with easy operation. From the user's point of view, the distributed peripherals are treated like centralized peripherals (same configuration, addressing and programming).
  Note:
  If PROFIBUS DP and MPI interfaces are being used simultaneously, only the following bus connectors can be connected to the MPI interface:
  • With socket: 6ES7 972-0BB41-0XA0
  • Without socket: 6ES7 972-0BA41-0XA0

• 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.
