Область применения

The CPU 414F-3 PN/DP is a CPU for high demands in the mid-level performance range. They meet higher demands for program scope and instruction processing speed. It permits the design of a fail-safe automation system for plants with increased safety requirements.

The integrated PROFIBUS DP interfaces make it possible to connect directly to the PROFIBUS DP fieldbus as a master or slave.

An additional DP master system can be connected via the IF 964-DP interface module.

For the PROFINET interface of the CPU 414F-3 PN/DP, the switch functionality permits the formation of two externally accessible PROFINET ports. In addition to hierarchical network topologies, this also enables the creation of line structures in the new S7-400 controllers.

Note:
Only interface module 6ES7964-2AA04-0AB0 can be used.

Дизайн

The CPU 414-3 PN/DP is equipped with the following:

Powerful processor:
The CPU achieves command execution times as low as 0.045 µs per binary instruction.
4 MB RAM (of which 2 MB each for program and data);
fast RAM for parts of the user program relevant to execution.
Flexible expansion:
Up to 131072 digital and 81932 analog inputs/outputs.
Multi-point interface MPI:
With the MPI it is possible to establish simple networking of max. 32 stations at a data transmission rate of up to 12 Mbit/s. The CPUs can establish up to 32 connections to stations of the communication bus (C bus) and the MPI.
Mode selector switch:
Designed as toggle switch.
Diagnostics buffer:
The last error and interrupt events are retained in a ring buffer for diagnostic purposes. The number of entries can be parameterized.
Real-time clock:
The date and time are appended to diagnostic messages of the CPUs.
Memory card:
For expansion of the integrated load memory. The information in the load memory comprises S7-400 parameterization data in addition to the program and therefore requires twice as much memory space. The result is:
- The integral load memory for large programs is not sufficient, therefore a memory card is frequently required. RAM and FEPROM cards (FEPROM for retentive storage) are available.
PROFIBUS DP interface and combined MPI/DP interface:
The PROFIBUS DP master interface allows a distributed automation configuration offering high speed and ease of use. From the user's point of view, the distributed I/O is treated as central I/O (same configuring, addressing and programming).
Mixed configuration: SIMATIC S5 and SIMATIC S7 as PROFIBUS master according to EN 50170.
Additional module slot:
An additional PROFIBUS DP master system can be connected via the IF 964-DP interface module.
PROFINET interface with 2 ports (switch):
- PROFINET I/O, 256 IO devices connectable
- PROFINET CBA

Функции

Block protection:
A password concept protects the user program from unauthorized access.
Integrated HMI services:
In the case of HMI devices, the user only has to specify the source and destination of the data. These are automatically transferred cyclically by the system.
Integrated communication functions:
- PG/OP communication
- Global data communication
- S7 basic communication
- S7 communication
Firmware update over the network
Open communication over TCP/IP, UDP and ISO-on-TCP (RFC1006)
Distributed intelligence in Component Based Automation (CBA) on PROFINET
Additional diagnostic option with integrated web server

Parameterizable properties

The STEP 7 tool "Hardware Configuration" can be used to program the properties and response of the S7-400 including the CPUs, e.g.

Multi-point interface MPI:
- Determining station addresses.
- Startup/cyclic behavior.
- Definition of maximum cycle time and communication load.
Address assignment:
Addressing of the I/O modules.
Retentive areas:
Definition of the number of retentive bit memories, counters, timers, data blocks and clock memories.
Size of the process image, local data.
Length of the diagnostic buffer.
Protection level:
Definition of access authorization to program and data.
System diagnostics:
Determination of handling and scope of diagnostics messages.
Cyclic interrupts:
Setting periodicity.
PROFINET interface
Parameterization of time synchronization with NTP procedure

Display and information functions

Status and fault indicators:
LEDs indicate, for example, internal and external errors and operating states such as RUN, STOP, start-up and test functions.
Test Functions:
The programming device can be used to display signal states in the program execution sequence, modify process variables independently of the user program, output contents of stack memories, run through program steps individually, and disable program sections.
Information functions:
The user can obtain information about the memory capacity and operating mode of the CPU, and the current utilization of the RAM and load memory.

Communication

The safety related and standard communication between the central controller and the fail-safe ET 200 modules takes place over PROFIBUS DP and/or PROFINET. The specially developed PROFIBUS profile PROFIsafe allows the transmission of user data associated with the safety function within the standard data telegram. Additional hardware components, e.g. special safety buses, are not required. The necessary software is either integrated into the hardware components as an expansion, or reloaded into the CPU as a certified software block.

Mode of operation

The safety functions of the F-CPU are included in the F program of the CPU and in the fail-safe signal modules.

The signal modules monitor output and input signals by means of discrepancy analyses and test signal injections.

The CPU checks the proper operation of the controller with regular self-tests, command tests, and logical and chronological program execution checks. In addition, the I/O is checked by means of sign-of-life requests.

If a fault is diagnosed in the system, the system is brought to a safe state.

An F-Runtime license is not required to operate the CPU 414F-3 PN/DP.

Programming

The CPU 414F-3 PN/DP is programmed in the same manner as the other SIMATIC S7 systems. The user program for non-fail-safe plant sections is created with the field-proven programming tools, e.g. STEP 7.

Option packages SIMATIC S7 Distributed Safety (Classic) andSIMATIC Safety Advanced V12 (TIA Portal V12)

The STEP 7 option packages "SIMATIC S7 Distributed Safety" (Classic) or SIMATIC Safety Advanced V12 (TIA Portal V12) are required for programming the safety-related program sections. The packages contain all the functions and blocks required to create an F program.

The F program with the safety functions is connected in F FBD or F LAD or using special function blocks from the F library. Use of F FBD or F LAD simplifies configuration and programming of the system and also acceptance testing thanks to the cross-system uniform presentation form. Programmers can concentrate fully on the safety-related application without having to use additional tools.
