Overview
- 功能強大的 SIMATIC S7-400 CPU
- 可用在高性能范圍中zui復雜的裝置
- 有 2 個 IF 模塊插槽
Area of application
The CPU 417-4 is the most powerful SIMATIC S7-400 CPU. The integral PROFIBUS DP interfaces permit direct connection to the PROFIBUS DP fieldbus as master or slave.
Two further DP master systems can be connected via the IF 964-DP interface submodules.
Note :
Only the interface module 6ES7 964-2AA04-0AB0 can be used.
Design
The CPU 417-4 has:
- Powerful processor:
The CPU achieves instruction execution times as low as 0.018 µs per binary instruction. - 30 MB RAM （of which 15 MB each for program and data）;
fast RAM for parts of the user program relevant to execution. - Flexible expansion:
Up to 262144 digital and 16384 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 CPU can establish up to 44 connections to stations of the communications bus （C bus） and the MPI.
Note:
If the PROFIBUS DP interface and MPI interface are operated simultaneously, it is only possible to connect the following bus connector to the MPI interface:- With socket: 6ES7 972-0BB41-0XA0
- Without socket: 6ES7 972-0BA41-0XA0
- Mode selector switch:
Designed as toggle switch. - Diagnostics buffer:
The last 120 fault and interrupt events are retained in a ring buffer for diagnostic purposes （extendable）. - Real-time clock:
The date and time are appended to diagnostic messages of the CPU. - 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 is not sufficient for large programs, therefore a memory card is frequently required.
RAM and FEPROM cards （FEPROM for retentive storage） are available
- The integral load memory is not sufficient for large programs, therefore a memory card is frequently required.
- PROFIBUS 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 with SIMATIC S7 as PROFIBUS master to EN 50170.
Note:
If the PROFIBUS DP and MPI interface are operated simultaneously, it is only possible to connect the following bus connectors to the MPI interface:- With socket: 6ES7 972-0BB41-0XA0
- Without socket: 6ES7 972-0BA41-0XA0
- Two additional slots:
Two additional PROFIBUS DP master systems can be connected via IF 964-DP interface modules.
Functions
- Block protection:
a password concept also protects the user program from unauthorized access - 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
- Global data communication
- S7 standard communication
- S7 communication
Configurable Attributes
The STEP 7 tool "Hardware configuration" can be used to program the properties and response of the S7-400 including the CPUs, e.g.
- 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 - Size of the process image, local data
- Length of the diagnostics buffer
- 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 - Configuring
Reporting functions
- Status and fault indicators:
LEDs indicate internal and external faults and operating modes such RUN, STOP, restart, 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.
