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 features:
- Powerful processor:
The CPU achieves command execution times as low as 0.018 µs per binary instruction. - 32 MB work memory (of which 16 MB each for program and data);
faster work memory for sections of the user program that are significant for execution. - Flexible expansion capability:
Up to 262 144 digital inputs/outputs and 16 384 analog inputs/outputs - MPI multi-point interface:
With the MPI it is possible to establish simple networking of max. 32 stations at a data transmission rate of up to 12 Mbps. The CPU can establish up to 44 connections to stations of the communication 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 connectors to the MPI interface:- With socket: 6ES7 972-0BB42-0XA0
- Without socket: 6ES7 972-0BA42-0XA0
- Mode selector switch:
Toggle switch design. - Diagnostic buffer:
The last 120 fault and interrupt events are retained in a ring buffer for diagnostic purposes (expandable). - Real-time clock:
Diagnostic alarms of the CPU are tagged with the date and time. - Memory card:
For expanding 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 according to EN 50170.
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 972-0BB42-0XA0
- Without socket: 6ES7 972-0BA42-0XA0
- Two additional slots:
Two additional PROFIBUS DP master systems can be connected via IF 964-DP interface modules.
Function
- Block protection:
A password concept protects the user program from unauthorized access. - Integrated HMI services:
For HMI devices, the user only has to specify the source and destination for the data. They are then automatically transported by the system on a cyclic basis. - Integrated communication functions:
- PG/OP communication
- Global data communication
- S7 basic communication
- S7 communication
Parameterizable properties
Using the STEP 7 hardware configuration tool, properties and responses of the S7-400 including the CPUs can be parameterized, e.g.:
- Multi-point interface MPI:
- Determination of node addresses
- Start-up/cyclic response
- Determination of maximum cycle time and communication load
- Address assignment:
Addressing of I/O modules - Retentive areas:
Determination of 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:
Specifying the access rights to programs and data - System diagnostics:
Determination of handling and scope of diagnostic messages - Cyclic interrupts:
Setting of periodicity - Configuration
Display and information functions
- Status and fault displays:
LEDs indicate, for example, internal and external errors and operating states such as RUN, STOP, start-up and test functions. - Test functions:
The PG is used to indicate signal states during program execution, to modify process tags independently of the user program, to output the contents of stack memories, to execute individual program steps, and to block program sections. - Information functions:
The PG can be used to obtain information about the memory capacity and operating mode of the CPU and the current loading of the work and load memory.
