application
The CPU 412-3H can be used with SIMATIC S7-400H and S7-400 F/FH. It enables the creation of fault-tolerant S7-400H systems. It can also be used in conjunction with the F runtime license for the S7-400F/FH fail-safe automation system. The built-in PROFIBUS-DP interface enables it to be directly connected to the PROFIBUS-DP fieldbus as a master station.


design
The CPU 412-5H has:

Powerful Processor:
The CPU processes each binary instruction in less than 31.25 ns.
1 MB RAM (512 KB for program, 512 KB for data);
load memory for storing user program and parameter setting data of the S7-400H F/FH automation system; high-speed RAM for sequence-related parts of the user program
Memory card:
used to expand the built-in load memory. In addition to the program itself, the information contained in the load memory also includes the configuration data of the S7-400H F/FH, which is why it takes up double the space in the memory. the result is:
The built-in load memory cannot meet the requirements of large program volumes, so a memory card is required.
RAM and FEPROM cards are provided (FEPROM is used to save data when power is removed).
Flexible expansion options:
up to 131,072 digital and 81,932 analog inputs/outputs.
Combined MPI/PROFIBUS DP interface:
MPI can be used to establish a simple network of 32 nodes with a data transmission rate of 187.5 Kbit/s. The CPU can establish up to 64 connections to nodes on the communication bus (C-bus) and to nodes on MPI.
The PROFIBUS-DP master interface can be used to build a high-speed distributed automation system and greatly simplify operations. To the user, distributed I/O is handled as centralized I/O (same configuration, addressing and programming).
PROFIBUS DP interface:
Through the PROFIBUS DP interface, redundant and distributed automation configuration can be achieved, thereby improving speed and ease of use. To the user, distributed I/O is handled as centralized I/O (same configuration, addressing and programming).
PROFINET interface with 2 ports (switch):
supports system redundancy and MRP (Media Redundancy Protocol)
Mode selection switch:
toggle switch design.
Diagnostic buffer:
The last 120 alarm and interrupt events are saved in a ring buffer and are used for diagnostics.
Real-time clock:
The CPU provides a diagnostic report with date and time.

Function
Block protection:
In addition to locking the switch with a key, illegal access to the user program can also be protected by means of a password.
Integrated HMI services:
For HMI devices, users only need to specify the data source and data target. The data will be transferred automatically and cyclically by the program.
Integrated communication functions:
PG/OP Communication
Extended communication (simple and fault-tolerant)
Parameterizable properties
Through the tool "Hardware Configuration" of STEP 7 and the installed option package S7-400H, the characteristics and behavior of the S7-400H including the CPU can be parameterized, for example:

Multipoint Interface (MPI):
Define the node address.
Start/loop behavior.
Define the maximum cycle time and communication load.
Address assignment:
Addressing of I/O modules.
Retention area:
Defines retentive bit memory, counters, timers and clock memory.
Protection level:
Defines program and data access authorization.
System diagnosis:
Define the processing and scope of diagnostic messages.
Monitor interrupt:
Set period.
Configure the H station.
Security related features
With the F runtime license, safety-related F user programs can be compiled and run on the CPU. 1 license is required per S7-400F/FH system. The scope of delivery includes 2 2 TÜV (German Technical Supervision Agreement) labels.

Display function and information function
Status and fault indicators:
LEDs indicate internal and external faults and operating states such as RUN, STOP, commissioning, "Master" operating mode, redundancy faults and test functions.
Test functions:
You can use the programming device to display signal states during program execution, modify process variables regardless of the user program, output the contents of the stack memory, run individual program steps and disable program components.
Information functions:
The user can obtain information on the memory capacity and operating mode of the CPU as well as the current utilization of RAM and load memory.
