Product Core Basic Information and Positioning

Basic identification and functional positioning

Specific project content

Ordering Number 6DD1607-0AA2 (core ordering identifier, belonging to the FM458-1 DP application module of SIMATIC S7-400 series)

Product series SIMATIC S7-400 (Siemens high-end PLC series, suitable for complex industrial control requirements)

Module type FM458-1 DP Application Module (dedicated application module, supports PROFIBUS DP communication, can achieve high-precision and high real-time control tasks)

Complex control tasks in typical application scenarios of industrial automation, such as process control, motion control, synchronous control, etc., require data exchange with other devices (such as I/O modules, drivers) through the PROFIBUS DP bus

Key electrical and hardware parameters

1. Power supply characteristics

The stability of power supply directly affects the reliability of module operation. The document clearly indicates the requirements for dual voltage power supply and the range of current consumption:

Specific specifications of power supply parameters

Rated supply voltage -5V DC (core logic power supply);

-24V DC (auxiliary power supply, such as digital input circuit)

The allowable voltage range is 5V DC: 4.8V~5.25V (including ripple), ensuring that voltage fluctuations do not affect the core functions of the module; 24V DC does not specify the specific fluctuation range, please refer to the overall power supply specification of S7-400 system

Input current - typical consumption: 1.5A;

-Maximum consumption: 3A (to ensure that the system power capacity meets the requirements and avoid overload)

2. Storage and clock function

The module has data backup and real-time clock functions, supporting time correlation and data persistence of control tasks:

Specific specifications for functional categories

Storage backup - equipped with SRAM (Static Random Access Memory), supporting data backup;

-Backup battery: An external backup battery is required, with a maximum backup current of 15 μ A (low-power design to extend battery life)

Real Time Clock - Hardware Clock: Equipped with;

-Resolution: 500ms (can meet the time synchronization requirements of most industrial control scenarios)

3. Digital input interface

Provide 8 digital inputs for receiving external switch signals (such as sensor and button signals), with parameters adapted to industrial standard signals:

Specific specifications of digital input parameters

Input quantity of 8 channels, interface is Connector X2 (dedicated wiring terminal, corresponding cable needs to be matched)

Rated input voltage 24V DC (commonly used industrial DC signal voltage, compatible with most sensor outputs)

Signal logic - signal "0" (off): -1V~+6V;

-Signal "1" (conducting): 13.5V~33V (wide range design, strong resistance to voltage fluctuations)

Input current - signal "0" maximum static current: 0mA (no leakage current, to avoid false triggering);

-Typical current of signal "1": 3mA (at 24V DC, low power consumption, reducing total system energy consumption)

Response time "0" → "1" (conduction) Maximum delay: 5 μ s (high-speed response, adapted to rapidly changing on-site signals)

Potential isolation does not have built-in potential isolation (Potential Separation: No), and isolation needs to be achieved through optional interface modules to avoid on-site interference entering the module's interior

Communication and functional characteristics

1. PROFIBUS DP interface (core communication function)

As a key feature of the FM458-1 DP module, the PROFIBUS DP interface supports high real-time and high reliability industrial bus communication:

Specific specifications of communication parameters

Equidistance support and connection to Interrupt Tasks ensure stable time intervals for data transmission, meeting high-precision requirements such as synchronous control

Slave to Slave Communication support for direct data exchange between stations, without the need for forwarding through the main station, reducing data transmission latency and improving system response speed

2. Interruption and Diagnosis

The module has alarm and status feedback functions, which facilitate troubleshooting and system maintenance:

Alarm function: Supports sending fault alarm signals (such as module failures or communication abnormalities) to the PLC master station or upper computer through the PROFIBUS DP bus;

Diagnostic/Status Information: Provides module operation status information (such as power supply status, communication status) to assist technicians in quickly locating problems.

Physical and installation parameters

Specific specifications of physical parameters

Weight approximately 1000g (1kg, lightweight design, compatible with S7-400 base plate installation, no additional load-bearing burden)

Slot requirements require one slot on the S7-400 motherboard (Required Slot: 1), and installation must follow the motherboard slot numbering rules without special slot restrictions
