NEW 6ES7151-8AB01-0AB0

Basic Information

• Product Type Designation: IM 151-8 PN/DP CPU, functioning as both an interface module and a compact CPU for the ET 200SP distributed I/O system.
• Role: Acts as a PROFINET IO controller and PROFIBUS DP master, enabling connection of ET 200SP I/O modules while managing communication with higher-level systems or other field devices.
• Hardware Functional Status: From FS03 onwards.
• Firmware Version: Upgradable to support new features and improvements.

Processing and Memory

• Processor Performance: Equipped with a 32-bit microprocessor, supporting instruction execution times as low as 0.1 µs for basic operations.
• Memory: Includes 150 KB of work memory for program (load memory) and 100 KB for data, with an external memory card slot (MMC) supporting up to 32 GB for program storage and data logging.

Communication Capabilities

• PROFINET Interface: 2-port switch (10/100 Mbps) supporting PROFINET IO controller, IO device, and open IE communication (TCP/IP, UDP). Features include isochronous real-time (IRT), PROFINET CBA, and media redundancy protocol (MRP).
• PROFIBUS DP Interface: Supports PROFIBUS DP master operation with a transmission rate of up to 12 Mbps, capable of connecting up to 125 DP slaves.
• Other Communication: Integrated web server for diagnostics and configuration; supports S7 communication, OPC UA, and MODBUS TCP (client/server) via blocks.

I/O Capabilities

• Local I/O: Can control up to 64 ET 200SP I/O modules (distributed across the ET 200SP station), supporting digital, analog, and specialty modules.
• Process Data: Maximum process data length of 2048 bytes (input) and 2048 bytes (output).

Programming and Configuration

• Programming Environment: Supported by STEP 7 TIA Portal (from version V13) using SIMATIC S7-1200 instruction set, including LAD, FBD, STL, and SCL (Structured Control Language).
• Function Blocks: Includes a comprehensive library of standard and technology-specific function blocks for motion control, process control, and communication.

Diagnostic and Security Features

• Diagnostics: Extensive diagnostic capabilities with detailed error messages, accessible via TIA Portal, web server, or HMI devices. Supports module-level and channel-level diagnostics for connected I/O.
• Security: Includes password protection for program access, and supports PROFINET security mechanisms (e.g., Secure Communication) to prevent unauthorized access.

Mechanical and Environmental Specifications

• Dimensions: 30 mm width, 125 mm height, 90 mm depth (including connectors).
• Weight: Approximately 250 g.
• Power Supply: Requires 24V DC (19.2V to 28.8V) with a typical current consumption of 300 mA.
• Operating Temperature: -25°C to +60°C.
• Mounting Altitude: Up to 5000 m, with derating for temperatures above 40°C at altitudes exceeding 2000 m.
• Protection Rating: IP20 when mounted in a suitable enclosure.
• EMC Compliance: Meets IEC 61131-2, EN 61000-6-2 (industrial environment), and other relevant standards for electromagnetic compatibility.
