Advantages and Key Features

Integrated Fail-Safe S7-1500 Control

The controller comes with the S7-1500 Software Controller CPU 1505SP F preinstalled. It supports standard automation and safety-related control functions, allowing users to consolidate control tasks on an industrial PC platform.

Safety Performance up to SIL 3 and PL e

The CPU 1515SP PC2 F is designed for safety applications up to SIL 3 according to IEC 61508 and Performance Level e according to ISO 13849. The achieved safety level depends on the complete safety system design, selected components, and application validation.

Industrial PC Architecture

An Intel Atom E3940 quad-core processor provides the computing platform for PLC control and compatible PC applications. This architecture is suitable for installations that need both automation processing and higher-level software functions.

Windows 10 IoT Enterprise

The supplied configuration includes Windows 10 IoT Enterprise 64-bit. This provides a familiar environment for compatible industrial applications, data processing, and system integration.

8 GB RAM and CFast Storage

The controller is equipped with 8 GB RAM and a 30 GB CFast card in the specified SIPLUS configuration. The removable CFast storage supports the operating system, runtime environment, and project data.

PROFINET Communication

The ET 200SP platform supports PROFINET connectivity through a compatible BusAdapter. This allows integration with distributed I/O stations, controllers, and other industrial Ethernet equipment.

Expandable ET 200SP Architecture

The controller supports centralized expansion with ET 200SP modules. This provides flexibility when adding digital I/O, analog I/O, communication, and safety-related modules according to the application requirements.

SIPLUS Environmental Protection

Conformal coating and an extended operating temperature range of -40 to +60°C distinguish this SIPLUS model from standard Open Controller versions. Its environmental resistance makes it suitable for demanding industrial installations.

TIA Portal Engineering

The S7-1500 Software Controller F is engineered using STEP 7 in TIA Portal. This supports integration with Siemens automation projects and established programming practices for standard and fail-safe control.

Technical FAQs

Q1: What is the main function of the Siemens 6AG1677-2SB42-2GB0?

A: It is a SIPLUS ET 200SP CPU 1515SP PC2 F Open Controller. It combines an industrial PC platform with the S7-1500 Failsafe Software Controller CPU 1505SP F for standard and safety-related automation tasks.

Q2: What does the F designation mean in CPU 1515SP PC2 F?

A: The F designation identifies the fail-safe version. It indicates support for safety-related automation functions in addition to standard PLC control, when used with compatible fail-safe engineering, I/O, and system components.

Q3: Which safety standards does the controller support?

A: The CPU 1515SP PC2 F is designed for applications up to SIL 3 according to IEC 61508 and PL e according to ISO 13849. The complete safety system must be engineered and validated to achieve the required safety level.

Q4: Which software controller is preinstalled?

A: The specified model comes with the S7-1500 Software Controller CPU 1505SP F preinstalled. It provides the fail-safe PLC runtime for the controller platform.

Q5: Which operating system does the unit use?

A: The supplied configuration includes Windows 10 IoT Enterprise 64-bit. Compatibility with installed applications and engineering tools should be checked before upgrading or modifying the operating environment.

Q6: Which engineering software is required?

A: STEP 7 in TIA Portal is used to configure and program the CPU 1515SP PC2 F. Siemens documentation lists TIA Portal V16 as the starting version for configuration of this CPU generation. The specific software and hardware support package requirements should be checked for the installed firmware.

Q7: Can the controller operate with ET 200SP safety I/O modules?

A: Yes. It can be integrated with compatible ET 200SP fail-safe I/O modules and standard I/O modules. The selected modules and their configuration must match the safety architecture and project requirements.

Q8: How does the controller communicate with distributed I/O?

A: It uses PROFINET through a compatible ET 200SP BusAdapter. The interface supports communication with distributed I/O stations and other PROFINET-capable automation devices.

Q9: What should be checked if the fail-safe controller does not enter RUN mode?

A: Check the 24 VDC supply, startup diagnostics, CFast storage, hardware configuration, firmware compatibility, and fail-safe program status. Also review safety-related diagnostic messages in TIA Portal and confirm that connected F-I/O modules are correctly configured.

Q10: Can the 6AG1677-2SB42-2GB0 replace the standard 6AG1677-2DB42-2GB0?

A: They belong to the same SIPLUS ET 200SP Open Controller family, but they are not functionally identical. The 6AG1677-2SB42-2GB0 is the fail-safe CPU 1515SP PC2 F version, while the 6AG1677-2DB42-2GB0 is the standard CPU 1515SP PC2 version. Replacement requires checking the safety requirements, software configuration, and project compatibility.
