FAQ

Q1: What is the primary function of the 6ES7516-3FN02-0AB0?

A: It is a fail-safe CPU for the SIMATIC S7-1500F platform. It handles both standard automation logic and safety-related functions up to SIL 3 / PL e, making it ideal for applications requiring integrated safety without separate hardware.

Q2: Is this product still available?

A: This model has entered the Phase Out (PM400) stage as of October 1, 2024. It remains supported for existing installations, but availability depends on remaining stock. The successor model 6ES7516-3FP03-0AB0 is recommended for new projects.

Q3: What are the memory specifications?

A: The CPU provides 1.5 MB work memory for program and 5 MB work memory for data. A SIMATIC Memory Card (max. 32 GB) is required for load memory and is not included.

Q4: What communication interfaces does this CPU have?

A: It features three interfaces: 1× PROFINET IRT with 2-port switch, 1× PROFINET RT, and 1× PROFIBUS DP master.

Q5: Does this CPU support safety functions?

A: Yes. It is certified to SIL 3 (IEC 61508) and PL e (ISO 13849-1). Standard and safety programs run simultaneously on the same CPU using PROFIsafe communication.

Q6: What software is required for programming?

A: Configuration and programming require TIA Portal V16 or higher. For firmware V2.9, TIA Portal V17 or higher is recommended. For safety programming, an additional Safety Advanced license is required.

Q7: What is the difference between this CPU and the successor 6ES7516-3FP03-0AB0?

A: The successor model offers 3 MB program memory (vs. 1.5 MB), 7.5 MB data memory (vs. 5 MB), and 6 ns bit performance (vs. 10 ns), providing significantly enhanced processing power and memory capacity.

Q8: What is the power supply requirement?

A: The CPU operates on 24 V DC with a permissible range of 19.2 to 28.8 V DC. It includes reverse polarity protection.

Q9: Does this CPU support motion control?

A: Yes. It supports isochronous mode and IRT for high-precision motion control applications, with minimum update times of 250 µs for IRT.

Q10: What is the operating temperature range?

A: The CPU operates from -25°C to +60°C for horizontal installation.
