SIMATIC S7-1500F 6ES7517-3FP00-0AB0 CPU 1517F-3 PN DP PLC Module

Product Introduce

6ES7517-3FP00-0AB0 is a fail-safe central processor of the SIMATIC S7-1500F series. The IRT interface meets isochronous real-time communication, 2 ns instruction execution speed, supports distributed/centralized isochronous mode (minimum OB 6x cycle for distributed 250 μs, centralized 1 ms), and is suitable for high-speed control tasks.

FAQ:

1.When using 6ES7517-3FP00-0AB0 with an SMC card, which capacity and type of memory card should be selected?

1. Type: Siemens original SIMATIC MC (Micro SD, 6ES7954 series), does not support third-party cards
2. Capacity: 4MB-32GB (maximum 32GB)
3. Recommended capacity: basic projects ≥24MB, fail-safe/complex projects ≥256MB/2GB, firmware ≥V2.9.2 requires ≥256MB
4. Commonly used models: 6ES7954-8LC04-0AA0 (24MB), 6ES7954-8LL04-0AA0 (256MB), 6ES7954-8LP04-0AA0 (2GB)

2.When the PROFIBUS interface serves as a DP master/slave station, what is the maximum number of slave stations supported by 6ES7517-3FP00-0AB0?

The PROFIBUS DP interface of 6ES7517-3FP00-0AB0 (CPU 1517F-3 PN/DP) only supports DP master stations and does not support DP slave stations.

1. Maximum number of DP slave stations: 125 (PROFIBUS address 0–125, master station occupies 1 address)
2. A single network segment (without repeater) has a maximum of 32 sites (including master station, repeater, etc.), which needs to be expanded to 125 slave stations through repeaters; limited by the PROFIBUS protocol, the entire DP network has a maximum of 126 sites (master station + 125 slave stations)
3. Supplement: The maximum number of S7 communication connections for the DP interface is 48, which is two independent indicators from the number of DP slave stations.

3.What are the functional differences and compatibility of the 6ES7517-3FP00-0AB0 with non-fail-safe CPUs of the same series (e.g. CPU 1517-3 PN/DP)?
