Siemens 6ES7517-3FP00-0AB0 CPU Module for SIMATIC S7-1500

Siemens 6ES7517-3FP00-0AB0 is a SIMATIC S7-1500F CPU module (1517F-3 PN/DP) that serves as the central processing unit for safety-enabled automation. It provides 3 MB of program memory and 8 MB of data memory, and offers three communication interfaces: PROFINET IRT with a built-in 2-port switch, PROFINET RT, and PROFIBUS, delivering deterministic bit timing with 2 ns resolution. A SIMATIC Memory Card is required for program and data storage. The module supports distributed and centralized configurations, with a minimum OB cycle of 250 µs in distributed mode (six OBs) and 1 ms in centralized mode, enabling isochronous, synchronized control for high-speed machinery and networked devices. This CPU is part of the SIMATIC S7-1500 family and is well-suited to safety-related applications that demand fast PROFINET IRT/RT connectivity along with PROFIBUS compatibility for legacy peripherals.
