Product Description:

The Siemens SIPLUS S7-1500 CPU 1518-4 PN/DP delivers maximum control performance for complex automation tasks in demanding industrial environments. Based on the standard SIMATIC S7-1500 CPU 1518-4 PN/DP (6ES7518-4AP00-0AB0), this SIPLUS variant features conformal coating for reliable operation under extended temperature ranges from 0 °C to +60 °C, protecting against humidity, dust, and corrosive atmospheres.

Equipped with 4 MB of work memory for programs and 20 MB for data, this CPU provides exceptional capacity for large-scale process, motion, and production automation systems. With an ultra-fast 1 ns bit processing speed, it ensures high-precision, deterministic performance for advanced control applications.

Four integrated communication interfaces — two PROFINET IRT ports with a 2-port switch, one additional Ethernet port, and one PROFIBUS interface — enable flexible connectivity for complex, distributed automation networks. A SIMATIC Memory Card is required for program storage, firmware updates, and secure data handling.

Designed for applications requiring top-tier performance and reliability, the SIPLUS CPU 1518-4 PN/DP is ideal for manufacturing, energy, and process industries operating in challenging environmental conditions.
