CPU 1518-4JP00 – high-performance control with integrated safety and redundancy
The Siemens 6AG1518-4JP00-4AB0 is a SIMATIC S7-1500 CPU designed for control applications that demand fast processing and deterministic PROFINET communication. It supports DCP (Discovery and Configuration Protocol) and DNS (Domain Name System) for streamlined IP address assignment and hostname resolution in managed networks per the specification. For media redundancy, the CPU acts as an MRP Automanager according to IEC 62439-2 Edition 2.0, eliminating the need for an external redundancy switch in ring topologies. This reduces hardware count and simplifies network cable routing. Safety applications are handled via PROFIsafe V2.4 / V2.6, enabling fail-safe communication over the same PROFINET cable as standard I/O. The CPU supports fail-safe programming in LAD and FBD (each including failsafe libraries), meeting SIL 3 requirements without a separate safety bus. The process image accommodates 32 kbyte each for inputs and outputs, which means all I/O points can be accessed in one bus cycle without additional backplane access optimizations. This is critical for high-speed applications like packaging or machine tools. The hardware clock type ensures time-stamped diagnostics across the network.
