6ES7515-2RM00-0AB0 SIEMENS SIMATIC S7-1500R Redundant CPU High Availability Controller
The SIEMENS 6ES7515-2RM00-0AB0 is a high-availability redundant programmable logic controller (PLC) from the SIMATIC S7-1500R/H automation family. Officially named the CPU 1515R-2 PN, this advanced controller is engineered for mission-critical applications where maximum system uptime, fault tolerance, and seamless failover are essential—such as in water/wastewater treatment, power distribution, oil & gas, railway systems, and continuous process industries.
Unlike standard PLCs, the 6ES7515-2RM00-0AB0 operates in a synchronized redundant pair: two identical CPUs run in parallel, sharing program execution, I/O data, and communication status in real time via a high-speed Redundant Sync Module (RS) connection. If one CPU fails, the standby unit takes over within milliseconds—without interrupting control or communication.
