Designed for the Simatic S5 platform, Siemens 6ES5946-3UR21 is a Processor Module.
Within the process-control arrangement, controller hardware forms a central decision-making element in the system, processing configured logic and exchanging information with I/O, operator, and communication components as supported by the installed platform. Application should remain aligned with the documented system design.
SIMATIC S5 is a modular PLC platform used in established machine and process-control installations. This product supports the PLC modules function assigned within the compatible S5 hardware configuration. Installation should follow the control node's approved hardware records.
For maintenance or replacement work, the exact module designation should be checked against the installed hardware, wiring records, and control-system documentation before the component is placed into service. The documented module assignment should remain the basis for selection.
