6ES7964-2AA01-0AB0 SIEMENS

A Siemens processor module functions as the brain of a Programmable Logic Controller (PLC) system. It continuously executes the control logic stored in its memory by scanning inputs, running program blocks, and updating outputs. Equipped with specialized microprocessors, real-time operating systems, and integrated communication ports, it ensures fast execution times, high precision, and reliable real-time control. Advanced variants include integrated safety features for fault-tolerant applications and built-in web servers for remote diagnostics.

Product Parameters
