The SIMATIC CP 5611 is a communication processor from Siemens, specifically designed for use in industrial automation and control systems. It is part of the SIMATIC series of products, which are used to connect a PC to an S7 PLC (Programmable Logic Controller) or other industrial networks. The CP 5611 typically acts as an interface for communication between a computer (running Windows) and a Siemens PLC system over MPI (Multi-Point Interface) or Profibus networks.

The SIMATIC CP 5611 Windows driver is the software that allows your computer to interface correctly with the CP 5611 hardware. The driver facilitates communication between the PC and the Siemens automation hardware, ensuring data can be exchanged between the computer and the PLC.
