Product Description

Detailed Description:

  • Exceptional Performance: This CPU integrates 1 MB of work memory and executes a binary instruction in just 0.05 µs. It supports a large number of program and data blocks, enabling efficient handling of complex control algorithms, data management, and technological functions.

  • Dual Integrated Industrial Networks: The module integrates two key communication interfaces. The first is an MPI/PROFIBUS DP combo interface, which can function as a DP master to connect traditional distributed I/O. The second is a PROFINET IO interface (dual-port, with switch functionality), supporting Real-Time (RT) and Isochronous Real-Time (IRT) communication, suitable for high-speed, precise distributed I/O control.

  • Powerful Expandability: The CPU 317-2 PN/DP allows for large-scale expansion of the S7-300 system with up to 32 modules and can connect to up to 128 IO devices via PROFINET IO.

  • Integrated Technological Functions: Supports integrated motion control for multiple axes, as well as advanced closed-loop control tasks like PID control.

  • Reliable Storage: The user program and data are stored on a Micro Memory Card (MMC), enabling maintenance-free, battery-less operation. The MMC card provides up to 8 MB of load memory.

  • Application Areas: Widely used in high-performance automation systems in industries such as automotive manufacturing, food & beverage, packaging, and material handling, where stringent requirements for processing speed and network communication exist.
