Yaskawa CP-317/218IF High-Speed System Controller

Yaskawa CP-317/218IF High-Speed System Controller

The Yaskawa CP-317/218IF is a high-performance integrated controller part of the Control Pack (CP) and CP-9200SH series. 

It is designed for large-scale industrial systems requiring rapid sequence control and sophisticated motion synchronization.

The model name refers to the combination of the CP-317 CPU module and the 218IF communication interface, which provides Ethernet connectivity.

 This allows the controller to act as a master station for complex manufacturing plants, coordinating between multiple sub-controllers, HMIs, and engineering workstations.

Technical Parameter Table

Product Advantages and Features

High-Speed Execution: Designed for complex arithmetic and high-speed motion synchronization, making it ideal for high-throughput production lines.

Open Networking: The 218IF module provides robust Ethernet communication, supporting standard protocols like MEMOBUS/TCP and Modbus/TCP for seamless integration with third-party software (SCADA/HMI).

Fault Tolerance: Features ECC memory to automatically correct single-bit errors and detect multi-bit errors, ensuring system stability in environments with high electrical noise.

Backward Compatibility: Fully compatible with earlier CP-series hardware and software, allowing for easy upgrades of legacy systems without rewiring.

Multi-Level Programming: Supports hierarchical drawing (DWG) structures, enabling engineers to separate high-speed control tasks from background monitoring tasks.

Application Cases

The CP-317/218IF is commonly found in "heavy" automation sectors:

Steel and Metallurgy: Controlling rolling mills and blast furnace charging systems where reliability and speed are paramount.

Water & Sewage Treatment: Serving as the master controller for wide-area distributed I/O systems in municipal infrastructure.

Automobile Assembly: Coordinating large robotic welding lines and synchronized conveyor systems.

Papermaking & Printing: Managing complex tension control and high-speed synchronization between multiple rollers.
