When data changes are requested, the controller responds and executes the changes quickly and efficiently. The high-speed interaction between operator, network and controller is due to several factors including well written firmware, parallel processing sub networks, high scan rates and "modular" object oriented programming. The result delivers outstanding operator to network performance and exceptional value.
