By facilitating remote I\/O processing directly at the machine level, this module eliminates the need for protective control cabinets and extensive parallel wiring. It dynamically handles both digital and analog peripheral signals, automatically matching the requirements of connected extension interfaces. Network configuration is easily managed using the KS2000 software tool or via explicit messaging through the host controller.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;
