Key issues
What are the advantages of GILOGIK II’s GDnet network compared to regular Ethernet, and how many nodes can it support up to?
Answer: GDnet is a GEFRAN dedicated real-time Ethernet that achieves 100 μ s I/O refresh, zero jitter synchronization, and much higher certainty than regular Ethernet; The system supports up to 16 nodes, with a maximum of 256 I/O points per node, meeting the requirements of high-speed distributed control.
What are the positioning differences between GT-C, GT-O, and GF-BOX, and in what scenarios are they used?
Answer: GT-C is a panel integrated controller with a screen and buttons, used for device main control operations; GT-O is a pure remote control screen with no computing power, and can be connected to GF-BOX up to 25m away; GF-BOX is a cabinet mounted industrial control computer responsible for computation, and is paired with GT-O to achieve separation of main control and operation.
What are the key designs for wiring and installation of GILOGIK II modules, and what benefits can they bring?
Answer: Adopting a spring type screw free connector, the wiring does not require tools and is fast and reliable; Module buckle installation, no need for screw insertion and removal; Base plate geographic addressing, can be plugged into any slot; The overall design significantly reduces installation and maintenance time, and improves system reliability and vibration resistance.
