BECKHOFF CP9035

The connection from the Control Panel to the PC itself is made via CP Link, a transmission technology having a data rate in the gigabit range. CP Link implements transmission segments up to 100 m on a twin-core coaxial cable. No additional power supply is needed. The CP-Link Interface is implemented as an ISA and PCI bus plug-in card and is thus usable in any PC. The PC is also equipped with a graphics card providing an LCD interface. The PC ports for LC display, keyboard, COM ports, PS/2 mouse and floppy drive are converted by the CP-Link plug-in card into a highfrequency serial signal and transmitted via coaxial cable to the Control Panel. The CP-Link Interface in the Control Panel re-converts the serial signal for the original PC ports, to which the components of the Control Panel, such as keyboard, LC display, touch screen, touch pad, PS/2 mouse and floppy drive are connected, but at a 100 meters longer distance than would ordinarily be possible. There is a CP-Link channel for each direction of the communication between the Control Panel and the PC. Two coaxial cables are laid for this reason.
