Beckhoff CP-Link System Description
Example: CP-Link "Double" Connection
One Control Panel with Touchscreen and one Control Panel with
Touchpad
If we assume that the Control Panel with touchpad is connected to CP-Link
1 and that the Control Panel with touchscreen is connected to CP-Link 2,
then the signals from the one Control Panel for the touchpad (RS232) from
CP-Link 1 are passed to COM2, and the signals from the touchscreen
(RS232) of the other Control Panel are passed to COM 1. The keyboard
cable to the motherboard must be plugged into the card on the outside (CP-
Link 2). Further, a 1:1 connection from ST305 (CP-Link 1) to ST304 (CP-
Link 2) is required in order to pass the keyboard signals arising from CP-
Link 1 on to CP-Link 2.
The drivers must be installed in accordance with the assignments of the
touchpad and touchscreen.
The BNC cables are connected to the "CP-Link A" and "CP-Link B"
connectors on the CP-Link card. Orientation is aided by a red mark on the
card. The cable types and the corresponding lengths are described below.
