Implementing 3-Switch XOR Ladder Logic with Internal Bit
Implement a 3-SPST switch XOR light circuit in LogixPro or RSLogix 500 using an internal relay bit. Includes truth tables, boolean equations, and verified.
Designed for high-performance visualization directly at the machine level, the Beckhoff CP3918-0000 integrates a widescreen 18.5-inch display with robust multi-touch interface technologies. Operating as an industrial-grade display terminal, this unit utilizes DVI-E and USB-E 2.0 transmission standards, enabling reliable remote operation at distances up to 50 meters from the industrial PC (IPC). Wrapped in a high-protection all-round IP65 housing, this control panel withstands demanding physical environments while maintaining precise multi-finger capacitive input sensitivity.
| Specification Parameter | Technical Rating / Value |
|---|---|
| Manufacturer | Beckhoff Automation |
| Model Reference | CP3918-0000 |
| Display Size & Aspect Ratio | 18.5-inch (16:9 widescreen) |
| Resolution | 1366 x 768 pixels |
| Touch Technology | Projected Capacitive Touch (PCT) Multi-touch |
| Interface Standard | DVI-E and USB-E 2.0 |
| Maximum Cable Length | 50 meters |
| Operating Voltage | 24 V DC (minus 15 percent / plus 20 percent) |
| Protection Class | IP65 (all-round) |
| Operating Temperature | 0 to 55 Celsius |
| Housing Construction | Aluminum housing with laminated safety glass front panel |
| Mounting Connection | 4 x M6 threaded holes (100 x 100 mm pitch) / 48 mm tube adapter |
| Shipping Weight (Calculated) | 5.0 kg (11.0 lbs) |
| Port / Connection Terminal | Signal / Interface Description |
|---|---|
| 24 V DC Power Supply Input | 3-pin connection (+24 V, 0 V, Functional Earth) |
| DVI-E Connector | Industrial DVI-D input from PC transmitter over extended line |
| USB-E 2.0 Connector | Industrial USB-E 2.0 type B connector for touch and peripheral return |
| External USB Ports | IP65-rated USB ports for connecting external flash drives/peripherals |
The CP3918-0000 control panel operates strictly as a display and touch terminal without an integrated CPU or operating system. Host integration requires a specialized transmitter unit on the PC side, such as the CU8801 (USB-E-2.0 extender) or equivalent Beckhoff PCIe module cards. If your machine architecture features a localized computer, consider upgrading to the CP2918 series, which features built-in single-touch or multi-touch motherboard options.
When laying extended DVI-E and USB-E cables up to the 50-meter threshold, you must prevent tight bending loops inside the cable carrier tracks. Signal attenuation and jitter issues can disrupt the PCT touch tracking matrix if high-flex dynamic cables are used past their rated fatigue limit. Furthermore, avoid cascading external USB hubs at the display terminal end, as this may exceed USB timing margins over the extended 50-meter line.
To prevent "ghost touches" or erratic mouse behavior induced by variable speed drives (VSDs) and other high-frequency noise sources on the machine frame, ensure the mounting arm adapter has a direct, low-impedance copper ground connection to the main system ground. Use shielded, factory-terminated Beckhoff DVI-E/USB-E hybrid cables to maintain signal integrity.
