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 industrial environments requiring high hygiene standards and reliable operator feedback, the Beckhoff CP3918-1414-0010 functions as a robust human-machine interface featuring an integrated 18.5-inch widescreen display. Encased in a premium 1.4301 stainless steel housing with a flush-laminated glass front, this control panel provides multi-finger touch operation and splinter protection for safety-critical applications. Built-in physical control elements, including illuminated short-stroke keys and an integrated emergency stop button, ensure direct manual operation is always accessible. With its advanced CP-Link 4 technology, the device transmits video signals, USB 2.0 data, and power over a single Cat.6A cable up to 100 meters, eliminating complex localized wiring topologies.
| Parameter | Specification Value |
|---|---|
| Manufacturer | Beckhoff Automation |
| Model Number | CP3918-1414-0010 |
| Display Size | 18.5-inch (widescreen) |
| Resolution | 1366 x 768 pixels |
| Touch Interface | Multi-finger touch, flush-laminated, splinter protected |
| Housing Material | 1.4301 stainless steel with continuous glass surface |
| Push Button Array | 3 x 19 mm round short-stroke keys with RGBW LED rings (USB connected); 2 pre-labeled "I" / "0" |
| Emergency Stop | RAFI RAFIX 22FS+ with 2 normally closed (NC) contacts |
| Connection Standard | CP-Link 4 (Single Cable Technology / One Cable Technology) |
| Maximum Cable Distance | 100 meters via Cat.6A cable |
| Communication Rates | USB 2.0 at 100 Mbit/s, digital video signals |
| External USB Interfaces | 1 x USB Type A socket with IP65 screw-on cap |
| Ingress Protection Rating | IP65 (all-around protection) |
| Operating Temperature | 0 to 45 degC |
| Mounting Pattern | 6 x M5 threaded holes for mounting arm adapter |
| Country of Origin | Germany |
| Shipping Weight | 12.00 kg |
| Connector / Interface Type | Terminal Assignment & Function |
|---|---|
| M12 Round Connector (CP-Link 4) | Transmits high-speed DVI and USB 2.0 signals; handles primary connection to PCIe transmitter cards. |
| M12 Round Connector (Optional 24V Power) | Dedicated external 24 V DC power supply input (used in dual-cable configuration). |
| 4-Pin Round Connector | Wired directly to the two normally-closed (NC) emergency stop contacts on the RAFI RAFIX 22FS+ switch. |
| USB Type A Socket | Front-accessible port with an IP65 screw cap for system configuration and maintenance. |
The CP3918-1414-0010 belongs to the premium stainless steel hygienic range. It acts as a direct upgrade to legacy CP3918-series models lacking the integrated mechanical push-button options. When configuring this unit, ensure your PCIe transmitter module (such as the Beckhoff CU8802 for single-cable connection or CU8803 for dual-cable setups) is fully compatible with the specified CP-Link 4 standard. If replacing a standard anodized aluminum control panel, the 1.4301 stainless steel housing's chemical resistance profile must be considered for compatibility with CIP (Clean-in-Place) chemicals used on site.
Because this control panel utilizes a fully sealed IP65 stainless steel housing without active internal cooling fans, heat dissipation relies solely on natural convection through the metallic rear chassis. Do not mount the rear surface flush against insulating walls or near radiating heat sources. Maintain a minimum ambient clearance of 100 mm around the back enclosure to ensure the operational temperature does not exceed 45 degC. Additionally, when using Cat.6A cables for the 100-meter CP-Link 4 run, routing alongside high-frequency power lines or variable frequency drive (VFD) outputs can cause signal dropouts; always use double-shielded STP cables grounded at both ends.
When wiring the RAFI emergency stop circuit, always use dual-channel routing back to your safety relay or safety PLC (e.g., Beckhoff EL2904) utilizing both NC contacts mapped to the 4-pin round connector. For the illuminated push buttons, ensure the USB driver interface is properly enumerated in your TwinCAT 3 environment. The custom RGBW LED rings can be addressed programmatically via internal software function blocks to reflect plant statuses such as 'running', 'fault', or 'idle'.
