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 space-saving control cabinet integration, the Beckhoff C6515-0050 delivers industrial-grade processing power with a completely fanless passive cooling design. By utilizing an external heat sink structure that projects through the wall of a control cabinet or control housing, this built-in Industrial PC isolates internal electronic components from ambient environmental factors while ensuring efficient thermal dissipation. The unit features an Intel Celeron 2000E dual-core processor, a highly expandable motherboard design, dual-slot CFast media slots, and high IP-rated sealing, making it ideal for heavy-duty automation and control architectures.
| Parameter | Value |
|---|---|
| Manufacturer | Beckhoff |
| Model/Article Number | C6515-0050 |
| Processor | Intel Celeron 2000E (2.2 GHz, 2 Cores) |
| TwinCAT 3 Performance Class | TC3: 50 (Mid-range) |
| Motherboard | 3.5-inch motherboard (4th Generation Intel Core platform) |
| System Memory | 2 GB DDR3L RAM (expandable to 16 GB) |
| Storage Interface | 2x CFast slots (4 GB CFast card included) |
| Ethernet Controller | On-board dual Gigabit Ethernet (2x 100/1000BASE-T) |
| Power Supply Input | 24 V DC |
| Sealing Protection | IP65 (outside/heat sink), IP20 (inside/cabinet) |
| Operating Temperature Range | Outside: 0 to 45 degC, Inside: 0 to 55 degC |
| Physical Dimensions (W x H x D) | 240 x 230 x 81 mm (9.5 x 9.1 x 3.2 inches) |
| Weight (Basic Configuration) | 3.0 kg (6.61 lbs) |
| Shipping Weight (Calculated) | 4.0 kg (8.82 lbs) |
| Port / Interface Type | Description / Terminal Function |
|---|---|
| LAN1 / LAN2 | RJ45 ports for dual independent Gigabit Ethernet connections |
| DVI Connection | 1x DVI-D display interface for direct connection to control panel |
| USB Ports | 2x USB 3.0 ports, 2x USB 2.0 ports |
| Serial Port | 1x RS232 standard serial COM interface |
| Power Input | 3-pin 24 V DC power supply connection terminal block |
The C6515-0050 features a 4th Gen Intel Celeron CPU which maps to TwinCAT 3 performance class TC3: 50. If you are replacing an older C6515-0010 or C6515-0020, verify your TwinCAT licensing; upgrades from performance class 30 or 40 runtime systems may require core license migration. Always back up the existing TwinCAT system files and the local NOVRAM storage image prior to replacement.
Because this is a completely fanless unit relying on convection cooling via its external heat sink, proper cabinet mounting is critical. Inadequate thermal dissipation on the heat sink side will lead to thermal throttling under high CPU utilization. Ensure that the external enclosure provides sufficient heat dissipation surface or ventilation to keep the heat sink environment below 45 degC.
Do not hot-swap CFast cards while the industrial PC is energized, as this can corrupt the file allocation tables or cause an unexpected OS blue screen. For optimal noise rejection in environments with heavy electromagnetic interference (such as those containing variable frequency drives), the functional earth (FE) wire must be terminated securely to the chassis ground screw using a low-impedance copper strap.
