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.
To integrate standard legacy fieldbus communication into modern control networks, the Beckhoff EL6731-0010 acts as a dedicated PROFIBUS DP slave terminal within the modular EtherCAT Terminal system. This compact terminal enables direct communication between an EtherCAT network master and any upstream PROFIBUS DP master controller. Incorporating an optimized, non-volatile memory structure, the device offers highly flexible cyclic data exchange capacities, accommodating process images up to 1.4 kbytes of input and 1.4 kbytes of output data. By mapping PROFIBUS diagnostics, configuration parameters, and alarm states directly to the EtherCAT process image, it ensures high diagnostic transparency and seamless cross-platform control synchronization.
| Specification | Value |

| Data Transfer Rates | 9.6 kbaud to 12 Mbaud |
| Interface Type | 1 x D-sub socket, 9-pin, galvanically decoupled |
| Process Image Memory | Max. 1.4 kbyte input / 1.4 kbyte output data |
| E-bus Current Consumption | Typical 350 mA |

| Storage Temperature | -40 to +85 degC |
| Dimensions (W x H x D) | 24 mm x 100 mm x 52 mm |
| Housing Material | Polycarbonate (compact terminal housing) |
| Protection Class | IP20 |
| Environmental Standards | Conforms to EN 60068-2-6 (Vibration) and EN 60068-2-27 (Shock) |
| Approvals & Markings | CE, UL, ATEX (II 3 G Ex nA IIC T4 Gc) |
| Net Weight | 70 g |
| Shipping Weight (Calculated) | 0.25 kg |
| D-Sub 9-Pin Connector | Signal Assignment | Description |
|---|---|---|
| Pin 3 | RxD/TxD-P | Receive/Transmit Data - Positive (B-Line, Red) |
| Pin 5 | DGND | Data Ground (Reference potential for VP) |
| Pin 6 | VP | Supply Voltage Plus (+5V for terminating resistors) |
| Pin 8 | RxD/TxD-N | Receive/Transmit Data - Negative (A-Line, Green) |
| Metal Frame | Shield | Functional Earth Shielding Connection |
Do not confuse the EL6731-0010 (Slave module) with the standard EL6731 (Master/Scanner module). While both share the same physical 24 mm housing, their firmware profiles are entirely different. The EL6731-0010 is addressed in TwinCAT exclusively as an EtherCAT-to-PROFIBUS slave box, requiring a GSD file for configuration on the upstream master controller.
Since this terminal lacks physical rotary switches for manual PROFIBUS slave address setting, the node address must be assigned programmatically through the TwinCAT System Manager via the EtherCAT CoE (CoE index 0xF800:01) or standard GSD assignment. If using multiple high-draw communication cards on a single E-bus rail segment, carefully track your cumulative E-bus current. The EL6731-0010 draws a substantial 350 mA, meaning you may need an EL9410 power supply booster terminal on the right-hand side of the segment to avoid voltage drops.
To prevent high-frequency reflections and transmission errors, ensure that standard active RS485 termination is enabled at the end of the physical PROFIBUS line. The internal DB9 port of the EL6731-0010 provides +5V (Pin 6) and DGND (Pin 5) to supply a standard active termination connector. Always ground the DIN rail reliably to allow the terminal's rear grounding contact spring to discharge electrical noise efficiently.
