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.
Delivering rapid processing capabilities for high-performance automation, the Omron NX701-1620 provides execution of complex motion and database logging algorithms directly within the controller core. This heavy-duty system controller acts as the central command unit for large-scale production facilities, synchronizing high-speed sequence programs and multi-axis trajectory profiles. By integrating native direct SQL database connectivity and an embedded OPC-UA server, it bridges the gap between the plant floor and IT-level enterprise systems without requiring gateway PCs or specialized middleware.
| Parameter | Specification |
|---|---|
| Manufacturer | Omron |
| Model Number | NX701-1620 |
| Controller Series | Sysmac NX7 |
| Task Cycle Time | 0.125 ms |
| Program Memory | 80 MB |
| Variables Memory | 260 MB |
| Max. Controlled Axes | 128 Synchronous Axes |
| Communication Ports | EtherCAT (Master), EtherNet/IP (2 Ports), Ethernet TCP/IP |
| Local I/O Bus | NX I/O Bus System |
| Net Weight | 0.88 kg |
| Shipping Weight | 3.00 kg |
| Interface Port | Functional Protocol Assignment |
|---|---|
| Port 1 (EtherNet/IP) | Host communications, HMI interface, Tag Data Link networking, Sysmac Studio tool interface. |
| Port 2 (EtherNet/IP) | Secondary industrial network ring, direct SQL client execution, or OPC-UA server communications. |
| Port 3 (EtherCAT) | Deterministic servo drive control, distributed I/O couplers, high-speed remote nodes. |
| SD Card Slot | Logging spools, memory card storage, OS firmware updates, and system recovery. |
The NX701-1620 is configured within the Sysmac Studio platform. It replaces smaller controllers like the NX701-1600 (which is limited to 64 axes) in scenarios where mechanical expansions demand increased servo synchronization. Ensure that all program files are recompiled in Sysmac Studio version 1.10 or higher when converting code from older NX-series platforms.
When utilizing the direct SQL connection feature, ensure your database spooling configuration is active. If the destination database server goes offline, the controller utilizes internal memory blocks as a buffer. If the outage exceeds the buffer capacity, data overwrite warnings occur. Always set up appropriate diagnostic alarms to monitor SQL transaction queues.
High-density multi-axis EtherCAT loops require high-quality STP Cat5e (or better) industrial Ethernet cables. Poorly shielded or loose cabling will introduce microsecond jitter, resulting in intermittent packet loss and subsequent controller axis synchronization faults. Route network communication wires away from high-power servo motor cables.
