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 optimize visualization on the plant floor, the Mitsubishi Electric GT1572-VNBA acts as a robust human-machine interface within the high-performance GOT1000 Series. Engineered for demanding industrial control environments, this 10.4-inch graphic operation terminal features a high-durability TFT color liquid crystal display designed to stream precise machine metrics and operational data to automation technicians. Operating on a wide-range AC power source, the module integrates easily with MELSEC series PLCs and multi-vendor field equipment.
| Manufacturer | Mitsubishi Electric |
| Model Number | GT1572-VNBA |
| Product Series | GOT1000 Series (GT15) |
| Display Type | TFT Color Liquid Crystal |
| Screen Size | 10.4 inches |
| Resolution | 640 x 480 dots |
| Display Dimensions | 211(W) x 158(H) mm |
| Display Color | 16 colors |
| Input Supply Voltage | 100 to 240 V AC (+10%, -15%) |
| Input Frequency | 50/60 Hz (+/- 5%) |
| Power Consumption | 28 W or less |
| Max Apparent Power | 110 VA (at maximum load) |
| Inrush Current | 40 A or less (duration 4 ms at maximum load) |
| Shipping Weight | 4.0 kg |
| Port Type | Interface & usage Details |
|---|---|
| Serial Comm Port 1 | Built-in RS-232 interface for PC or PLC communications |
| Serial Comm Port 2 | Built-in RS-422/485 multi-drop communication channel |
| USB Ports | Built-in USB Type A and Mini-B for configuration transfer or storage |
| Memory Slot | CF card slot for data logging, backup, and OS deployment |
The GT1572-VNBA functions as a drop-in replacement within the GT15 family of the GOT1000 Series. When replacing older systems or upgrading from older GT11/GT15 units, confirm the communication modules installed on the rear expansion slots (e.g., CC-Link, Ethernet, or Bus connections) as these option boards must be moved over to the new HMI unit to preserve network mapping. Use GT Designer3 software to convert older project files (.g2 or .g1 files) to current workspace files.
The CCFL backlight tube utilized in this specific unit has a finite operating life. In high-temperature electrical panels, ensure there is a vertical clearance of at least 100mm from nearby heat-producing elements (such as variable frequency drives or power supplies) to avoid premature display dimming or color degradation. Maintain proper cabinet ventilation to ensure internal HMI temperature remains within nominal ranges.
When wiring serial interfaces to MELSEC series PLCs over RS-422/485 networks, always use double-shielded twisted pair cables. It is critical to land the frame ground (FG) terminal of the GT1572-VNBA directly to a low-impedance earth ground to suppress EMI noise. Do not share this ground with heavy-current drive machinery.
Isolate and lock out all external power sources before executing mechanical cutouts or wiring connections on this graphic terminal. Operating the unit while energized can lead to hardware failure, electrical shock, or personal injury.
Ensure the mounting panel has a thickness between 2.0 mm and 10.0 mm to achieve proper compression of the environmental sealing gasket.
Insert the terminal into the panel cutout and secure it from the rear using the provided mounting fixtures. Tighten screws evenly to the specified torque rating (0.36 to 0.48 N-m) to prevent housing distortion.
Connect the external AC power source (100 to 240 V AC) using wires with a cross-section of at least 2.0 mm2. Tighten terminal block screws securely to prevent loose connections.
Verify correct ground path routing, re-energize the supply circuit, and upload the target visual configuration project via GT Designer3.
