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.
Optimized for space-conscious machine-level monitoring, the Mitsubishi Electric GT1150-QBBD-C is a high-performance operator terminal belonging to the specialized GT11 sub-series of the GOT1000 platform. This hardware features a 5.7-inch STN blue-mode monochrome graphical display, engineered to deliver legible diagnostic feedback and interface layouts in challenging industrial environments. Equipped with an onboard 3 MB flash memory system, the unit handles complex screen layouts, alarm histories, and multi-language character sets. Physical communication interfaces include high-speed RS-232, RS-422/485 serial ports, and a dedicated USB connection, enabling robust connectivity directly to MELSEC series controllers or modern manufacturing networks.
| Parameter | Specification |
|---|---|
| Manufacturer | Mitsubishi Electric |
| Model Reference | GT1150-QBBD-C |
| Series Name | GOT1000 (GT11 Platform) |
| Display Unit | STN Monochrome (Blue/White) LCD |
| Screen Size | 5.7 Inches |
| Display Resolution | 320 x 240 Pixels |
| Supply Voltage | 24 V DC (+10%, -15%) |
| User Memory Capacity | 3 MB Built-in Flash |
| Backlight Type | Cold cathode fluorescent tube (Replaceable) |
| External Interfaces | RS-232, RS-422/485, USB (Mini-B) |
| Memory Extension Slot | CompactFlash (CF) Card Slot (Max 2 GB) |
| Protection Rating | IP67f (Front section when panel mounted correctly) |
| Operating Temperature | 0 to 50 degC |
| Shipping Weight (Calculated) | 1.45 kg |
| Package Dimensions (Calculated) | 230 mm x 195 mm x 95 mm |
| Connector / Port | Interface Specification | Functional Use |
|---|---|---|
| RS-422/485 | D-Sub 9-pin Female | Primary PLC connection channel (MELSEC or major third-party protocols) |
| RS-232 | D-Sub 9-pin Male | Peripheral devices (scanners, printers) or serial PC upload/download |
| USB Device | Mini-B Port | High-speed screen design transfer, software communication, and OS updates |
| Power Terminal | Screw Terminal Block | 24 V DC power supply input with physical protective ground point |
The GT1150-QBBD-C variant features a conformal protective coating designed for harsh operating environments, distinguishing it from standard, non-coated GT1150-QBBD baseline models. When upgrading to this unit from legacy GOT900 series terminals (such as the F940GOT or GT10 series), screen databases can be seamlessly converted utilizing the migration wizard within GT Designer3. Ensure all communications drivers are updated to support the GT11 system architecture during project migration.
As an STN monochrome blue LCD, the screen contrast of this unit is inherently susceptible to temperature shifts. In high-temperature electrical panels, the screen's baseline contrast may drop, leading to ghosting or low visibility. Users should utilize the built-in system utility screen to modify contrast registers or set up automatic contrast adjustments based on temperature. Ensure the surrounding panel cabinet retains a positive air draft if continuous exposure to temperatures close to 50 degC is expected.
To avoid communications dropouts or damage to the transceiver components, never route the RS-422/485 serial communication cables adjacent to 480 V high-current motor cables or variable frequency drive (VFD) output wires. Always attach a physical grounding strap to the grounding terminal of the terminal block to divert electromagnetic interference. When accessing the CF card slot, ensure the interface is unmounted or the device is powered off before ejecting the media card to avoid project data corruption.
CRITICAL WARNING: RISK OF ELECTROCUTION AND EQUIPMENT CRASH
Ensure all primary AC and subsidiary DC power sources feeding the target enclosure are fully locked out and tagged out prior to making physical cuts or performing wiring on the GT1150-QBBD-C. Use a calibrated multimeter to verify that the power lines are completely dead and that there are no residual energy pathways.
Verify the panel cutout meets the mandatory physical mounting dimensions for standard 5.7-inch GOT1000 panels.
Ensure the high-performance waterproof packing gasket is positioned flat, secure, and clear of debris inside the front bezel track of the device.
Insert the terminal into the panel cutout and tighten the four mounting screws systematically to the OEM-specified torque to avoid cracking the case.
Attach the dedicated 24 V DC supply leads to the screw terminals. Turn on power, enter the terminal configuration menu, and verify the physical system connection parameters match your controller.
