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.
Engineered for high-performance multi-axis synchronization, the Mitsubishi Electric Q173CPUN serves as a dedicated motion CPU within the MELSEC Q Series platform. This controller seamlessly integrates on the same base unit alongside standard Q Series PLC CPUs, distributing processing loads to achieve precise synchronization of complex machinery. It supports advanced motion control tasks such as virtual axis configuration, electronic camming, and synchronized gear operations while relying on highly immune fiber-optic communication interfaces to interface with external servo amplifiers.
| Manufacturer | Mitsubishi Electric |
| Model | Q173CPUN |
| Series | MELSEC Q Series |
| Module Type | Motion Controller CPU Module |
| Number of Control Axes | Up to 32 axes |
| I/O Points | 8192 points |
| Program Capacity | 14k steps |
| Motion Network | SSCNET III (Fiber-Optic) |
| Operating Temperature | 0 to 55 degC |
| Storage Temperature | -25 to 75 degC |
| Shipping Weight (Calculated) | 3.0 kg |
| Package Dimensions (Calculated) | 150 mm x 120 mm x 100 mm |
| Interface Type | Physical Description & Function |
|---|---|
| SSCNET III Ports | Optical fiber connector sockets for high-speed synchronization communication to MR-J3/MR-J4 series servo amplifiers. |
| Multi-CPU Interface | High-speed backplane connector matching the MELSEC Q Series main base unit slot allocation. |
| USB Connection | Peripheral communication port for commissioning, configuration downloading, and real-time trace diagnostics. |
When migrating from older non-N models like the Q173CPU, verify the physical network layout. The standard Q173CPU uses copper-based SSCNET, while the Q173CPUN utilizes fiber-optic SSCNET III. This shift requires changing the communication cables to optical fiber and ensures the corresponding servo drives support SSCNET III protocols.
Backplane power calculation is critical. Because a motion controller CPU draws higher current from the backplane 5V supply than standard digital I/O modules, you must sum the current consumption of the PLC CPU, the Q173CPUN, and all host modules to prevent overload on the system power supply (e.g., Q61P vs Q63P).
Handle the SSCNET III optical fiber cables with extreme care during panel wiring. Maintaining a minimum bend radius of 25 mm is critical; exceeding this limit can lead to optical signal attenuation, causing mysterious communications failures or sporadic axis fault trips (such as code 32 or 10) during high-speed operation cycles.
