Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
Engineered for high-speed, multi-CPU automation architectures, the Mitsubishi Electric Q13UDEHCPU serves as a high-performance central processing unit within the MELSEC Q Series platform. This universal model features a dual-processor architecture that dramatically reduces program execution times, making it suitable for complex mathematical computations and high-density industrial applications. Boasting a built-in Ethernet port, the Q13UDEHCPU simplifies network integration, offering seamless peer-to-peer data exchange and direct PC-based monitoring without requiring additional communication modules.

The Q13UDEHCPU is a drop-in upgrade for older Q12HCPU and Q13HCPU models. However, because it belongs to the Universal QCPU generation, memory registration, file register structures, and programming software parameter sets differ. When converting programs in GX Works2/3, double-check your file register configurations (ZR vs R devices) as the Universal CPU manages standard RAM sectors differently than older High-Performance series.
When configuring a multi-CPU platform, calculate the total 5 VDC power consumption across the base unit. A combination of a Q13UDEHCPU (0.49 A), a motion CPU, and multiple Ethernet or fieldbus modules can easily exceed the power supply limits of standard power modules. Select a Q61P or Q62P power supply with ample overhead to prevent low-voltage system faults.
To prevent communication drops on the built-in Ethernet port under high electromagnetic interference (EMI), run STP (Shielded Twisted Pair) Category 5e or higher cabling. Ensure that the shield is grounded at the switch end. Avoid routing the Ethernet communication cable parallel to high-voltage AC motor lines or drive output cables in the wire ducting.
Disconnect all external power sources before installing, removing, or wiring any module on the MELSEC Q base unit. Failure to completely de-energize the rack can cause electrical shock, physical damage to the CPU processor pins, or erratic system operation.
Locate the CPU slot on the main base unit (typically the slot directly to the right of the power supply module, designated as CPU slot 0).
Hook the lower alignment tab of the CPU into the base unit's guide hole, ensuring the connector pins align perfectly.
Push the module firmly towards the base plate and secure it using the integrated lock screw at the top of the module to prevent dislodging due to vibration.
