Product features

Mitsubishi R04ENCPU is a standard CPU module from Mitsubishi Electric's MELSEC iQ-R series that is optimized for small and medium-sized industrial automation control systems. The LD instruction is processed in 0.98 ns, whereas the MOV and ST instructions (containing IF, CASE, and FOR) take 1.96 ns. Mitsubishi R04ENCPU's PC MIX value of 419 instructions per microsecond allows it to respond swiftly to diverse control commands and accomplish complex logic operations without delay. Mitsubishi R04ENCPU stands out from similar products because to its high-speed performance, making it ideal for scenarios requiring real-time response, such as manufacturing line control and packaging machines operation.

The Mitsubishi R04ENCPU also has ample memory capacity to run numerous programs and save data. It has a program capacity of 40K steps (160K bytes) and 400K bytes of device/label memory, allowing for the storage of a large number of control programs, process parameters, and operational data. The data memory is 1072K bytes (536K words), with 24K words of fixed scan communication space to fulfill the data exchange needs of various devices. Furthermore, the Mitsubishi R04ENCPU supports SD/SDHC card expansion with a maximum capacity of 32GB, allowing users to effortlessly back up and store programs and data, greatly simplifying daily maintenance and software upgrades.

In terms of I/O capacity, the Mitsubishi R04ENCPU can accommodate the majority of small and medium-sized automation systems. It can accommodate up to 4096 I/O points (local and remote), with the network taking up 32 intelligent I/O points. It contains 12,288 fixed input (X)/output (Y) points, 12,288 internal relays (M), and 18,432 user-modifiable data registers (D), as well as a maximum of 160K file registers. Mitsubishi R04ENCPU's flexible I/O design allows it to be compatible with a wide range of I/O modules and intelligent devices, making it extremely adaptable to a variety of control scenarios.

Precautions

First and foremost, pay attention to the Mitsubishi R04ENCPU's power supply needs. The Mitsubishi R04ENCPU must be powered by a 5V DC dedicated power module from the MELSEC iQ-R family; do not use an unqualified or mismatched power source. Before turning on the power, ensure that the power voltage is stable and that the power connection is tight to prevent harm to the Mitsubishi R04ENCPU caused by voltage fluctuations or bad contact. Furthermore, do not plug or remove the power cord while the Mitsubishi R04ENCPU is operating, as this may result in data loss or module failure.

Second, the installation of the Mitsubishi R04ENCPU must adhere to applicable rules. Install the Mitsubishi R04ENCPU inside a control panel to prevent direct exposure to sunlight, rain, dust, or corrosive gases. The installation position should be stable and free of vibration or impact during operation, since the Mitsubishi R04ENCPU has rigorous shock and vibration resistance requirements, and excessive vibration may compromise its internal components and processing performance. When installing, keep a safe distance from other heating equipment to avoid overheating, as the Mitsubishi R04ENCPU's standard working temperature is 0-55°C.

FAQ

Q: What is the Mitsubishi R04ENCPU?

A: The Mitsubishi R04ENCPU is a programmable controller CPU module from the MELSEC iQ-R series. It is classified as a conventional CPU with a built-in CC-Link IE controller network, intended for mid-scale automation systems requiring integrated, high-speed networking.

Q: What is the main difference between the R04ENCPU and a standard R04CPU?

A: The key differentiator is the integrated network. The "EN" in R04ENCPU indicates that it includes a built-in CC-Link IE network interface. This module has two Ethernet ports on the network side that can serve as gateways, while the CPU-side Ethernet port is utilized for conventional Ethernet communications. In comparison, the basic R04CPU lacks this built-in industrial networking capabilities.

Q: What are the high-speed signal processing capabilities of the R04ENCPU?

A: The Mitsubishi R04ENCPU excels in executing constant cycle interrupt programs with a minimum interval of 50 microseconds (µs). This enables the PLC to properly read very high-speed signals regardless of the primary scan time, which is perfect for production lines with fast-moving products.
