Features^{Easy programming with flexible, large-capacity data storage}

• Max. 9882K words
• Easy programming
• Data utilization

• The MELSEC iQ-R Series programmable controller CPU module is designed to allow an extended SRAM cassette to be installed directly into the CPU module. This option makes it possible to increase internal device memory up to 9882K words, expanding device/label memory even further
• Management of programmable controller internal data is quite flexible, making programming even easier by allowing various data area allocations to be changed within the CPU memory and SRAM cassette
• Use of an SD memory card expands data logging memory, which allows data analysis by computer

Accurately detect high-speed signals

• Constant interrupt
• 50 µs of minimum interval time
• High-speed control

• Execute interrupt programs at a constant cycle (50 µs of minimum interval time) different from the scan time
• All signals are detected as input processing can be done faster than the scan time. This is ideal for a production line where products are traveling at high speed

Recorded event history can be checked when an error occurs

• Display in time-series
• Error cause identification
• Troubleshooting

• Operation and system historical events are automatically recorded in the programmable controller CPU module
• Actual changes to the program and system events with corresponding event codes can be displayed in sequence, allowing prompt error cause identification and troubleshooting

Easily collect manufacturing data

• Save in the internal memory
• Traceability
• Debug

• Utilizing the installed SD memory card, CPU internal memory or a direct live connection to the CPU module, logging data (device/label) can be easily collected just by simply registering the parameters. In addition, monitoring via USB or Ethernet in real-time is possible
• With the real-time monitor function of GX LogViewer, small changes in the target device can be easily identified, which is useful for factory traceability, equipment startup, and debugging in case of an error

Easy diagnostics/monitoring via a web browser

• CPU diagnostics
• Device block monitor
• Customized web page

• CPU diagnostics and device monitoring can be easily done via a web browser on a computer or tablet utilizing the CPU internal web server function
• Basic diagnostics are easily done without dedicated engineering software
• Customized “user web page” can be created and displayed in a layout according to applications^*2

Easy data coordination with third-party programmable controllers just by registering parameters

• Parameter registration only
• Coordination with third-party contollers
• Easy data collection

• The programmable controller CPU module allows device data exchange by parameter registration with Mitsubishi Electric programmable controllers and third-party programmable controllers (simple CPU communication function)^*3
• Data collection is easier without changing programs of the existing programmable controllers

• *4.Supported by the embedded Ethernet port only.

• *7.Supported version is “39” or later.
• *8.Supported version is “42” or later.

Serial connection

• *9.Supported version is “15” or later.

Easy data management utilizing internal database (DB)

• Internal DB
• Unicode®
• Multiple product variations

• Recipe data and production data, previously managed using a database server, can now be managed via the database in the programmable controller
• This feature allows a selection of database commands that can add/update/search/delete records to be utilized for simple recipe functions
• Accessing the CPU internal database data from a computer with Access® or Excel® is supported
• Utilized for changing recipe data and production management in the food and beverage industry where multiple product variations are produced using the same machine process

Battery-less module reduces maintenance cost

• The programmable controller CPU module for the medium-scale system (R00CPU/R01CPU/R02CPU) includes embedded non-volatile memory, thereby retaining latch data of device and label without requiring a backup battery when the power is off
• Other programmable controller CPU modules can also store latch data without a battery by installing a battery-less option cassette
• Periodical battery replacement is no longer required, reducing maintenance cost

Battery-less option cassette (NZ1BLC)-compatible module
