NZ2MC-1MBS bộ nhớ mở rộng SRAM MELSEC iQ-R Series CPU

Programmable Controller CPU Modules

At the core of the MELSEC iQ-R Series is a programmable controller CPU. This CPU is the heart of the control system and includes various features for different applications. The most common CPU is the programmable controller CPU, into which various features are embedded, enabling it to perform a wide range of control tasks. The different CPUs are highly scalable with five types available, based on program capacity needs (10K to 1200K steps). In addition, a CC-Link IE embedded CPU is available, further reducing hardware costs as a separate network module is not required.

*6: Extended SRAM cassette expands the device/label memory area.
*7: The IF or FOR sentence of the structured text consists of several instructions, which may increase the processing time period.
*8: Average number of instructions such as for basic instructions and data processing executed in 1 µs. The larger the value, the faster the processing speed.
*9: Available with R□ENCPU. For details about network specifications, refer to the RJ71EN71 performance specifications.
*10: The following networks are supported, Ethernet, CC-Link IE Control (twisted pair cable), and CC-Link IE Field (two simultaneous Ethernet networks and combined CC-Link IE Field and CC-Link IE Control networks are not supported).
*11: Logging data can be saved in the SD memory card only.
*12: Depends on supported CPU firmware version, for more information please refer to the related product manual.
