MELSEC iQ-R Series
Flexible, interchangeable system architecture
The MELSEC iQ-R Series is a modular control system equipped with various modules such as CPUs, power supply, digital I/O, analog I/O and base unit and intelligent function modules, each having its own responsibility in the system. The core of the system is a base unit that interconnects all of the modules together and enables high‑speed communications between each module. From small to large systems, scalability is simple. Up to seven extension bases can be connected and a maximum of 64 modules installed at any one time. An RQ extension base is also available, ensuring compatibility with existing MELSEC-Q Series modules.
Integrated safety control
The MELSEC iQ-R Series safety control system consists of a safety CPU that is compliant with international safety standards, ISO 13849-1 PL e and IEC 61508 SIL 3, and can execute both safety and general logic in the same CPU. The CPU module can be installed on a standard base unit and when paired with the safety function module enables control of safety I/O, realizing easy integration into an existing or new control system. Safety I/O such as an emergency stop switch or safety light curtain is controlled via CC-Link IE Field network, which is connected to the safety remote I/O module.
Highly scalable redundant control
The MELSEC iQ-R Series redundant control system is based on a dual-system architecture where all modules on a primary (control) system are duplicated onto a secondary (standby) system with a tracking cable connecting the systems together. Both systems are equipped with a process CPU module and redundant function module, with the former being able to execute standard logic and process control. This system supports local I/O configuration with a redundant extension base unit and remote I/O configuration with CC-Link IE Field Network, both can be configured with a dedicated base unit (standard/extended temperature) supporting redundant power supply modules.
Highly accurate synchronization
The MELSEC iQ-R Series system provides highly accurate synchronization between modules on the control system, which is realized through Inter-module synchronization. Additionally, use of the CC-Link IE Field Network realizes network-level synchronization, providing node-level synchronization that ensures deterministic data flow void of any influence from data transmission delays. This is ideal for applications such as "cutting and folding" inside an offset printer, which requires synchronization between the printing quality sensor, high-speed rotary cutter, folding roller and conveyor.
