Overview

iQ-R Concept

Key Benefits
• 0.98 ns execution speed improves machine response for faster, more accurate applications
• Multi-discipline control with up to 4 CPUs in a single rack and a high speed bus allow for synchronized data communication between process, motion, and sequential control
• GX Works3 programming software with built-in functions and configuration screens reduces development and troubleshooting time
• CC-Link IE Field network with deterministic performance over industrial Ethernet improves machine response and I/O synchronization
• Built-in SD memory card database provides recipe and data logging
functionality without the need for an external server
• Enhanced security features to protect intellectual property as well as plant safety

Internal Database

The CPU includes an internal database that can be installed into the SD memory card. This allows a selection of database commands that can add/delete/change records to be utilized for simple recipe functions. It is also easy to import/export Unicode files for use in spreadsheets. This is useful where multiple product variations are produced using the same machine process.

High Speed and Synchronization

The iQ-R boasts a high speed system bus for synchronized data communications between multiple CPUs. This improves performance and accuracy, especially for high speed motion control applications. CC-Link IE Field provides deterministic performance over Industrial Ethernet ensuring synchronization between nodes.

Enhanced Security Features

iQ-R has a variety of security features to protect intellectual property and plant safety. Engineers can restrict access at the network level using IP filtering, lowering the risk of hacking or any other unauthorized third party access. At the controller level, security key authentication prevents unauthorized access to the program or execution of the CPU. Security keys can be registered to specific CPUs, personal computers, or an extended SRAM cassette. Use of an SRAM cassette enables CPU replacement in the field without the need for program changes.

Product Lineup

CPU
Programmable automation controllers catering for various different applications.

Base unit
For installing devices such as power supply, CPU and input/output modules. Various base units are available to suit multiple system requirements.

Power supply
This module is used for providing the electrical power for the CPU, input, output, and other modules on the base unit.

I/O module
Devices such as switches, indicator lamps, and sensors can be easily connected to the control system using the digital I/O modules.

Analog I/O module
Analog modules are the main interface between the control process and the automation system, and are specifically designed to interface with sensors that process varying voltage and current signals.

Motion, Positioning, High-speed counter
Distinct set of high-accuracy and fast control response intelligent modules that are ideal for applications requiring high-speed and precision.

Information/network module
This module group enables information exchange with multiple control systems. The module lineup improves production efficiency by collecting and controlling various production information.

Recorder module
The recorder module is a dedicated logging module for system recorder which collects all data per controller scan prior to and after an error event together with a time-stamp.
