Page 3 SAFETY PRECAUTIONS (Read these precautions before using.) Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full attention to safety to handle the product correctly. The instructions given in this manual are concerned with this product only. For the safety instructions of the programmable controller system, please read the user's manual of the CPU module used.
Page 4 [DESIGN PRECAUTIONS] CAUTION Do not install the control lines and/or communication cables together with the main circuit or power cables, and also do not bring them close to each other. Keep a distance of 100mm (3.94 inch) or more between them. Failure to do so may cause a malfunction due to noise.
Page 5 [WIRING PRECAUTIONS] CAUTION Always ground the FG terminal to the protective ground conductor. Failure to do so may cause a malfunction. Verify the rated voltage and pin-out, and connect the external power supply cable properly. Connecting a power supply with a different voltage rating or faulty wiring may cause a fire or failure. Terminal screws must be tightened with the specified torque.
Page 6 [STARTUP/MAINTENANCE PRECAUTIONS] CAUTION When using a wireless communication device such as a mobile phone, keep a distance of 25cm (9.85 inch) or more from the programmable controller in all directions. Failure to do so may cause malfunctions. Be sure to shut off all phases of the external power supply used by the system before mounting or removing the module.

Page 23 OVERVIEW (d) Automatic transfer is available between link devices of the CC-Link IE controller network module and devices of a CPU module. (Link refresh) For the Universal model QCPU, the extended link register (W) is useful for transferring link register (LW) data that exceeds the link register (W) capacity (8K points).
Page 24 OVERVIEW (g) Cyclic transmission is available only to any specific stations. (Group cyclic transmission function) A Universal model QCPU can share cyclic data with stations in the same shared group. This function is useful, for example, when sharing data among all stations that integrates and controls production lines and not sharing the data with stations that controls other machines.
Page 25 OVERVIEW (2) Communications with other stations' programmable controllers and CC-Link IE controller network compatible devices (Transient transmission) (a) By using a link dedicated instruction, data can be read from or written to a programmable controller on another station. Note that communications with programmable controllers on other networks are also available.

Page 31 OVERVIEW (5) Network diagnostics with GX Developer The network status or each station's operating status can be checked by the CC IE Control Network Diagnostics. By using this, even if an error occurs at system startup or during operation, troubleshooting can be done easily. OUT-side cable disconnection Control station...
Page 32 OVERVIEW (6) Redundant system construction is available. (Compatibility with redundant CPUs) (a) System redundancy using CC-Link IE controller network modules can be designed. By mounting a CC-Link IE controller network module to each of base units with redundant CPUs, a redundant system can be configured. If an error occurs in the control system CPU or CC-Link IE controller network module, the control and standby systems will be switched each other, and the standby system will take over the system control and data link.
Page 33 OVERVIEW (7) Common project data can be created for normal stations For Universal model QCPUs, the station No. of a normal station (own station) can be set in the sequence program. If there are any normal stations that can share the same sequence program and network parameters (except for station No.), specifying their station numbers in the sequence program creates common project data for them, allowing easy data management.
