Product Features

Compatibility

Use existing Q Series modules
Conventional Q Series modules are compatible with the Universal model QCPU Series. Therefore, when requiring an upgrade, system maintenance costs of existing systems can be kept to a minimum with little disruption when changing over.

*1: The Q00UJCPU is all-in-one type, with integrated power supply, 5-slot base unit, and CPU.

Use existing Q Series programs
Conventional QCPU programs can be used just by changing the PLC type^*2 within the programming tool, which enables easy upgrade to the Universal model Series with little reengineering required.

*2: Depending on the program, the number of steps may vary when the PLC type is changed.

Automatically backup critical data

Programs and parameter files are automatically backed up to the program memory (Flash ROM) which does not require battery backup. This prevents loss of program and parameter data owing to failure in battery replacement. Also, back-up of important data such as device data can be registered to the standard ROM in order to prevent data loss due to a flat battery in case of planned outage during consecutive holidays. The backup data is restored automatically when the power is restored.

Shorten system down recovery time

CPU module change function^*3
The CPU module change function allows the user to create a comprehensive backup of all CPU information to a memory card. In the unlikely event of a CPU failure or other catastrophic event, the backup data can be used to quickly program a new CPU module.
Using this function, the system can rapidly be made operational and downtime can be minimized.

*3: Not supported by Q00UJ, Q00U and Q01U.

Serial numbers

Serial numbers can be checked quickly without having to remove them from the base unit (No interruption of operation is necessary).
Also, serial numbers may be checked using the “product information list” feature included in GX Developer and GX Works2.
