Features of PLC

The increased CPU capacity allows for ample component control. Data transmission efficiency between the CPU unit and high-performance units has been doubled.
Suppression of variation in cycle time during data processing.
By providing a mode that processes instruction execution and peripheral services in parallel, we have achieved overall balanced high-speed performance.
Supports EtherNet/IP, enabling high-speed, large-capacity data links between PLCs.
CompoNet compatibility accelerates wiring reduction, computerization, and standardization of equipment. DeviceNet compatibility enables flexible system construction.
Enhanced Ethernet compatibility with support for a wide range of functions.
We respond to the need to create communication systems that span multiple layers, from network to network, and can handle a wide range of systems, from small to large.
The duplex system improves the reliability of facilities and equipment.
The hot standby system is used for CPU unit duplication.
Units can be replaced online with online replacement operation while the power is on and the unit is running.
You can select a redundant or standalone configuration for the CPU unit, power supply, and communications.
Controller Link enables network duplication between PLCs.
