Features of PLC

By adopting the global standard open protocol (CIP), seamless data flow between control lines and information monitoring lines can be achieved in a single network system.
EtherNet/IP and DeviceNet tools have unified operability.
The tools used for configuring, monitoring, diagnosing and transferring programs to DeviceNet and EtherNet/IP devices can be run remotely using the same operations.
Safety systems can be monitored.
The safety system can be monitored from the PLC side by combining an EtherNet/IP coupler unit and a slice-type safety control unit.
The convenience of universal Ethernet at your fingertips.
High-capacity communication via high-speed, high-capacity bus.
All data, from interlock information between processes and manufacturing recipes to production data, can be exchanged quickly and at the optimal timing.
Using an Ethernet switch, free wiring and expansion is now possible.
The entire network will not go down due to an abnormality in the communication path, and high-performance network performance and security can be ensured.
Nodes can be detached during operation, ensuring high maintainability by enabling detection, isolation, and recovery of abnormalities.
Unpredictable delays caused by data collisions are minimized.
The impact of wiring abnormalities is minimized on a line-by-line basis.
Reduces network installation and wiring costs.
A general-purpose LAN cable can be used.
For LAN cables, metal cables of Category 5, 5e or higher can be used.
A general-purpose RJ-45 connector can be used.
Since it is a general-purpose Ethernet, standard wireless LAN can be used.
There is no need to rewire when changing the layout.
EtherNet/IP can be made wireless using standard wireless LAN.
Realizes network integration of control and information from the upper level to the field level on Ethernet.
