1-2 Communications with the Host
1-7
1-2-6 Memory Link Connections
When the host is a computer instead of a PLC, the Memory Link protocol can be used to
connect with the computer. Use serial port A or B to connect to the host. For details, refer to
the Host Connection Manual (Tem.Control, MemLink).
1-2-7 Communicating with Other Devices
The NS-series PTs can communicate with the following devices.
• OMRON Trajexia Motion Controllers
• Mitsubishi FX-series, A-series, and Q-series PLCs
• Siemens S7-300-series PLCs
• Yaskawa MP-series Machine Controllers
• Yaskawa F7-series Varispeed and VS Mini V7-series Inverters
• Rockwell Automation (Allen-Bradley) SLC50, MicroLogix, PLC-5, CompactLogix,
CompactLogix, and ControlLogix Controllers
• Devices that support Modbus RTU
• Yokogawa Electric FA-M3/FA-M3R-series PLCs
For details on connection methods, refer to the Host Connection Manual (Multivendor Con-
nection).
1-2-8 EtherNet/IP
EtherNet/IP is a multi-vendor industrial network protocol that uses Ethernet. The specifica-
tion is an open standard managed by the ODVA (Open DeviceNet Vendor Association), as is
DeviceNet, and it is used for a variety of industrial devices.
NS-series PTs can communicate with CS/CJ-series EtherNet/IP Units and
CJ2H-CPU@@-EIP CPU Units, which have a built-in EtherNet/IP port. Also, it is possible to
perform tag message communications if an NS-series PT is connected to a CJ2H PLC. The
CJ2H-CPU@@-EIP has a tag name server in the CJ2H-CPU@@-EIP Unit, so if a tag name
and address table is stored in advance, it is possible to perform access from the NS-series
PT using only the tag name.
