IP Communications with Windows

In an Industrial PC, both the Controller and Windows have an internal port, by which they can perform
IP communications to exchange data in IP packets over the internal communications network.
Refer to the NY-series Industrial Panel PC / Industrial Box PC Setup User's Manual (Cat. No. W568) for
details on data exchange between Windows and the Controller.

Tag Data Links (Cyclic Communications)
A program is not required to perform cyclic data exchanges with other devices on the EtherNet/IP net-
work. Normally, a connection is started with the target device for each tag set that was created with the
Network Configurator to start communications for tag data links for a built-in EtherNet/IP port. One con-
nection is used per tag set.
Connection Information
• Target IP address
• Target tag set
• Originator tag set
• Packet interval (RPI)
