2 Preparations before Operating
Ethernet connection
This section explains how to connect the controller and PC using an Ethernet connection. An
Ethernet connection allows connection of multiple controllers to a single PC. The
communication protocol is TCP/IP, and the connection format is Peer to Peer.
• Be sure not to use duplicated IP addresses for the controller(s) and PC.
• KEYENCE does not guarantee the operation of connections using other LAN protocols or routers.
• It is not possible to operate more than one controller simultaneously from a single PC.
• It is not possible to operate one controller simultaneously from multiple PCs.
Connection
1
Connect a commercially Ethernet cable (crossover cable, category 5) to the Ethernet
port on the controller.
2
Connect the other end of the cable to the LAN port on the PC.
„ Connecting two or more controllers
You will need a hub that supports 100BASE-TX or 10BASE-T.
For the connection between the controller and hub, or between the PC and hub, use a
commercially available straight Ethernet cable.
