2. Connect the cable to the hub. Be sure to press in the cable until it locks into
place.
Request cable installation from a qualified professional.
3. Connect the cable to the connector on the Ethernet Unit. Be sure to press
in the cable until it locks into place.
2-6 Creating I/O Tables
2-6-1 I/O Table Overview
I/O tables are used to identify Units mounted to the PLC, and to allocate I/O to
them. With CS-series and CJ-series PLCs, whenever there is a change to the
Unit configuration it is necessary to create I/O tables and register the Units to
the CPU Unit.
The I/O tables can be created in the following ways.
• Using the CX-Programmer offline.
• Using the CX-Programmer online, with the Units mounted to the PLC.
• Using the Programming Console, with the Units mounted to the PLC.
• Using the CPU Unit's automatic I/O allocation at startup. (This method is
available for the CJ Series only.)
From here on, operations involving the Programming Console are
described.
2-6-2 Connecting Programming Devices to the PLC
To create the I/O tables, connect a Programming Device (such as a CX-Pro-
grammer or Programming Console) to the PLC.
