then start communications using the following procedure.
2-4-1 Creating I/O Tables for the Master Unit
I/O tables must be created in the CPU Unit to distinguish between the different
Slaves mounted to the PLC. Turn ON the PLC to which the Master Unit is
mounted, connect the Peripheral Devices to the PLC, and create the I/O
tables. After the I/O tables have been created, turn OFF the power to the PLC.
The following example shows the procedure for creating I/O tables using a
Programming Console. For details on creating I/O tables, refer to the opera-
tion manual for the Peripheral Device being used.
