When communicating with the C series, set the addresses from the PLC to store the setting
item data of the C series after the power supply to the PLC is turned on.
Communication is impossible if the addresses for storing the setting item data of the C series
are not set.
Set the program referring to the sample program (Fig.8.2-1) as follows.
(Execute only the first scan of the following sample program.)
Note
Leave file memory addresses (DM0000 to DM0002) of the PLC vacant when setting the program
since the addresses (DM0000 to DM0002) are used for the top address for the temperature control.
