5.1 Procedure from Parameter Settings to Data Link Startup
The following explains the procedure from setting the parameters to stating the data link.
5.1.1 CPU Parameter Area and Master Module Parameter Memory
(1) CPU Parameter Area
This area is used to set the basic values for controlling the programmable controller system and the
network parameters that control the CC-Link system.
(2) Master Station Parameter Memory
This area stores the network parameters for the CC-Link system.
When the module is powered OFF or the programmable controller CPU is reset, the network
parameters are erased.

and automatic refresh
parameters, which
are then written to the
programmable
controller CPU.

the network parameters
in the programmable
controller CPU are
transferred to the master
station and the data link
is automatically started.
