• Check the free space of the destination to save.
• Check the media of the destination to save.
Retry (e.g. Start monitoring, Connection settings) after checking
the following.
• Check if the target C Controller module is operating.
• Check if the Ethernet cable is connected.
• Check if the specified IP address or host name is correct.
• Using the C Controller setting utility, change the priority setting
of the utility communication task to a smaller value or default.
( Section 9.2.6 (2)(d))

• Increase the free space of the standard ROM, and write the
parameters again.
• Check if the standard ROM has been shut down (MODE LED
is flashing green). If it has been shut down, restart the C
Controller module, and then write the parameters again.
• Check the C Controller module for a hardware fault.
Execute monitoring after setting the No. of monitored modules to
"1-4 modules", or mounting 5 or more CC-Link modules on the
base unit.
Check the data link operating status on the <<Module
information>> tab and then execute again.
Change the logical station No. within the range of 65 to 239.
Check the data link operating status on the <<Module
information>> tab and then execute again.
