For the parameter setting method, see the manual of the programmable
controller CPU to be used.
When the GX Works2 or GX Works3 cannot connect with the Programmable
Controller CPU, check for problems in the settings of the GX Works2 or GX
Works3 .
For the parameter setting method, see the manual of the programmable
controller CPU to be used.
When the GX Works2 or GX Works3 and Programmable Controller CPU are
connected via Ethernet, check the details of the Ethernet diagnosis error, and
then remove the cause of the error.
The following table shows the default values when the C Controller module or
C intelligent function module has been initialized.
IP address (CH1): 192.168.3.3

For the initialization method, refer to the manual of the C Controller module or
C intelligent function module.
The pre-installed SECS/GEM communication software license is erased when
the C Controller module or C intelligent function module has been initialized.
When Setting/monitoring tools for the C Controller module cannot connect
with the Programmable Controller CPU, check for problems in the settings of
