PREPARATORY PROCEDURES AND SETTING
When a connection to the C Controller module cannot be established although
"192.168.3.3 (default)" is set in Connection settings, check the network settings of
the C Controller module and development environment (personal computer).
( Page 6-39, Section 6.6)
(a) Precautions
1) Flashing "01" or "02" of the 7-segment LED (Q12DCCPU-V only)
At start-up of the C Controller module, "01" or "02" flashes on the 7-segment
LED when the C Controller module is:
• In factory-default state.
(The standard RAM is not initialized.)
• Left unused for a long period of time with no battery installed.
(The standard and battery-backed-up RAM data are corrupted.)
If "01" or "02" flashes on the 7-segment LED, install a battery and perform the
module initialization setting procedure.
2) When having replaced the C Controller module
Restart all connected devices (gateway server, personal computers, etc.)
(If any of these devices retains an Ethernet address of its communication
target, continued communication may be disabled after the replacement
because the Ethernet address is changed.)
Likewise, restart the C Controller module when a target device has been
replaced.

Programming
Operation
1) Create a user program with Workbench or Tornado.
2) Debug the user program.
3) Register the user program to the C Controller module.
4) Back up the standard RAM data not to lose them due to
expiry of battery life. (Q12DCCPU-V only)
