4.
When the initialization is completed normally, return the mode setting changed in step 1 to "Online" and reset the CPU
module.

When the initialization is completed abnormally, check if measures are taken to reduce noise of the programmable
controller system, and perform the initialization again. If it is completed abnormally again, a hardware failure may occur
in a high speed data logger module. Please contact your local Mitsubishi Electric sales office or representative.
Do not use an electric screwdriver when removing the module. Loose the module fixing screws completely to remove the
