[OPERATION PRECAUTIONS]
CAUTION
● Construct an interlock circuit in the program so that the whole system always operates on the safe
side before executing the control (for data change) of the PLC in operation.
Read the manual thoroughly and ensure complete safety before executing other controls (for program
change, parameter change, forcible output and operation status change) of the PLC in operation.
Otherwise, the machine may be damaged and accidents may occur by erroneous operations.
● Do not power off the CPU module or reset the CPU module while the setting values in the buffer
memory are being written to the flash ROM in the intelligent function module. Doing so will make the
data in the flash ROM card undefined. The values need to be set in the buffer memory and written to
the flash ROM again. Doing so can cause malfunction or failure of the module.
● Note that the whole system may not be reset by the RUN/STOP/RESET switch when the CPU module
or intelligent function module detects an error, such as a watchdog timer error, during self-diagnosis.
In such cases, turn the power off and on again.
[DISPOSAL PRECAUTIONS]
CAUTION
● Please contact a certified electronic waste disposal company for the environmentally safe recycling
and disposal of your device.
[TRANSPORTATION PRECAUTIONS]
CAUTION
● The PLC is a precision instrument. During transportation, avoid impacts larger than those specified in
the general specifications of the User's Manual (Hardware) of the CPU module by using dedicated
packaging boxes and shock-absorbing palettes. Failure to do so may cause failures in the PLC. After
transportation, verify operation of the PLC and check for damage of the mounting part, etc.
