SAFETY PRECAUTIONS
(Always read these instructions before using this equipment.)
Before using this product, please read this manual and the relevant manuals introduced in this manual
carefully and pay full attention to safety to handle the product correctly.
The instructions given in this manual are concerned with this product. For the safety instructions of the
programmable controller system, please read the user's manual of the CPU module to use.
In this manual, the safety instructions are ranked as "DANGER" and "CAUTION".
! DANGER
! CAUTION
Indicates that incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions,
resulting in medium or slight personal injury or physical damage.
Note that the ! CAUTION level may lead to a serious consequence according to the circumstances.
Always follow the instructions of both levels because they are important to personal safety.
Please save this manual to make it accessible when required and always forward it to the end user.
[Design Precautions]
! DANGER
For details on the operating status of each station when a communication abnormality occurs in
the data link, see the manual for each data link. Erroneous outputs and malfunctions may lead
to accidents.
Not doing so can cause an accident due to false output or malfunction.
To prevent malfunctions of the programmable controller system that may be caused by illegal e-
mails from the outside, take a proper countermeasure (such as virus detection) so that illegal e-
mails are not received by the mail server of this module.
If it is necessary to ensure the security of the programmable controller system against
unauthorized access from external devices via the Internet, appropriate measures must be
incorporated by the user.
Then controlling a running programmable controller (modifying data) by connecting peripheral
devices to the CPU module or connecting a personal computer to the intelligent function
module, configure an interlocking circuit in a sequence program so that the safety of the overall
system is always maintained. Also, before performing other control operations (program
modifications and operation status modifications (status control)) on the running programmable
controller, be sure to read the manual carefully and thoroughly confirm the safety.
Especially in the above mentioned control operations that are performed from an external device
to a remote programmable controller, any problems on the programmable controller side may
not be dealt with promptly due to abnormal data communication. In addition to configuring an
interlocking circuit in a sequence program, determine how the system handles data
communication abnormalities, etc. between the opposite devices and the programmable
controller CPU.
