SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle
the product correctly.
The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable
controller system, refer to the user's manual for the CPU module used.
In this manual, the safety precautions are classified into two levels: "
WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to serious
consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future reference.

[Design Precautions]
WARNING
●
Configure safety circuits external to the programmable controller to ensure that the entire system
operates safely even when a fault occurs in a personal computer. Failure to do so may result in an
accident due to an incorrect output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting
operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured
external to the programmable controller.
(2) The station to which the board is installed may be disconnected from the data link due to a data
link error. If this occurs, the data output from the station and written to other stations before the
error will be held until the station is reconnected to the network (until its data link is
restarted).Provide a mechanism for data link status monitoring and error handling for each station
that is connected to the data link system.
●
For the operating status of each station after a communication failure, refer to this manual. Incorrect
output or malfunction due to a communication failure may result in an accident.
●
When changing data during operation, configure an interlock circuit in the program to ensure that the
entire system will always operate safely. And determine corrective actions to be taken between the
personal computer and CPU module in case of a communication failure.
CAUTION
●
Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to
noise.
WARNING
Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION
Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.
