[DESIGN PRECAUTIONS]

DANGER
If a communication error occurs in the network, the error station (MELSEC-ST system) shows
the following behavior:
All outputs turn OFF. (In the MELSEC-ST system, the output status at the time of error can be
set to clear/hold/preset by user parameters of each slice module. As "clear" is set by default,
the outputs turn OFF when an error occurs. In the case where the system operates safely with
the output set to "hold" or "preset", change the parameter settings.)
Create an interlock circuit on the program so that the system operates safely based on the
communication status information. Failure to do so may cause an accident due to faulty output
or malfunction.
Create an external fail safe circuit that will ensure the MELSEC-ST system operates safely,
even when the external power supply or the system fails.
Accident may occur due to output error or malfunction.
(1) The status of output changes depending on the setting of various functions that control the
output. Take sufficient caution when setting for those functions.
(2) Normal output may not be obtained due to malfunctions of output elements or the internal
circuits. Configure a circuit to monitor signals whose operations may lead to a serious
accident.
