[DESIGN PRECAUTIONS]
!

DANGER
• Do not write data into the "system area" of the buffer memory of intelligent function modules.
Writing data into the "system area" may cause a programmable controller system malfunction.
• Depending on the malfunction of the external output transistor, there may be cases where the
output is ON or OFF status. Install external monitoring circuitry for out put signals that may lead
to major accidents.

!

CAUTION
• Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 150 mm (5.9 inch) or more from each other.
Not doing so could result in noise that may cause malfunction.
