[DESIGN PRECAUTIONS]
DANGER
Do not write data into the "system area" of the buffer memory of intelligent function modules. Also,
do not use any "prohibited to use" signals as an output signal to an intelligent function module from
the programmable controller CPU.
Writing data into the "system area" or outputting a signal for "prohibited to use" may cause a
malfunction of the programmable controller system.
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 100 mm (3.94 inch) or more from each other.
Not doing so could result in noise that may cause malfunction.
