[DESIGN PRECAUTION]
!
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 CPU.
Writing data into the "system area" or outputting a signal for "prohibited to use" may cause a
programmable controller system malfunction.

!
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 100mm(3.94inch) or more from each other.
Not doing so could result in noise that may cause malfunction.
