[DESIGN PRECAUTIONS]
DANGER
z Do not write data to the "System Area" in the intelligent function module's
buffer memory. Also, do not turn the output for signals for "Use Prohibited"
signals among the output signals from the PLC CPU to the intelligent
function module (ON).If data are written to the "System Area" or output in
response to "Use Prohibited" signals, there is danger that the PLC system
will malfunction.

CAUTION
z 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 (3.94 in.) or more from each other. Not doing so could result in noise
that may cause malfunction.
z If a BASIC program is registered in the EEP-ROM in the module, do not
perform a power OFF or PLC CPU reset operation at the station where the
module is installed during registration. If a power OFF or PLC CPU reset
operation is performed at the station where the module is installed during
registration, the data contents in the EEP-ROM will be indefinite and it will be
necessary to reset the setting values, etc. in the buffer memory and register
them again in the EEP-ROM. It could also cause the module to break down
or malfunction.
[INSTALLATION PRECAUTIONS]
CAUTION
z Use the PLC in an environment that meets the general specifications
