SAFETY PRECAUTIONS
(Read these precautions before using.)
When using Mitsubishi equipment, thoroughly read this manual and the
associated manuals introduced in this manual. Also pay careful attention to
safety and handle the module properly.
These SAFETY PRECAUTIONS classify the safety precautions into two
categories: “DANGER” and “CAUTION”.
DANGER
CAUTION
Procedures which may lead to a dangerous condition and
cause death or serious injury, if not carried out properly.
Procedures which may lead to a dangerous condition and
cause superficial to medium injury, or physical damage
only, if not carried out properly.
Depending on circumstances, procedures indicated by
CAUTION may also
be linked to serious results.
In any case, it is important to follow the directions for usage.
Store this manual in a safe place so that you can take it out and read it
whenever necessary. Always forward it to the end user.
[DESIGN PRECAUTIONS]
DANGER
Do not write data to the "read-only area" in the buffer memory of the
intelligent function module.
Do not turn on/off the "reserved" signals among the I/O signals to/from the
programmable controller CPU.
Doing so can malfunction the programmable controller system.
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 output 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 100 mm(3.94 inch) or more from each other.
Not doing so could result in noise that may cause malfunction.
