CAUTION
Do not install the control lines or communication cables
together with the main circuit or power lines, or bring them
close to each other.
Keep a distance of 100mm (3.94inch) or more between
them.
Failure to do so may cause malfunctions due to noise.
If having read register R outside the allowable range with the
MOV instruction, the file register data will be FFFF
H
. Using
this as it is may cause malfunctions. Pay attention not to use
any out-of-range file register when designing sequence
programs. For instruction details, refer to the programming
manual.
When an output module is used to control the lamp load,
heater, solenoid valve, etc., a large current (ten times larger
than the normal one) may flow at the time that the output
status changes from OFF to ON. Take some preventive
measures such as replacing the output module with the one
of a suitable current rating.
