19. LOADING AND INSTALLATION
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 register R outside the allowable range has been read out 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.
Time from when the CPU module is powered on or is reset to when it enters in RUN
status depends on the system configuration, parameter settings, and program size.
Design the program so that the entire system will always operate safely, regardless
of the time.
