Meaning Explanation
0.05s
• This relay repeatedly turns on and off at the
specified interval.
0.1s
• This relay starts with off at power-on or
reset of the CPU module. (Note if the
specified time has elapsed, on/off status
will change even during program
0.5s
execution.)
1s
• This relay repeatedly turns on and off at the
interval specified in SD414 (unit: second).
• This relay starts with off at power-on or
reset of the CPU module. (Note if the
ns
specified time has elapsed, on/off status
will change even during program
execution.)
• This relay repeatedly turns on and off at the
interval specified in SD415 (unit: ms).
• This relay starts with off at power-on or
reset of the CPU module. (Note if the
n(ms)
specified time has elapsed, on/off status
will change even during program
execution.)
• This relay repeatedly turns on and off at the
specified scan intervals.
• This relay starts with off at power-on or
reset of the CPU module. (For the
redundant CPU, however, this relay will
become always off after system switching.)
• The on/off scan intervals are set by the
DUTY instruction.
