(Process)
• [RnPCPU (redundant)] If these function blocks are used in a program executed in both systems, they do not operate in the standby system when the
redundant system is in backup mode. ( MELSEC iQ-R CPU Module User's Manual (Application))
These function blocks turn on a signal after the specified period of time.

Output
• When (s) turns on, (d1) turns on after the time that was set by (n). The delay time elapsed after (d1) turns on is set to (d2).
• When (s) turns off, (d1) turns off and the delay elapsed time is also reset.
• Use the long timer to count the elapsed time.

Delay time setting
The valid setting range of (n) is T#1ms to T#2147483ms. Note that the valid setting range will be as follows by changing the
timer limit setting using the engineering tool.
Minimum value
Identical to the long timer setting value [ms] in the timer limit setting.
Note that if the long timer setting value is smaller than 1ms, the
minimum value will be 1ms.
The value at the rising edge (off to on) of (d) is used for the setting value of (n). When the (n) value is changed while (s) is on,
the new value will be enabled at the next rising edge of (s).

Maximum value
The time satisfying the following condition is used.
Note that the maximum value is a value that can be included within the range of time
type because the delay time setting value is of time type (32-bit value).
• Delay time setting value [ms]  2147483647 [ms]  Long timer setting value of in
the timer limit setting [ms]
[Example]
• If the long timer setting value is 0.001ms: T#1ms to T#2147483ms
• If the long timer setting value is 1000ms: T#1000ms to T#2147483000ms
