(Process) (Redundant)
• [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 keep the signal on for the specified period of time.

Argument Description
EN Execution condition (TRUE: Executed, FALSE: Not executed)

d2 (ET) Elapsed time
Processing details
■Operation processing
1.
Output
• When (s) turns on, (d1) turns on for the period of time set by (n). The time elapsed after (d1) turns on is set to (d2).
• Use the long timer to count the elapsed time.
2.
End of output
• Once the elapsed time reaches the setting time, (d1) turns off.
• If (s) is off after (d1) turns off, the elapsed time is reset.
• Even when (s) turns off while (d1) is on, (d1) does not turn off.
3.
Output 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 (d1) is used for the setting value of (n). When the (n) value is changed when (d1) is
on, the new value will be enabled at the next output start timing.

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 output time setting value is of time type (32-bit value).
