■Descriptions, types, and data types
Argument Description
EN Execution condition (TRUE: Execution, FALSE: Stop)
s(IN) Output start
n(PT) Output time setting value
ENO Output status (TRUE: Normal, FALSE: Abnormal)
d1(Q) Output
d2(ET) Elapsed time
Processing details
■Operation processing
1.
Output
• When (s) turns on, (d1) turns on for the time specified by (n). The elapsed time from when (d1) is turned on is set for (d2).
• The timer device is used for counting the elapsed time.
2.
End of output
• (d1) turns off when the elapsed time reaches the set value.
• If (s) is off after (d1) is turned off, the elapsed time is reset.
• Even if (s) is turned off when (d1) is on, (d1) is not turned off.
3.
Setting of output time
The effective setting range of (n) is from 0 ms to 32767 ms. For TP(_E), the output time value of (n) is set in units of 100 ms or
more. For TP_10(_E), it is set in units of 10 ms or more.
The value of when (d1) is turned on from off (rising edge) is used for the setting value of (n). If the value of (n) is changed
while (d1) is on, the changed value becomes valid at the next output start.
