Processing details
■Operation processing
Turns ON (d1) when (s) is turned ON.
Turns OFF (d1) when (s) is turned from ON to OFF after the elapse of the time set to n. Elapsed time until (d1) is turned OFF
is set to (d2).
When (s) is turned ON again, (d1) turns ON and the elapsed time is reset.
• TOF(_E)
Uses a low-speed timer to count the elapsed time.
Output time can be set between 1ms and 1000ms. The unit is set in Timer limit setting on the PLC system of PLC parameter.
Valid setting range for n is T#0ms to T#3276700ms.
• TOF_HIGH(_E)
Uses a high-speed timer to count the elapsed time.
Output time can be set within the following range. The unit is set in Timer limit setting on the PLC system of PLC parameter.
CPU module
Basic model QCPU, High Performance model QCPU, Process CPU, Redundant CPU
Universal model QCPU, LCPU
Valid setting range for n is T#0ms to T#327670ms.
