6.6 TP(_E)
Outline
This function block keeps ON a signal for specified duration.
1. Format
*1. Refer to caution points.
2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
When a device specified in turns ON, this function block turns ON a device specified in , and keeps
it ON for duration specified in .
The elapsed time while a device specified in remains ON is set to a device specified in .
A device specified in turns OFF when the elapsed time reaches the set value.
Even if a device specified in turns OFF, this function block does not reset the elapsed time. When a
device specified in turns ON from OFF next time, this function block resets the elapsed time and turns
ON again a device specified in .
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different
from simple projects. Use labels when handling 32-bit data.
You can specify 32-bit counters directly, however, because they are 32-bit devices.
Use global labels when specifying labels.
3) Expression of function blocks in each language
*1. Set the instance when using a function block.
Describe the instance name when programming a function block.
