6.7 TON(_E)
Outline
This function block turns ON after specified time.
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 after the
time specified in .
The delay elapsed time until a device specified in turns ON is set to a device specified in .
When a device specified in turns OFF, this function block turns OFF a device specified in and
resets the delay elapsed time.
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.
