3.3.4 Example of a TON Instruction
This logic shows that as long as belt.5 is true
timer2 increments to 1000. When 10 seconds
have elapsed, the timer sets Q true, causing the
variable box to be set true.
3.4 Timer Pulse (TP)
Use this instruction to enable an output for a preset amount of time. This instruction
guarantees that an output remains on for a preset time, regardless of the state of the
EN input.
When EN is true, the instruction sets outputs Q and T and begins counting towards the
preset value. The timer increments regardless of EN's state until the value in Elapsed
equals that of TPreset. When these values are equal, outputs Q and T become false.
The value in Elapsed is reset when EN is false and the value in Elapsed equals that of
TPreset. The value in Elapsed is in increments of 0.01 seconds.
