TON Type Timing function
Illustration
Operation The output is true when input I1 has been true for a time equal or longer than input
I2. The output is false when the input is false.
Values on display: True = -1, false = 0.
Connections Input I1: Boolean value
Input I2: 24 bit integer value (23 bits + sign). 1 corresponds to 1 ms.
Output (O): 24 bit integer value (packed boolean)
TRIGG
Type Timing function
Illustration
Operation The rising edge of input I1 sets the output bit 0 for one program cycle.
The rising edge of input I2 sets the output bit 1 for one program cycle.
The rising edge of input I3 sets the output bit 2 for one program cycle.
