Allen-Bradley ProcessLogix 1757 Series - Maxpulse; Min; Minpulse

Publication 1757-RM810A-EN-P - May 2002
Functional Blocks 3-21
MAXPULSE
MIN
MINPULSE
Description Provides a maximum time limit pulse output (OUT) each time the input (IN) transitions from OFF to ON. You specify the
maximum output pulse width (PULSEWIDTH) in seconds through configuration.
Function • Used to limit the output (OUT) pulse to a maximum width.
• If the input (IN) pulse time is less than or equal to the specified PULSEWIDTH time, IN is assumed to equal one
output (OUT) pulse.
• If the IN pulse time is greater than the specified PULSEWIDTH time, OUT pulse terminates at end of specified
PULSEWIDTH time.
Inputs IN = Boolean value
Outputs OUT = Boolean value
Parameters IN
ORDERINCM
OUT
PULSEWIDTH
Description Provides an 8-input MIN function, meaning that it provides an output that is the minimum value of eight inputs.
Function Used to isolate the lowest value of multiple input values and use it as a designated output value. This block ignores
NaN inputs.
Inputs IN [..8] = Real numbers
Outputs OUT = Real number
Parameters IN [1..8]

OUT
Description Provides a minimum time limit pulse output (OUT) each time the input (IN) transitions from OFF to ON. You specify the
minimum output pulse width (PULSEWIDTH) in seconds through configuration.
Function • Used to define the minimum output (OUT) pulse width.
• If the input (IN) pulse time is less than or equal to the specified PULSEWIDTH time, output (OUT) pulse width
equals the specified PULSEWIDTH time.
• If the IN pulse time is greater than the specified PULSEWIDTH time, OUT pulse width tracks IN pulse time, so OUT
pulse exceeds specified PULSEWIDTH time.
Inputs IN = Boolean value
Outputs OUT = Boolean value
