3-26 Functional Blocks
OR
PULSE
Description Provides an up to 8-input OR algorithm, meaning that it performs the inclusive OR Boolean function. Each input (IN [1],
IN [2], ..., IN [8]) has the capability of being optionally inverted, if required.
Function Turns the digital output (OUT) ON if any one input (IN [1], IN [2], ..., IN [8]) is ON; therefore:
If all inputs are OFF, then: OUT = OFF.
If any one input is ON, then: OUT = ON.

Inputs IN [1..8] = Boolean value
Outputs OUT = Boolean value controlled by the status of input signals.
Parameters IN [1..8]
INPTINVSTS [1..8]
Description Provides a fixed pulse output (OUT) each time the input (IN) transitions from OFF to ON. You specify the fixed output
pulse width (PULSEWIDTH) in seconds through configuration.
Function Used to define the fixed output (OUT) pulse width.
• If the input (IN) pulse time is less than or equal to the fixed PULSEWIDTH time, output (OUT) pulse width equals
the fixed PULSEWIDTH time.
• If the IN pulse time is greater than the fixed PULSEWIDTH time, OUT pulse width is restricted to the fixed
PULSEWIDTH time. Another output pulse cannot be generated until the preceding pulse has completed.
Inputs IN = Boolean value
Outputs OUT = Boolean value
Parameters IN
ORDERINCM
OUT
PULSEWIDTH
