Ptxx – Digital Output, Pulse Width Modulation View

Use Ptxx – Digital Output, Pulse Width Modulation to view or configure the points for the device.
Ptxx – Digital Output, Pulse Width Modulation View Example
The Ptxx – Digital Output, Pulse Width Modulation view includes these parameters:
Parameter
Description
Enable Pulse Width Modulation (PWM)
Determines whether the output is Pulse Width Modulation or Digital Output.
Enforce Duty Cycle at 50.0% for Pulse Train Output (PTO)
Determines whether to enforce the PTO specific duty cycle, which is fixed at 50%. If enabled,
O.Pwmxx.DutyCycle
 is ignored.
Enable Cycle Count Limit
Determines whether to generate a defined number of pulse cycles when there is a rising edge in the data or continuous pulse cycles when data is On.
  • 0 = Pulse cycles continue to occur until
    O.Ptxx.Data
     is set to 0.
  • 1 = Allow only a fixed number of pulse cycles to occur when there is a rising edge in
    O.Ptxx.Data
    .
Execute All Cycles
Only applicable when Enable Cycle Count Limit is enabled.
When
O.Ptxx.Data
 transitions to 0:
  • 0 = Stop generating pulses immediately
  • 1 = Continue generating pules until the Pulse Cycle Limit is reached
Output State when PWM is Idle
Determines the state of the output when PWM is idle.
  • 0 = When PWM is idle, the output is Off. It also means that when PWM is running, the active state per
    O.Pwmxx.DutyCycle
     is the output in On state.
  • 1 = When PWM is idle, the output is On. It also means that when PWM is running, the active state per
    O.Pwmxx.DutyCycle
     is the output in Off state.
Cycle Time
Displays the period in seconds of one pulse cycle.
Duty Cycle
Displays the percentage of the pulse cycle time when the output is in an active state.
Cycle Count Limit
Displays the number of pulse cycles to generate when there is a rising edge in the data.
Only applicable when Enable Cycle Count Limit is enabled.
Output State in Program Mode
Program State
Determines the behavior of each output when the controller transitions to Program Mode or Inhibit mode. While in Program Mode or Inhibit mode, outputs from the controller are ignored and the output behaves as follows:
  • Off – Output is 0 or Off.
  • On – Output is 1 or On.
Output State in Communication Fault Mode
Communication Fault State
Determines what happens to the output of each point after a communication fault occurs and the module enters Communication Fault Mode.
  • Off – Output is 0 or Off.
  • On – Output is 1 or On.
Output State in Communication Fault Mode
Communication Fault State Duration
Determines the length of time the Communication Fault Mode is held before the Final Fault State.
Output State in Communication Fault Mode
Final Communication Fault State
Determines whether the module transitions to On or Off after the Communication Fault Mode Output State Duration elapses. The default final state is Off.
If you choose Forever for Duration, you cannot choose a final state. The module retains its current Communication Fault Mode state.
Output State When Communication Fails in Program Mode
Determines the output action if communication fails in Program Mode.
  • Program Mode – Indicates leaving outputs in Program Mode state.
  • Communication Fault Mode – Indicates changing outputs to Communication Fault Mode state.
Diagnostics
Opens the Diagnostics dialog, which contains diagnostic information.
