65 Advanced Features Usage Examples
Using the Scheduled Action Command Feature to Trigger a
Pulse
The following procedure demonstrates how you can configure the action command feature to trigger a
pulse on the
GpioOut0
signal at a scheduled time. You must enable the IEEE 1588 Precision Time
Protocol (PTP) to synchronize the time between the devices on the network.
To configure a scheduled action command
1.
Follow steps 1-5 in the procedure, “To control the PLC remotely” on page 56.
2.
In the TransportLayerControl section, select True in the GevIEEE1588 list.
The GevIEEE1588Statu s shows either Master or Slave .
3.
In the ActionControl section, select ActionTrig0Pulse in the ActionSelector list.
4.
Select ActionDeviceKey and enter 5555 .
5.
Select ActionGroupKey and enter 36 .
6.
Select ActionGroupMask and enter 3 .
7.
In the Timer section, select TriggerInput from the TimerTriggerSource list.
8.
In the TimerGranularityFactor list, select Granularity1p96608ms .
The other settings in the Timer section can remain as the default settings.
9.
In the SignalRouting section, select one of the equations, for example, PlcEquation0 , and enter the
following equation: Timer0Trig = ActionTrig0 .
10.
In the SignalRouting section, select another of the available equations, for example, PlcEquation1 ,
and enter the following equation: GpioOut0 = Timer0Out .
11.
Click PlcEquationApply to apply the equation.
12.
In the TransportLayerControl section, click GevTimestampControlLatch .
GevTimestampValue shows the current timestamp and is used as a reference in step 19 below.
