Controlling the Advanced Features from the Computer
The following procedure demonstrates how you can control the PLC and other advanced features from
a computer, connected to the video interface, using the control bits that make up the remote control
block.
To control the PLC remotely
1.
Connect the hardware as shown in the “PLC Demonstration Example” on page 54.
2.
Start eBUS Player and connect to the video interface.
3.
Connect the voltage indicator or LED assembly to the pin on the circular connector that
corresponds to
GpioOut0 signal on your video interface.
4.
Under Parameters and Controls, click Device control .
5.
Click Guru in the Visibility list.
6.
In the SignalRouting section, select one of the available equations, for example, PlcEquation0 , and
enter the following Boolean equation: GpioOut0 = PlcCtrl0 .
7.
Click PlcEquationApply to apply the equation.
8.
In the ControlBits section of the Plc category, select one of the inputs from the PlcCtrlSelector list,
for example, PlcCtrl0 .
9.
In the PlcCtrlValue list, click True to set the signal state to high, or False to set the signal state to
low.
When PlcCtrl0 is set to True , the output on GpioOut0 shows a high value on the voltmeter or
oscilloscope, and when set to False , it shows a low value.
Using the Timer Feature to add a Pulse to a Signal
The following procedure demonstrates how you can configure the timer to output a continuous 1 Hz
pulse that is high for 0.25 s and low for 0.75 s.
To configure the timer feature to add a pulse to a signal
1. Follow steps 1-5 in the procedure, “To control the PLC remotely” on page 56.
2. In the
Timer
section, select
Timer0
from the
TimerSelector
list.
3. Select
TimerDurationRaw
and enter
8138
to set the length of time that the state of the pulse is
high.
This value represents the number of internal clock ticks.
4. Select
TimerDelayRaw
and enter
24414
to set the length of time that the state of the pulse is low
(the length of time before the signal becomes high).
This value represents the number internal clock ticks.
5. Select
TimerTriggerSource
and select
Continuous
to set an internal triggering source for the timer
and automatically trigger again after emitting the pulse.
6. Select
TimerGranularityFactor
and select
Granularity30p72us
to set the interval of the timer's
internal clock tick.
