Event Setting
③ Hardware Event Setting [cnt_event_hw.vi]

Select to set hardware event of counter device

IN/OUT Terminal layout

Input terminal

[Essential]
Specify the channel number for setting the hardware event

Specify the pulse width of the one-shot pulse to be output by a hardware event such as count match
In the sampling function type and other devices, the setting range and pulse width are different

- In the case of a type with sampling function counter device

- For counter devices other than type with sampling function

When this setting is made, signals can be output to the outside depending on the status of the counter device

Hardware events that output control signals are specified in a two-element cluster

■ Element 1: Output event type (EventType)

 Specify the event source that outputs the control signal with five Boolean values
  Any one or more of the factors can be set to True

 When all factors are False, the control signal output terminal can be used as a general-purpose output

  * In the initial state, all factors are False and it is used as general output

■ Element 2: Output signal logic (OutputLogic)

  Specify the output logic of the control output signal

0: Negative logic
1: Positive logic

  * General purpose output can be executed with "Write - ① Digital output (1 bit)"
    At that time, specify the channel number for DoBit

When this setting is made, the count value can be automatically changed at the timing of the count match
Hardware events of count matching are specified in a two-element cluster

■ Element 1: Count match event type (EventType)

  Specify the hardware event to be executed at count match

  * In the initial state, the event designation is invalid, and the count matching hardware event is not performed

■ Element 2: Compare register number (RegisterNo)

  Specify the compare register number to perform count match

  Setting range: 0 or 1

When this setting is made, the counter can be controlled by signal input from the outside to the counter device
Hardware events for control signal input are specified in a three-element cluster

The selection of the processing elements 1 (EventType), component 2 and component 3 (RF0, RF1) is set to accompanying

■ Element 1: Input event type  (EventType)

  Specify the hardware event to be executed by inputting the control signal

  * In the initial state, no hardware event is performed, but it is used as general purpose input

 Counter start/stop case
 Start with the condition of RF0 , stop with the condition of RF1 .

 -  In case of count value preset

     Preset with the condition of　RF0

 - When the count value is cleared to zero

     Clear to zero with the condition of RF0

■ Element 2: Control input trigger edge 0 (RF0)

■ Element 3: Control input trigger edge 1 (RF1)

 Specify the direction of control signal input to execute processing specified by element 1 (EventType)

0: Do not execute
1: Run at the rising edge (Execute at the timing when the input signal changes from Low to High)
2: Executed at the falling edge (Executed at timing when the input signal changes from High to Low)

 Please specify 0 for general purpose input or when setting of RF1 is unnecessary

  * General purpose input can be executed with "Read - ① Digital input (1 bit)"
    In that case, please specify the channel number for DiBit
    Moreover, it is also possible to read all channels collectively with "read - ② digital input (1 port)"

Specify the preset value to use when presetting with hardware event

Setting range: 0~4,294,967,295  (FFFFFFFFH)

This setting is used only when a hardware event condition is satisfied
 If you want to change the count value immediately, perform counter presetting of "Write"
