Trigger Setting
23 Synchronization Control Signal [cnt_trigger_sync.vi]

 

Select to start sampling of counter input with synchronization control signal after start VI is executed

If you want to synchronize the start timing with multiple boards, make settings with this VI at the slave side

 


IN/OUT Terminal layout

 


Input terminal

CntStartMode

Initial value: 4 (synchronous start)

Specify whether to start the counter synchronously at the start of sampling

3: Counter asynchronization start
4: Counter synchronization start

 

CntStartChannelNum

Initial value: 1

Specify the number of channels to count when sampling

It is specified from Ch 0 with consecutive number of channels
For example, if 2 is specified, it becomes Ch 0, Ch 1 setting

This value is used by the driver to set the counter start condition of each channel 

 

ExtSignal

Initial value: 0 (synchronization control signal 1)

[Essential]
Specify the number of the synchronization control signal to be used for sampling start

0 : Synchronization control signal 1
1 : Synchronization control signal 2
2 : Synchronization control signal 3

* In synchronous operation, it is the slave device that selects the synchronization control signal for the trigger setting

* The recommended setting when synchronization control signal is used at start is synchronization control signal 2
