Counter Input Operation Check

Sample VI folder

  64bit environment: C:\Program Files (x86)\CONTEC\DAQ-LV-WIN for LabVIEW\Samples
  32bit environment: C:\Program Files\CONTEC\DAQ-LV-WIN\Samples

 


Counter input

1. Open MonitorCnt.vi from the CNT folder in the sample VI folder

 

 

2. Enter the device name to use in the "DeviceName" field.
   If the device name confirmed by the device manager is "CNT000" (initial value), you can leave it as it is.

3. Make other settings in the "Channel Setting" column.
   In case of uncertainty please check the commentary etc.

4. Execute VI and input a pulse to Ch0.
   Please confirm that CntData (count value) in "Read" column changes.

   You can also check the signal change of the input terminal in "Status" column.
   The meaning of the symbol in "Status" column of this sample is described.

A: It is the input status of Phase A
B: Input status of Phase B
Z: Input status of phase Z
U: Input status of general-purpose input
D: Indicates the counting direction ([OFF] up count / [lighting] down count)

If you can read the number of input pulses, operation confirmation is completed.
Please press "Stop" button to close VI.

Counter device with sampling function and other counter devices

Our counter devices are roughly divided into two, type with sampling function and others, and functions are different.
Please be aware that there are differences in VIs and samples that can be used with DAQ-LV-WIN.

As of 2024, counter devices with sampling function are the following 5 products.
  CNT32-8M(PCI)
  CNT32-4MT(LPCI)
  CNT-3208M-PE
  CNT-3204MT-LPE
  CNT-3204IN-USB
