*The type of trigger that can be selected for analog input and analog output varies depending on the device

  Please refer to [Device-specific Setting List]

 

*1 It can be set only with the following bus master type digital device

  PIO-32DM(PCI), DIO-32DM2-PE, DIO-32DM3-PE

 

*2 It can be set only with device that has a Synchronization Control Connector

 

*3 It can be set only with the following counter device with sampling function

  CNT32-8M(PCI), CNT32-4MT(LPCI)

  CNT-3208M-PE, CNT-3204MT-LPE

  CNT-3204IN-USB

 

What is binary value of analog input/output?

For example, if the resolution of analog device is 12 bit, as the operation of the hardware, the voltage width of set range will be divided into 4096 (12Bit), the divided value is called binary value.

Example: If the range is ±10V

The binary value 0 corresponds to -10V, the binary value 2047 corresponds to about 0V, the binary value 4095 corresponds to +10V,

and the voltage difference between the binary values 0 and 1 is about 0.004883V (4.883mV)

 

The voltage value is easy to understand intuitively, but the binary value is directly used by hardware, and there is no calculation error when voltage conversion. So the value is more accurate.

And, current is the same.
