Retrieval of Setup Data and Configuration
Program Example 2
This program executes the following two items. This program contains both items,
but each item can be written and executed separately.
• Retrieval of setup data
• Setting a DC voltage range to the channel
Public Function Main()
Dim line As String * 256
'connect
host = "192.168.1.11"
comm = openDARWIN(host, rc)
'get
rc = talkOperationDataDARWIN(comm, 0, 1, 0, 2)
Do
rc = getSetDataByLineDARWIN(comm, line, 256, lenLine,
flag)
Loop While (flag And DAQDARWIN_FLAG_ENDDATA) = 0
'range
rc = setVOLTDARWIN(comm, DAQDARWIN_RANGE_VOLT_20MV, 0, 1, 2,
0, 0, 0, 0, 0)
'disconnect
rc = closeDARWIN(comm)
End Function
Description
Talker
talkOperationDataDARWIN(comm, 0, 1, 0, 2)
Specifies the type of setup data to be retrieved (setup data of the operation mode)
and the channel range (channels 1 and 2 of subunit number 0).
Retrieval of Setup Data
getSetDataByLineDARWIN(comm, line, 256, lenLine, flag)
Gets the output by the talker function line by line in a 256-byte field.
The end is determined by the flag status of “end data.”.
Setting a DC voltage range to the channel
setVOLTDARWIN(comm, DAQDARWIN_RANGE_VOLT_20MV, 0, 1, 2, 0, 0,
0, 0, 0)
Sets the measurement range of channels 1 and 2 of subunit number 0 to 20 mV.
The scaling function is not used.
The constant 20 mV is used to specify the range type.
