2 Instruction Descriptions
The data type of UnitProxy is structure _sNXUNIT_ID. The meanings of the members are as follows:
Name
UnitProxy
NodeAdr
IPAdr
UnitNo
Path
PathLength
Pass the device variable that is assigned to the specified Unit to UnitProxy.
The data type of Obj is structure _sNXOBJ_ACCESS. The meanings of the members are as follows:
Name
Obj
Index
Subindex
IsCompleteAc-
*1
cess
*1 This member is not used for this instruction. Always set the value to FALSE.
Notation Example
The following notation example shows how to read the unit version from an NX-ID4342 Digital Input
Unit.
The read data is stored in Rdat, which is a UDINT variable.
A variable that is named 'NX1' with a data type of _sNXUNIT_ID is assigned to the Unit from which to
read the data.
For the NX-ID4342, the index of the Unit version is UINT#16#1000 and the subindex is USINT#6.
