Reading Arrays
To read array data, pass a subscripted array element to ScrDat as the parameter. Also pass a sub-
scripted array element to DstDat as the parameter.
The following example reads the four array variable elements abc[3] to abc[6] from the remote Control-
ler and stores the results in array variable elements def[10] to def[13] in the local Controller. The data
type of abc and def is INT. The size of INT data is two bytes, so the value of the read data size vwx is
UINT#8.

'02\192.168.250.2'
UINT#0
'abc[3]'
UINT#4
def[10]
Values of array variable elements abc[3] to abc[6] in remote Controller are assigned to array variable elements def[10] to def[13] in local
Controller.
DstDat[0]=def[10] INT#1234
DstDat[1]=def[11] INT#2345
DstDat[2]=def[12] INT#3456
DstDat[3]=def[13] INT#4567
Values of array variable abc in remote Controller are assigned to array variable def in local Controller.
RcvSize=vwx UINT#8
The size of data that was read, eight bytes, is assigned to variable vwx.
