• Handling Multi-dimensional Array
Elements for a multi-dimensional array are given in order from the deepest elements. For exam-
ple, the data is read in the following format when
Var is specified for a variable defined with UINT
Var[2][2] .
Data Format
The following data format is used for a BOOL array (using BOOL b[2][3] as an example).
Data Format
• Exceptions When Specifying the Num of Element Field
The following data format is used if a specification is made in the Num of Element field for a BOOL
array. (Refer to
8-4-5 Specifying Variable Names in Request Paths for information on the Num of
Element field.) The status (TRUE/FALSE) is given in order for each element of the BOOL variable.
