How to use structures
To use a structure, register a label using the defined structure as the data type.
To specify each member in a structure, add the member name after the structure label name with a period '.' as a delimiter in
between.
Ex.
Specifying a member in the structure
stLabel1 . bLabel1
Member name
Structure label name
When using double word [unsigned]/bit string [32 bits], double word [signed], double-precision real number
data types in structures, make sure that even number devices are used in all members that use those data
types.
Structure arrays
A structure can also be used as an array.
Structure label [1]
Member (label 1)
Member (label 2)
Member (label 3)
Member (label 4)
When a structure is declared as an array, add an index enclosed by "[ ]" after the structure label name.
Ex.
Specifying an element of a structure declared as an array
stLabel1 [0] . bLabel1
Member name
Index
Structure label name
Data types that can be specified
Primitive data types can be specified as structure members.
When using double word [unsigned]/bit string [32 bits], double word [signed], double-precision real number
data types in structures, make sure that even number devices are used in all members that use those data
types. Depending on the member contents, a member may have to be added for adjusting to even numbers.

dLabel1
dLabel2
wLabel1
wDummy1
dLabel3
dLabel4
