string in the PLC tags editor.
You can specify the maximum string size in bytes by entering square brackets after the
keyword "String" (once the data type "String" is selected from a data type drop-list). For
example, "MyString String[10]" would specify a 10-byte maximum size for MyString. If you do
not include the square brackets with a maximum size, then 254 is assumed.
The following example defines a String with maximum character count of 10 and current
character count of 3. This means the String currently contains 3 one-byte characters, but
could be expanded to contain up to 10 one-byte characters. ASCII control characters can be used in Char and String data. The following table shows
examples of control character syntax. You can create an array that contains multiple elements of the same data type. Arrays can
be created in the block interface editors for OB, FC, FB, and DB. You cannot create an array
in the PLC tags editor.
To create an array from the block interface editor, name the array and choose data type
"Array [lo .. hi] of type", then edit "lo", "hi", and "type" as follows:
● lo - the starting (lowest) index for your array
● hi - the ending (highest) index for your array
● type - one of the data types, such as BOOL, SINT, UDINT Value limits: -32768 to +32767
 Valid: Mixed constants and variables
 Valid: Constant expressions
 Not valid: Variable expressions You can use the data type "Struct" to define a structure of data consisting of other data
types. The struct data type can be used to handle a group of related process data as a single
data unit. A Struct data type is named and the internal data structure declared in the data
block editor or a block interface editor.
Arrays and structures can also be assembled into a larger structure. A structure can be
nested up to eight levels deep. For example, you can create a structure of structures that
contain arrays.
A Struct variable begins at an even-byte address and uses the memory to the next word
boundary.
4.4.8 PLC data type
The PLC data type editor lets you define data structures that you can use multiple times in
your program. You create a PLC data type by opening the "PLC data types" branch of the
project tree and double-clicking the "Add new data type" item. On the newly created PLC
data type item, use two single-clicks to rename the default name and double-click to open
the PLC data type editor.
You create a custom PLC data type structure using the same editing methods that are used
in the data block editor. Add new rows for any data types that are necessary to create the
data structure that you want.
If a new PLC data type is created, then the new PLC type name will appear in the data type
selector drop drop-lists in the DB editor and code block interface editor.
Potential uses of PLC data types:
● PLC data types can be used directly as a data type in a code block interface or in data
