For example, if you expand the MNET.DATA controller tag structure, you will see
that it contains two controller tag arrays, MNET.DATA.ReadData and
MNET.DATA.WriteData, which are 600-element integer arrays by default.

Each controller tag in the Add-On Instruction is commented in the Description
column.

Notice that the Data Type column displays the data types used to declare each
controller tag, controller tag array or controller tag structure. Individual controller
tags are declared with basic data types, such as INT and BOOL. Controller tag
arrays are declared with arrays of basic data types. Controller tag structures are
declared with user-defined data types (UDTs).
