Array Specifications for Instances
Array specifications can be made for instances. You can indirectly specify an array element number
with a variable to execute multiple instances with one instance name. Furthermore, you can switch
input sources and output destinations and effectively execute multiple instances with a single
instance name if you use an array specification for the input parameter and output parameter and
specify the element numbers with the same variable.
Example:

Here, array variables are
used to specify instances of
the function block definition
TON and all input parameters
and output parameters. All of
the element numbers are
incremented to execute five
instances in succession.
