3.6. Directly Represented Variables
Free channels are the ones which are not linked to a declared I/O variable. IEC1131 TOOLSET
enables the use of directly represented variables in the source of the programs to represent a free
channel. The identifier of a directly represented variable always begins with % character.
Within a toolset program, the directly represented variables are listed on opening the variable dialogue
to type in a variable name, as shown in Figure 45 below.
