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.
