LOGIC VARIABLES
Logic variables entered in equation form control the actual relay outputs. Names assigned to the inputs,
timers, and outputs represent these variables in the equations. Table 5-1 lists the variable names and
what they represent. Figure 5-1 illustrates the logic variables in the form of function modules.
