32.2.5.1 Structure VariableVariables are available for all models of display units. You can use variables without being aware of device addresses.
Variables can be used with modifiers *1 and as arrays *2. When using modifiers, you can access individual bits or bytes in integer variables.

*1 You can use three different types of modifiers: bit modifier, byte modifier, and word modifier. Only integer variables support modifiers.
Specification method: bit -> VariableName.X[0], byte -> VariableName.B[0], word -> VariableName.W [0]
*2 You can specify consecutive memory addresses using arrays with the following variable types: bit, integer, float, and real.
Specification method: VariableName[10]
*3 Multiple variables grouped together are structures. Structure variables include: Timer, Counter, Time, Date, and PID.
