General Up until now, the inputs and outputs in our programs were coded directly withtheir actual address assignments. Global Variables / Data(valid in the entire program)
Local Variables / Data(only valid in one block) be able to program parameter-assignable function blocks and their calls莫re overwritten with undefined values after the associated block is executed莫re retained even after the block is executed be able to declare static variables and apply them in the program be familiar with the purpose of static variables be familiar with the instance model and the multi-instance model know the difference between functions (FCs) and function blocks (FBs) be able to program parameter-assignable functions and their calls be familiar with the purpose of parameter-assignable blocks be able to declare temporary variables and use them in the program be familiar with the purpose of temporary variables Upon completion of this chapter the participant will.
