Parameterized Blocks and Local Data Parameterized blocks support the use of %P global data. Parameterized blocks do not have their own %L data, but instead inherit the %L data of their calling blocks. Parameterized blocks also inherit the FST_EXE system reference and “time stamp” data that is used to update timer functions from their calling blocks. If %L references are used within a parameterized block and the block is called by _MAIN, %L references will be inherited from the %P references wherever encountered in the parameterized block (for example, %L0005 = %P0005). Note: It is possible, by using Test and Edit in the programming software to cause a parameterized block to use %L higher than allowed because of the way it inherits data. Using a word-for-word change to restore this reference to a valid address does not correct the block because the variable still exists in the variable list. Deleting the variable from the variable list does not cause an update to the CPU, so the parameterized block still sees the reference out of range fault. To correct this condition, you must remove the unused variables from the variable list after deleting them from the logic
