Abstract
PURPOSE: To obtain flexibility to the alteration and addition of system, by writing in the step memory module selection register the memory module number for the steps used from now.
CONSTITUTION: The unit provides the common memory module 5 in common use with a plurality of processing programs according to a plurality of transmission control steps, and a plurality of step memory modules 6 independently stored every step by the specific in the transmission control steps. Further, the address of the module 6 is assigned to the same address area other than the address area of the module 5 and the module selection register 7 is provided. When the program stored in one of the modules 6 is executed, only the module 6 where the program to be executed with the module selection register 7 is stored, is selected. Thus, the flexibility to system addition and alteration can be obtained.
