PURPOSE:To unify a program, even if each unit of many function levels exists, and to easily manage the program by providing a function level setting such as a switch, etc., on each unit being a control object, and executing the control of each unit corresponding to its function level from its set contents. CONSTITUTION:The function of each unit U1, U2 and U3 is changed due to various reasons such as the addition of the function caused by the specification change of a machine, and the modification for improving the performance of the machine, etc., and to which change level (a function related to its change level is called 'a function level') its unit belongs is discriminated by reading the set contents of a switch 4 by a control part 1. As for the switch 4, the dip switch of plural bits is sued, and by setting in advance a code for showing its function level by this switch 4, a function processing program related to its function level is started automatically, and its unit can performs a prescribed function. |
