PROBLEM TO BE SOLVED: To prevent duplicated input work of a worker by feeding an NC data constantly from a data management computer to the first memory means of each programmable controller and transferring the NC data from the first memory means to a second memory means when the type of commodity is altered and then operating a multi-commodity production system. SOLUTION: A data management computer 1 is connected with a plurality of programmable controllers 4 each equipped with first and second memory means 21, 22. The first memory means 21 is constantly fed with an NC data which is transferring from the first memory means to a second memory means when the type of commodity is altered thus operating a multi-commodity production system 6. According to the system, duplicated input work of a worker can be eliminated and the work time for inputting the input parameters can be shortened at the time of changing the arrangement. |
