PURPOSE:To change easily a control program or the like after loading, by storing loading information in an external storage device and reading out it by a loading request from a work station or the like and transferring and controlling it. CONSTITUTION:A host processor 1 inputs and processes data from work stations 4-1-4-3 successively and outputs results to stations 4-1-4-3. An external storage device 2 such as a magnetic disc is provided in this host processor 1, and loading information of the control program and etc. used by work stations 4-1-4-3 are stored preliminarily in a storage area 8 of the device 2. Work stations 4-1- 4-3 store said information in RAMs 12-1-12-3 by requests from loading requesting parts 11-1-11-3 and control them. In this case, a work station channel 3 is provided with a loading request indicating part 9 and loading processing part 10; and if said loading information are changed, a down loading request indication is issued to work stations 4-1-4-3 to request reloading, and information of stations 4-1-4-3 are changed. |
