Title:
LOADING CONTROL SYSTEM FOR CONTROL PROGRAM OF WORK STATION
Document Type and Number:
Japanese Patent JPH01128149
Kind Code:
A
Abstract:
PURPOSE:To extremely shorten the loading time to plural simultaneous requests by storing previously a control program into a main memory and loading the loading requests via a multi-tasking system. CONSTITUTION:All work station control programs are previously stored in a main memory 2 at initialization. When the work station control program loading requests are produced at one time from work stations 9-1-9-3, a work station control mechanism 3 gives a loading execution instruction to a work station control program loading mechanism 7 in the order of acceptance of those requests. Thus the mechanism 7 gives an instruction to a task control processing part 5 to produce a task to perform the loading control of the station 9-1. The part 5 produces a task X. In the same way, the part 5 produces tasks X<0> and Y with reception of due instructions. Then the tasks X and X<0> read the X control program stored in the memory 2; while the task Y reads a Y control program. Then the program loading process is carried out to the stations 9-1-9-3 via the mechanism 3.
