Abstract

PURPOSE:To improve the operation efficiency of a production line by judging processing conditions from processing condition data sent from a preprocess and an inquiry to a host computer. CONSTITUTION:The processing conditions are passed from the host computer 1 to a control computer 4 for a 1st process through a network 3 as master data. When the control computer 4 finishes the process, the control computer sends processing condition data for a next process through a message distributing mechanism 2 and the network 3. Then the control computer 4 for the next process sends an inquiry to the host computer 1 through the network 3 and allows facilities 5 to operate according to the processing conditions sent from the preprocess if the host computer is shut down. When the host computer 1 is normal, on the other hand, the facilities 5 are allowed to operate according to the processing condition data from the host computer. Consequently, even while the host computer 1 is at a stop, the processing is carried out.
