DEVICE CONTROL SYSTEM FOR PRODUCTION LINE

PURPOSE:To control the devices at a high speed and with high accuracy by providing a priority storage means, a control processing sequence storage means, a device control means, and an instruction information sequence control means. CONSTITUTION:The information including the priority of various devices 1 are stored in a storage means 2 and the address instruction information on each device information on the means 2 is stored in a storage means 3. A device control means 4 refers to the head instruction information on the means 3 to read the device information out the means 2 and to control the corresponding device and at the same time rewrites the priority of the device information with end of the control of the relevant device. Then an information sequence control means 5 rearranges the instruction information on the means 3 based on the priority of the device information rewritten by the means 4 as well as the priority of other device information. Thus the means 4 refers to the head instruction information on the means 3 to read the information device on the means 2 and refers to the device information to be controlled next. As a result, the device to be controlled next is retrieved at a high speed regardless of the type the device.
