Abstract:
1. A vacuum processing apparatus comprising: a transfer module that transfers an object to be processed; a transfer module control device that repeatedly acquires state data of the transfer module at first intervals and stores the acquired state data of the transfer module therein; a process module that is connected to the transfer module and performs processing on the object to be processed which is transferred from the transfer module; a process module control device that repeatedly acquires state data of the process module at second intervals and stores the acquired state data of the process module therein; and a data collection device that collects the state data of the transfer module and the state data of the process module, wherein the transfer module control device, the process module control device and the data collection device are connected in a loop and are configured such that a state data set including the state data of the transfer module and the state data of the process module can be transmitted and received between each other, wherein the data collection device is configured to receive the state data set from one of the transfer module control device and the process module control device and transmit the received state data set to the other one of the transfer module control device and the process module control device, and where the other one of the transfer module control device and the process module control device is configured to receive the state data set from the data collection device to replace, in response to timing of reception of the state data set, only its own state data portion in the received state data set with the latest state data stored therein to create an updated state data set including the latest state data and the state data of the one of the transfer module control device and the process module control device in the received state data set as it is, and to transmit the updated state data set to the one of the transfer module control device and the process module control device.
