An apparatus control method used to control a field data processing apparatus on an industrial site, where the method comprises: receiving, by a server located in a central position of said industrial system, a field data acquisition permission request (AUC REQ) message from said field data processing apparatus, wherein said field data acquisition permission request message comprises an identification of said field data processing apparatus and is used for said field data processing apparatus to request the right to acquire field data from at least a field apparatus on said industrial site; determining, by said server, whether said field data processing apparatus has the right to acquire said field data; receiving, by said field data processing apparatus, a data acquisition permission acknowledgement (AUC RSP) message from said server if said field data processing apparatus has the right to acquire said field data, in response to said permission request message and determination that the field data processing apparatus has the right to acquire field data, sending, by said server, a notification message (INF MSG2) to a field control apparatus wherein said notification message (INF MSG2) is used to notify said field control apparatus that said field data processing apparatus with said identification has the right to acquire said field data, and wherein the field control apparatus is configured to collect said field data; sending, by the field data processing apparatus, a field data acquisition message request (DATA REQ2) message to the field control apparatus, wherein the field data acquisition message request (DATA REQ2) message comprises the identification of the field data processing apparatus, sending, by the field control apparatus and after the field control apparatus determines that said field data processing apparatus has the right to acquire said field data based on said identification, field data of said at least a field apparatus to the field data processing apparatus, wherein the field data processing apparatus is used to process field data on the industrial site and provide the processing result on the industrial site. receiving, by a server located in a central position of said industrial system, a field data acquisition permission request (AUC REQ) message from said field data processing apparatus, wherein said field data acquisition permission request message comprises an identification of said field data processing apparatus and is used for said field data processing apparatus to request the right to acquire field data from at least a field apparatus on said industrial site; determining, by said server, whether said field data processing apparatus has the right to acquire said field data; receiving, by said field data processing apparatus, a data acquisition permission acknowledgement (AUC RSP) message from said server if said field data processing apparatus has the right to acquire said field data, in response to said permission request message and determination that the field data processing apparatus has the right to acquire field data, sending, by said server, a notification message (INF MSG2) to a field control apparatus wherein said notification message (INF MSG2) is used to notify said field control apparatus that said field data processing apparatus with said identification has the right to acquire said field data, and wherein the field control apparatus is configured to collect said field data; sending, by the field data processing apparatus, a field data acquisition message request (DATA REQ2) message to the field control apparatus, wherein the field data acquisition message request (DATA REQ2) message comprises the identification of the field data processing apparatus, sending, by the field control apparatus and after the field control apparatus determines that said field data processing apparatus has the right to acquire said field data based on said identification, field data of said at least a field apparatus to the field data processing apparatus, wherein the field data processing apparatus is used to process field data on the industrial site and provide the processing result on the industrial site.
