A method for synchronizing configuration data (111 - 222) of components (110, 120, 210, 220) within an industrial plant, the method comprising the steps of: partitioning a network in the industrial plant into a first sub-network and a second sub-network, said sub-networks (100, 200) connected by a network connection, wherein a first component (110, 120), comprising at least a first configuration data (111, 112, 121, 122), and a first local server are located in the first sub-network, and a second component (210, 220), comprising at least a second configuration data (211, 212, 221, 222), and a second local server are located in the second sub-network; storing the first configuration data (111, 112, 121, 122) on the first local server and, via the network connection, on the second local server, and storing the second configuration data (211, 212, 221, 222) on the second local server and, via the network connection, on the first local server; interrupting the network connection; updating, on the first local server, the first configuration data (111, 112, 121, 122) and the second configuration data (211, 212, 221, 222); re-connecting the network connection; if the first configuration data (111, 112, 121, 122) on the second local server is unchanged, overwriting the first configuration data (111, 112, 121, 122) on the second local server by the updated first configuration data (111, 112, 121, 122), and if the first configuration data (111, 112, 121, 122) on the second local server has been changed, overwriting the first configuration data (111, 112, 121, 122) on the second local server by the updated first configuration data (111, 112, 121, 122). partitioning a network in the industrial plant into a first sub-network and a second sub-network, said sub-networks (100, 200) connected by a network connection, wherein a first component (110, 120), comprising at least a first configuration data (111, 112, 121, 122), and a first local server are located in the first sub-network, and a second component (210, 220), comprising at least a second configuration data (211, 212, 221, 222), and a second local server are located in the second sub-network; a first component (110, 120), comprising at least a first configuration data (111, 112, 121, 122), and a first local server are located in the first sub-network, and a second component (210, 220), comprising at least a second configuration data (211, 212, 221, 222), and a second local server are located in the second sub-network; storing the first configuration data (111, 112, 121, 122) on the first local server and, via the network connection, on the second local server, and storing the second configuration data (211, 212, 221, 222) on the second local server and, via the network connection, on the first local server; interrupting the network connection; updating, on the first local server, the first configuration data (111, 112, 121, 122) and the second configuration data (211, 212, 221, 222); re-connecting the network connection; if the first configuration data (111, 112, 121, 122) on the second local server is unchanged, overwriting the first configuration data (111, 112, 121, 122) on the second local server by the updated first configuration data (111, 112, 121, 122), and if the first configuration data (111, 112, 121, 122) on the second local server has been changed, overwriting the first configuration data (111, 112, 121, 122) on the second local server by the updated first configuration data (111, 112, 121, 122).
