The process needs to log in the MN master station node (each master station of multi-master redundancy or each master station of a multi-set master-slave system) one by one for operation, and due to the complexity of an industrial field, phenomena such as operation omission, operation errors and the like easily occur in the updating process, so that a plurality of inconveniences are brought to the maintenance of Ethernet Powerlink master station equipment manufacturers and the use of clients.
