摘要

A method for optimizing repeated write access by a client to at least one variable in a server via OPC UA, wherein a call method for repeated write access is provided on the server, the call method includes notification of an access time interval and at least one variable for the repeated write access, the client calls the call method on the server, the server is notified of an access time interval and the at least one variable for the repeated write access in the process, where the server creates a data structure for the repeated write access and maintains said data structure during the access time interval, values of the at least one variable which are to be written are transmitted to the server by the client during the access time interval, and the server allocates each value transmitted by the client to the associated variable.
