Abstract
A method and a corresponding device are disclosed for communicating between clients and servers of a client/server system using the standard protocol OPC UA, and for the interaction of an OPC UA client with an OPC UA server, OPC UA service calls are used. In order to integrate a transaction context in OPC UA service calls, all OPC UA servers of the system are complemented by a transaction management component, and in order to carry out transactions, appropriately configured OPC UA clients communicate with respective OPC UA servers using transactions.

A method for communication between a client and a server in a client/server system using an OPC UA protocol, comprising:
- making a OPC UA service call for interaction between an OPC UA client and an OPC UA server;
- and
- carrying out communications between the OPC UA client and the OPC UA server via transactions integrated in OPC UA service calls in a transaction context using a transaction management component, such that OPC UA clients trained to carry out transactions each communicate with an OPC UA server using transactions.
