A control system of a technical installation including at least one field device which makes available at least two redundant protocol values that are converted by the control system into a single non-redundant functional value is provided. The control system is provided with at least two redundant communication channels for converting the at least two redundant protocol values, the channels controlling the respective protocol value with respect to its exactitude and transmitting an exact protocol value.

In a client/server computer architecture, a message signal appearing on a server computer is assigned a further message signal and the latter is written to a pipe and transmitted to a servlet on the server computer via the pipe. The further message signal is then transferred to a client computer via a transfer channel by way of the servlet. Here, the message signal is decoupled from the corresponding further message signal, with the fate of the message signal after it has appeared no longer directly influencing the fate of the associated message signal.
