Abstract
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.

A control system of a technical installation, comprising:
- a field device configured to provide two redundant protocol values, the two redundant protocol values being converted by the control system into a single non-redundant functional value;
- and
- at least two redundant communication channels for converting the two redundant protocol values into a single non-redundant functional value,
- wherein each communication channel controls one of the two redundant protocol values whether the redundant protocol value is correct, and
- wherein a correct redundant protocol value is being transmitted via the respective communication channel.
A method of operating a control system of a technical installation, comprising:
- providing two redundant protocol values by a field device;
- providing two redundant communication channels;
- controlling the two redundant protocol values whether the protocol values are correct, each communication channel controlling one redundant protocol value;
- transmitting correct redundant protocol values via the communication channels;
- and
- converting the correct redundant protocol values into a single non-redundant functional value.
