Einsatz einer fehlersicheren SPS bei der Modernisierung eines Aluminium -Schmelzofens

Programmable logic control systems are a rational augmentation of the potentials of electronic control and instrumentation arrangements. Complex safety-orientated and control functions can be cost-effectively and reliably combined in a single PLC installation, without impairing operability and flexibility, via the addition of a number of individual components of a standard PLC system. The following article describes the practical use of error-proof control in twelve aluminium melting furnaces at TRIMET ALUMINIUM AG, Essen. Ger-many, in the context of modernization of the heating system, examining the benefits and disadvantages resulting from installation.
