Abstract :
The use of standard industrial programmable controllers in safety critical applications is considered. Various configurations are described and the advantages and disadvantages of each considered. The use of independent machines and asynchronous processing are discussed. The role of serial communications in each configuration is explained and the benefits considered. Various issues of quality assurance and failure rate analysis are addressed. A number of practical applications are also briefly described
