A programmable logic controller is a microprocessor used to control any electronically programmable device, such as a microwave oven, washing machine etc. and the Mitsubishi PLC is the most common in industry. The aim of this book is to provide the engineering technician with a sound working knowledge of PLC operation, with a minimum of unnecessary theoretical background. Content is determined by the needs of service engineers who encounter PLCs with increasing frequency in their work.
