PLC BASED AUTMATION FOR FOOD INDUSTRY

Abstract

Recently the PLC (programmable logic controller) is essential part in any industrial systems and also some commercial systems. The PLC has high accuracy and fast response plus high performance, so it is suitable for industrial applications such as sensors signal, analogue input (thermal applications). Also the PLC took place in industrial circuits because the PLC contains a virtual relays, timers, and counters as software. All PLC types are compatible with HMI (human machine interface). PLC has many advantages for example it can upgrade to SCADA system (connecting with PC) to get good monitoring and find out any fault quickly, so it reduce the maintenance time. It is also suitable for hand free industry (food industry). `
