Recent Developments on PC+PLC based Control Systems for Beer Brewery Process Automation Applications

Manufacturers are continuing to do their best efforts for cost effective production systems in order to contribute consumers' requirement. Such environment carries plant operations using quite flexible control systems such as PC (personal computer) - PLC (programmable logic controller) combination control systems called PC+PLC based control system. However, almost PC+PLC based control systems has been applied for small to medium scale processes which have the hundreds I/O points or less. We have jointly developed the new large-scale application systems in applying PC+PLC based control systems for beer brewing plants. Through those projects we come to the practical and effective PC+PLC based control systems' application for quite large-scale processes with enough production performance and flexible operations
