Introduction
The 20th century was the period that companies built the rich lives through the mass production, bulk consumption and destruction. The 21st century is the period that the environment and industrial revolution live together with our conscious of environmental problem caused from those results. This is the word our president says, A thing left in industry society . That means we hold many negative inheritances such as the problems of environment, resources, energy, industrial wastes, foods, population, logic and human rights, though the industry provided us rich lives. The environmental problems we have now, such as warming and environmental pollution caused by chemical matters is the global subjects. And it s not necessary to say each company should actively try to solve these problems. However, from the view of company level, unfortunately we should say the priority of the investment for system facility improvement is still low because bearing facility investment cost is high. This matter is largely affected by the countermeasure done in the nation level. In this series, we introduce the process how the users grappling with environmental problem from the company moral selected PBPC. Those users are playing the active parts in new business related to environmental problems. For series 1, we consider the basic features and effects of PBPC on the base of user application.After series 2, we focus on the future direction of PLC process control by introducing user applications. In the articles, we also introduce our view and subjects through the discussion with users.
