The fuel of Industry 4.0 is called data. It’s about using data to improve business and production processes. On the shop floor, data can be generated in parallel with production processes. State-of-the-art software can then be used to analyze the data and gain extensive insights from it. The problem, however, is the diversity of today’s existing assets. 60% of all industrial companies state in the Industry 4.0 study by McKinsey that around 30% of existing machines will have to be replaced for this. Not all machines are designed for digitization and can collect data by default. These machines create blind spots on the shop floor. To solve this problem, one could think of replacing the existing equipment with newer, digitized equipment. However, this is a costly approach that comes at the expense of cash flow. A more sensible approach, on the other hand, is “retrofitting”, i.e. upgrading old analog existing equipment to equipment that can capture and process data. FORCAM offers a number of methods for this approach to connect all machines. These methods even make it possible to integrate machines of any construction age.
