Abstract

Content is generated on a host system based on real-time data from a controlled process collected over an internet from a customer'"'"'s client machine tool control system. The real-time data is captured from the client machine tool by downloading software that manipulates controller functionality to perform a data capture trace predefined events and triggers. The captured data is retrieved by the host, which may generate content based on the data, or provide selective, authorized access to the data by others.
