Abstract

A connection unit, also referred to herein as Quick Connect Box (QCB), is installed on each industrial machine to be monitored in a production plant. Each connection unit is “coded” to correspond to the particular production machine to which it is installed. The code may be binary or a certain sequence of digital alphanumeric characters, a certain pattern of analog voltages at certain locations in the QCB unit'"'"'s electronic circuits, or other means. The code or the signal pattern may identify the significant attributes of the machine being monitored, such as the machine name and type, plant name, asset number, the department and physical location within the plant, the operation number, and the types of sensors mounted on the machine and their set ranges.
