Machine data acquisition control terminal system - manipulates instructions using hierarchical structure and permits dialogue with user

摘要

Collection and treatment of data from remote machines is accomplished by interrogation and response statements which are arranged in a hierarchical branching catalogue structure which can be programmed to suit diverse industrial systems. Data and the status of routines are displayed on a panel. A keyboard imploying dedicated sequence keys permits user-terminal interaction. Dialogue with the interrogation structure is governed by a manager unit which is linked by a bus to a micro-processor and memory unit which commission and store command routines. Command tables can be updated and supplemented from an alphanumeric keyboard.
