SYSTEM FOR TRANSPARENT MONITORING OF PROCESSORS IN A NETWORK WITH DISPLAY OF SCREEN IMAGES AT A REMOTE STATION FOR DIAGNOSIS BY TECHNICAL SUPPORT PERSONNEL

A remote diagnostic and monitoring system and method for use with an operation system having a multi-tasking interface to a real time control system, the remote diagnostic and monitoring system and method comprising a remote diagnostic task operating in an interface computer operatively connected to the operation system, a communication link, and a remote service computer coupled to the interface computer via the communication link. The remote diagnostic task operating on the interface computer can initiate and monitor from a remote location any of the procedures and controls run on the interface computer for controlling and monitoring the operation system. The remote diagnostic task receives instructions from a person at the remote service computer through the communications link and injects these instructions into the operating software of the operation system in a manner such that the remote source, i.e. the remote service computer, is indistinguisable from a local source. The remote diagnostic task is grouped or included with functionally partitioned application tasks in the interface computer and uses the multitasking operating system of the interface computer in the same manner as the application tasks.
