21-59(10704)A PROCESS CONTROL TERMINAL Abstract of the Disclosure A process control terminal may be used in a computer network consisting of a process control network of process controllers and an application network of host computers. The process control terminal allows a process control operator access to both process control functions and application programs being executed by a host computer. The process control terminal includes an Ethernet controller and it emulates a standard DEC terminal in order to facilitate its use in preexisting computer systems. The process control terminal displays information relating to process control functions in a first portion of its associated CRT screen and information relating to applications programs in a second portion of the CRT screen, the second portion being exclusive of the first portion so that process control information is not overwritten by applications information. The process control terminal also includes an automatic login feature that allows an operator to automatically login to an application program without typing a username or a password.
