ABSTRACT:
A microprocessor based single loop control instrument is described which can operate as any one of several different types of controllers, each of which can provide two or more different modes of operation. The control instrument comprises a microprocessor, a read only memory in which is stored the operating program for the control instrument, means for causing the control instrument to operate as one of the types of controllers provided for by a program stored in the read only memory and means for selecting the mode of operation of the controller. Further, in accordance with the invention, the control instrument is supplied with a control panel controlled by a second microprocessor and connected to the first microprocessor by a communication bus. The second microprocessor controls a bar graph display for displaying at least one signal related to the operation of the control instrument as well as means for selecting the signal that is displayed. Advantageously, the control panel also mounts switch means for selecting the mode of operation of the controller. Also in accordance with the invention, the control instrument can be configured by a keyboard/display which permits the selection of numerous processing options in the execution of the control algorithm.
