CAMAC Software for the Hot Fuel Examination Facility Real-Time Computer System

Software based on the CAMAC standards has been developed for a real-time data acquisition and process control system. The system is used to control the examination of irradiated fuel elements. Employing CAMAC in software has resulted in the development of a standard method of addressing the acquisition and control hardware. A description of a subroutine that outputs command words to the CAMAC system, checks for transmission errors, and checks for completion of the CAMAC handshake is presented. Use of this subroutine decreases programming time and training time due to system expansion or changes. Modularization of software through the use of subroutines has simplified programming of the software system.
