Abstract
A batching system for operating each cycle of a batching process includes a communications bus to which are connected a basic processor, a control console, an analog/digital converter module, and an interface unit. The basic processor includes RAM memory means, PROM memory means and a central processing unit containing a microprocessor. The control console includes display means, a group of set-up pushbutton switch means, a group of operate pushbutton switch means, keyboard means having a number of pushbutton switch means each providing a different BCD signal, and switch means to activate alternatively the group of set-up pushbutton switch means or the group of operate pushbutton switch means. When the set-up pushbutton switch means are activated, the pressing of each button activates a different mode of the PROM memory means. By operating these switch means followed by operation of one or more buttons of the keyboard changes can be made in the digital information stored in the RAM memory means. Information stored in the RAM memory means relevant to a pushbutton is displayed on the console and changed when the keyboard is operated.
