Abstract

In A, switch panel 10 is part of a multimode console of a data processing system. Operator selection of one of the select switches I to IV located in the panel 11 initiates a predetermined program, i.e., software, in the data processor, not shown. The data processor in turn provides control signals which illuminate one or more of the function display indicators 12, representing the particular function(s) to be or capable of being performed by the computer under the control of the selected program. As the program is being run in the computer, the data processor also provides control signals which control one or more of the status display indicators 13, each of which is associated with one of the illuminated function display indicators 12 as the particular function or functions are being performed.

Switch Panel System With Built In Test

In A, switch panel 10 is part of a multimode console of a data processing system. Operator selection of one of the select switches I to IV located in the panel 11 initiates a predetermined program, i.e., software, in the data processor, not shown. The data processor in turn provides control signals which illuminate one or more of the function display indicators 12, representing the particular function(s) to be or capable of being performed by the computer under the control of the selected program. As the program is being run in the computer, the data processor also provides control signals which control one or more of the status display indicators 13, each of which is associated with one of the illuminated function display indicators 12 as the particular function or functions are being performed. Thus, for example, as shown in A, both display indicators 12 and 13 of each of the associated indicator pairs 21 and 24 of the upper bank and of the pair 28 of the lower bank are illuminated, as illustrated by the unshaded areas thereof. Thus, pairs 21, 24, 28 indicate that the functions which they represent are currently being carried out by the computer. On the other hand, for pairs 23 and 26, only the function indicators 12 are illuminated, but their respective status indicators 13 are not, as illustrated by the shaded areas. In this case, pairs 23 and 26 represent that their functions are not currently being performed in the computer. Similarly, none of the pairs 22, 25 and 27 is illuminated thereby representing that their particular functions will not be performed by the selected program.

Each of the indicator pairs is also associated with a pushbutton switch 31 which, when actuated by the operator, allows one or more of the functions of the selected program to be performed by the CPU on a priority basis in lieu of or concurrently with the other function(s) the CPU may be performing at the time. The block diagram of B illustrates the built-in test system for one of the indicator pairs of the panel 10. By way of example, each selected program includes a diagnostic test routine which causes the central processing unit CPU 14 to generate test signals for periodically testing the condition of the illuminators, shown as light emitting diodes (LEDs) 12' and 13' of each indicator pair. The test signals are fed via an appropriate 1/0 device 15 t...
