Abstract: A control and program input arrangement for industrial process programmable controllers, and specifically for the controller microprocessor that provides manually operated mode operation and user programming controls that avoid the need for a coded terminal for user desired program entrying or modification, which arrangement comprises a control panel assembly including a master control panel section and associated status control panel sections, and manually operated keyboards associated therewith, that provide for manually effected shifting of the processor between tape reading, automatic operation, and manual operation modes, as well as for manual effectation of entry of programs into the programmable controller system memory at specific sites or slots of the memory map, checking of the accuracy of such entries, revision of such entries or previously made entries, and cancellation of same, without requiring use of the tape and tape reader components and associated parts of the system.
