ABSTRACT:
A programmable controller which allows the operator to input a ladder symbol followed by device names separated by logical operators in lieu of entering the redundant ladder symbol for each device name. The logical operator is identified during the conversion into a ladder diagram display so that the program instruction will be properly interpreted and displayed. Commonly used ladder diagram segments may be stored in lo advance and subsequently inserted into the programmable controller program being written, after conversion of device names to suit the configuration for which a ladder program is presently being written.
