Programmable controller

Abstract

Abstract PURPOSE:To attain simply the operation adding a comment to a prescribed location on a circuit diagram in a short time by reading a designated word from a dictionary memory by a prescribed key operation to constitute a comment sentence and storing it corresponding to the remarked location on the circuit diagram. CONSTITUTION:After an address of a comment memory 11 and a circuit element memory 9 is reset to zero in the programming processing at first, a key input data is read and the circuit element inputted by the key operation is transferred in a circuit diagram memory in a user program memory 5. Then the presence of the operation of a comment registration key is discriminated and when no operation of the comment registration key exists, after the address of the comment memory and the circuit element memory is stepped respectively and then the key input data is read again and the transfer of the circuit element onto the circuit diagram memory are repeated. Then the key operation is simplified remarkably by having only to designate the address of the dictionary.
