Abstract

PURPOSE:To reduce remarkably the number of signal lines by sending out a discriminating code, and thereafter, transferring successively a binary code of 4-bit for displaying the contents of decimal each digit of a data, in parallel at every decimal each digit. CONSTITUTION:With regard to a data of a control parameter, etc., for instance, in case when a decimal number of 6789 is transferred, first of all, a discriminating code for making an object to be controlled discriminate what the data is sent out together with a strobe signal. Subsequently, a binary code of six for displaying the contents of 1,000 digits is sent out together with a strobe signal. Thereafter, a binary code of seven for displaying the contents of 100 digits is sent out together with a strobe signal. In the same way, a binary code for displaying the contents of a digit of ten and a digit of one is transferred successively together with a strobe signal. A microprocessor of a controlled system OBJ selects a corresponding output port by discriminating code, also executes a series/parallel conversion to decimal each digit from a controlling circuit CONT, restores it to a decimal number, and outputs it to a selected output port.

響を及ぼすという問題があった。Conventional technology and problems Conventionally, when transferring data expressed in BCD codes such as control parameters and auxiliary function codes from an NC control circuit to a controlled object, the data was expressed in decimal notation (1) Dedicated signals were used for each type of data. A line was provided, and all of this data was transferred in parallel, and a binary code indicating the content of each decimal digit was transferred in parallel for each decimal digit. Therefore, for example, to transfer 10 types of data displayed in a 4-digit decimal BCD code, 4 (bits) x 4 (digits) XIO (types) - 160 parallel transfer signal lines are required. However, the total number of signal lines becomes enormous, which not only makes wiring between devices complicated and expensive, but also adversely affects the reliability of the system.
