PREPARING DEVICE AND TRANSLATING DEVICE FOR CIRCUIT DIAGRAM

摘要

PURPOSE: To give a circuit description of high readability for gathering information for monitoring start conditions, operation conditions, etc., into a memory of one word with a small-scale circuit diagram for a programmable controller use circuit diagram. CONSTITUTION: It is made possible to describe a word memory allocation symbol A in a specific column in the output condition part (e) of an output description line 100. The symbol 'A' is a symbol indicating that a signal of an input description line or an arithmetic result is written at the bit position specified with the word memory bit position symbol (hexadecimal value) described in the same column with the symbol 'A'. Further, it is made possible to describe an emphasized display symbol 'F' in a specific column in the output condition part (e) of the output description line 100. This symbol 'F' is a symbol indicating that the word memory bit symbol (hexadecimal value) described in the same column with the symbol 'F' is emphasized and displayed according to the contents of a memory corresponding to the output description line where the symbol 'F' is described.
