<p>PURPOSE:To shorten a time used for confirming operation of self diagnosing by displaying the name and state of controlling signals on the same picture. CONSTITUTION:A PC main arithmetic section 81 is provided with an arithmetic main body section 81a that calculates control of the whole PC8, a judging section 81b that judges whether a diagnosis request flag designated by an input/ output section 12 is set to a common use memory 9 or not, a reading section 81c that reads an address from the common use memory 9 basing on the result of judgement of the judging section 81b and a comparing section 81d that judges whether the address read by the reading section 81c is the same with the content of last time or not. Basing on judgement of the comparing section 81d, only the status signal of a PC local memory 82 is set to the common use memory 9, or status signals of signal name data of a data memory 19 for display and the PC local memory 82 are set to the common use memory 9.</p> |
