Abstract

PURPOSE: To give the display showing whether the program is progressed in the prescribed sequence, by memorizing the codes proper to the unit program into the status memory in the progress order of the program and at the same time displaying them.
CONSTITUTION: The program stored in memory 5 is divided into unit blocks 9W14, and the codes proper to each unit block, such as No.1WNo.6, are added. Then one step is provided within each unit block to give the command to memorize each code into status memory 8. As a result, the codes are memorized in sequence into memory 8 based on the program order. Thus the contents of memory 8 are read out in sequence, and the checking is given to the execution order of the program memorized in memory 8. In such way, the faulty area can be detected.
