PURPOSE:To facilitate monitoring regarding an interlock instruction, by adding discrimination numbers individually to an interlock instruction in a user program, and monitoring and displaying the number of the interlock instruction to be monitored. CONSTITUTION:When an interlock flag F2 is set to ''1'', i.e. in an output inhibition state, an interlock discrimination number (IL number) stored in a register R0 is displayed in addition to an address, instruction, and contents of flags F0 and F1 to be monitored. A user inputs the code key of an interlock instruction and the displayed IL numbers to generate a retrieval command. Then, when the interlock instruction of some IL number specified to be monitored during the execution of a user program is executed by a CPU4, monitor data on the interlock instruction is displayed to find the address of the interlock instruction. |
