PURPOSE:To easily execute monitoring for an interlock instruction, by putting each different discriminating number to the interlock instruction in a user's program, and displaying it additionally. CONSTITUTION:To an interlock instruction in a user's program, each different discriminating number is added, and it is stored in a user's program memory 1. This discriminating number is held in an RAM6 until an interlock end instruction is executed. In this state, when a user's instruction placed between the interlock instruction and the interlock end instruction has become an object to be monitored, the discriminating number in the RAM6 is also transferred to a program console 7. This transferred discriminating number is additionally displayed on a ladder diaphragm on the console 7. These controls are executed by a CPU4. In this way, monitoring for the interlock instruction can be executed easily. |
