PURPOSE:To shorten fault repair by monitoring the test flag of the arithmetic processing section, storing the contents of the I/O element when they are satisfied, and externally displaying them only when they are related to their energization and deenergization. CONSTITUTION:When the operator checks the sources for which the specified output relay is not actuated, he assigns the above output relay address on the output address setting device 21. On the other hand, the sequence controller mainframe sequentially tests the input signal based on the program stored in memory 10. When the conditions of the input signal are satisfied, it assigns the address in the address register 26. When the address output instruction assigned on the output address setting device 21 is read, the comparator 24 generates output and displays the contents of the address register 26. |
