PURPOSE:To reduce malfunctions of a device to be controlled by providing a sequence controller with device control numbers and a file with file data numbers and by reproducing data of the file when the both agree with each other on the controller. CONSTITUTION:When a signal for reproducing data of file 1 in memory part 3 of the sequence controller is generated by file operating device 2, file data numbers registered in file 1 are detected by file data number detector 4. The detected file numbers are compared by coincidence detecting circuit 6 with device control numbers 5 stored in the dedicated memory of file operating device 2 and only when the both agree with each other, a coincidence signal is sent to gate 7, which opens to reproduce the data of field 1 in memory part 3 of the sequence controller. |
