PURPOSE:To improve efficiency of an operator by storing data in a memory, informing it to the operator by a display lamp and calling it at an optional time when a message is received from the controller. CONSTITUTION:A message received through a transmission circuit 7 is read by a CPU 2 and stored in a data memory 6. At the same time, the CPU 2 sets a flip flop 8 in order to inform the receipt of the message to the operator and lights an indicator 9. By the lighting of the indicator 9, the operator presses a key switch for calling the message set in a keyboard input device 1. Then, the CPU 2 detects this, calls for the message recorded in the data memory 6 to set on a message display buffer 10 and displays the message on a message display device 11. The CPU 2, when the data to be displayed is present in the data memory 6, lights the message indicator 9 and when the data to be displayed is not present, lights off. |
