There was something that turned on and off the indicator lamp. However, this system requires as many electric wires as the number of display lamps plus one, including the common line, and there is a problem in that the more the number of display lamps increases, the more complicated the wiring becomes.

For this reason, two-wire systems have also been devised and provided. This system consists of three parts: a transmitter, a receiver, and a reference pulse generator.The reference pulse generator generates a reference pulse to synchronize the operations of the receiver and transmitter. The address was sent to each address via a transmitting/receiving line to synchronize the address sending registers provided in each transmitting/receiving section.

Then, a command area is provided between these reference pulses, and when an operation such as going to work or leaving work is performed, a corresponding signal is sent from the transmitter on the same transmission/reception M line as the reference pulse, and is combined with the reference pulse on the transmission/reception line to generate a series of signals. Create a pulse train I10 signal,
On the other hand, the receiving section determines the presence or absence of signals in two command areas for each reference pulse, detects which command area of which pulse, and controls the display section provided in the receiving section. It had become.

Therefore, the relationship between the display section and the personal name assigned in correspondence with the display section must be set in advance for each system, which poses a problem in that it is difficult to increase the number of systems.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and its purpose is to improve the relationship between the display section provided on each desktop operating device and the personal name assigned to each display section.

8, when the writing to the memory 16 is completed, the operation mode is set to the normal operation mode by the selection switch SW, the system is started, and the controller 1 communicates with the transmission calculation control means 15a of the transmission unit 15 for transmission and reception. The start signal ST, address data signal AD, control data signal CD, parity check CH, and return signal *m shown in FIG. 9 are converted into a predetermined signal format by the circuit 15b.
A transmission signal consisting of a period RD is cyclically transmitted sequentially along the addresses by time division multiplexing.

When a desk operating device 3a, for example, the operating section 8 corresponding to the display section 7 whose name number is 1, is operated, the desk operating device 3a transmits a return signal of the transmission signal by the operation of the transmission control means 10. During the waiting period RD, a wi') included signal is sent as a return signal. This interrupt signal is sent back to controller 1 via transmission #12. In the transmitter 15 of the controller 1, the received return signal is received and reproduced by the transmitting/receiving circuit 15b, and further converted into a signal that can be transferred to the arithmetic control means 20 by the transmission arithmetic control means 15a and sent to the arithmetic control means 20. When the arithmetic control means 20 determines that it is an interrupt signal, it sets it to interrupt mode, causes the transmission section 15 to send out a signal requesting return of address data, and among the tabletop controllers that have received this signal, interrupts the tabletop controller. 3a returns the address data of the rental operation device 3a. Upon receiving this return signal, the controller 1 uses the arithmetic control means 20 to determine the address that requested the interrupt, and sends out a transmission signal to call the tabletop controller 3a at the address. Then, during the return period ff-iso period RD of the transmission signal, the operation data of the tabletop operation device 3a is sent out. When the returned operation data is received and read by the arithmetic control means 20, the interrupt mode is canceled and the controller 1 returns to normal operation. And the display NS7 with the same name number as the display @7 corresponding to the operated operation 8BB
Display device 4a, 4b or tabletop operation device 3 with
The controller 1 transmits a control data signal for controlling the display unit 7 when accessing the display unit 7a, 3b, and 3c based on the data in the memory 16. If the display mode is set to 2 mode, for example, the red light emitting diode L2 is turned on or off. This control state is performed by reversing the previous state, and is reversed every time the corresponding operation section 8 is operated. In the case of 4 modes, each operation of the corresponding operation unit 8 causes only the green light-emitting diode L to light up, only the red light-emitting diode L to light up, and all the light-emitting diodes L to light up.
, L2 are turned on, all the light emitting diodes L, , L2 are turned off, and the control data is created so that a display of green, red, yellow, and turned off is obtained. Here, you can assign appropriate meanings to each of them, such as going to work when the light is green, being in a meeting when it is red, being on a business trip when it is yellow, and leaving the office when the light is off. I understand. Of course, the operator only has to operate the operating section 8 until the emitted light color becomes a predetermined color.

The display section 7 set to the name number corresponding to the operating section 8 operated in this way is the desktop operating device 3a, 3b, 3C.
The display devices 4a and 4b are controlled to the same state. This operating state corresponds to the corresponding operating section 8.
will be maintained until the control data sent from the controller 1 changes.

When checking the contents of memo 916, press the selection switch SW.
Set the read mode with
If you operate , the number on the display section 7 corresponding to the predetermined name number or the tabletop operation device 3 at 3 b.

3c and the addresses on the displays 4a and 4b can be confirmed.

Incidentally, the display units 4a and 4bl: The display unit 7 provided is one that can display four modes by light emission from the light emitting diodes L, L2, but it is also possible to display inverted display using an incandescent lamp or the magnetic driving force of a set of shutters. When using a device, etc., only the tlY light and 5α light patterns can be displayed,
When a 4-mode display is set, the following four types can be selected for the on/off state using the setting switch SW2.

That is, one mode is on for green and off otherwise, one mode is on for green and red and off otherwise, and the other is on for green and yellow and off otherwise. There are four lighting modes to choose from: green, red, and yellow.
