【Example】

Embodiment 1 FIG. First, the configuration of a signal transmission system using the first embodiment of the present invention will be described with reference to FIG. FIG.
FIG. 1 is a block diagram showing a signal transmission system using the first embodiment of the present invention. A controller 1, a transmission line 2, and a terminal device 5 are exactly the same as those of the above-described conventional system. In the drawings, the same reference numerals indicate the same or corresponding parts.

Next, the configuration of the first embodiment of the present invention is shown in FIG.
This will be described with reference to FIG. FIG. 2 shows Embodiment 1 of the present invention.
FIG. 3 is a block diagram showing a circuit configuration of FIG.

In FIG. 2, reference numerals 10, 11, 12, and 13 denote eight operation switches 6 (SW1 to SW8, SW
9 to SW16, SW17 to SW24, SW25 to SW3
2) is connected and buffers for reading the input state of the operation switch 6, and each of 14, 15, 16, and 17 has eight LEs.
D (LED1-LED8, LED9-LED16, LE
D17 to LED24, LED25 to LED32) are connected, and are flip-flops for turning on, off, and blinking the LEDs.

The display LED 7 is connected to buffers 10 to 13 and flip-flops 14 to 17,
And a three-state buffer 19 for switching the input / output direction of the operation switch 6 and the like.
A decoder connected to the N terminal to select the operation switch 6 in units of 8 bits, a decoder 20 connected to the CK terminals of the flip-flops 14 to 17 and selecting an LED in units of 8 bits, 21 a 3-state buffer 18, a decoder 1
CPUs connected to 9, 20; 22, a mode switch connected to the CPU 21; 23, a ROM;
25 is a transmitting / receiving circuit.

The display lamp according to the present invention corresponds to an LED in the first embodiment of the present invention, and the control means according to the first embodiment includes buffers 10 to 13 and flip-flops 14 to 17 in three states. Buffer 18, decoders 19 and 20, CPU 21, ROM 23, and RA
M24.

Next, the operation of the first embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing the operation of the first embodiment of the present invention. In step 30, the CPU 21 reads the mode switch 22.

In step 31, it is determined whether or not a message has been received from the controller 1 (master station) via the transmission line 2. If not, the process returns to step 30, and if so, the process proceeds to the next step 32.

At step 32, it is determined whether or not the received message is a "display lamp lighting" command.

In steps 33 to 35, if the mode selected by the mode switch 22 is the remote control switch mode, the ON / OFF data is converted from rows (for annunciators) to columns (for remote controls). Then, the display lamp 7 (LED) is turned on / off, and the process returns to step 30.

In step 36, it is determined whether the received message is a "switch monitor" command. If not, the process returns to step 30.

In steps 37 to 39, if the mode selected by the mode switch 22 is the remote control switch mode, the switch read data from the operation switch 6 is converted from a row (for an annunciator) to a column (for a remote control switch). . Then, the switch read data is returned to the controller 1 via the transmission line 2, and the process returns to step S30.

A specific example will be described with reference to FIGS. FIGS. 4 and 5 are front views of the first embodiment of the present invention.

In the annunciator 3A, operation switches SW1 to SW32 and display lamps LED1 to LED32 are arranged on the hardware as shown in FIG. That is, it is the same as the arrangement of the operation switches 6 and the LEDs 7 in the remote control switch shown in FIG.

Operation switches SW1 to SW32 and display lamps LED1 to LED in the annunciator mode
The arrangement of 32 is as shown in FIG. For example, when LED 9 is selected by a command from the controller 1,
In the remote control switch mode, the hatched portion in the first row and the third column shown in FIG. 4 is used. In the annunciator mode, the second line shown in FIG.
The LED in the hatched portion of the row and the first column is turned on.

That is, in the remote control switch mode,
The CPU 21 stores the 8-bit “1” in the 3-state buffer 18.
00000000 ”and two bits“ 01 ”are set to the decoder 20 through the input terminals A1 and A0.In the annunciator mode, eight bits“ 01000000 ”is stored in the three-state buffer 18 and two bits are stored in the decoder 20. Of the operation switch SW1 in the three-state buffer 18.
SW32 and data for selecting the LEDs 1 to 32, and the decoders 19 and 20 are set with data for selecting the buffers 10 to 13 and the flip-flops 14 to 17.

Further, the lowermost portion at the left end (fourth row, first column)
When the operation switch 6 is pressed, the controller 1 is informed that the switch 4 has been pressed in the remote control switch mode and that the switch 25 has been pressed in the annunciator mode.

Embodiment 1 of the present invention, as described above,
A mode switch 22 is provided on the back surface, the mode is read by the CPU 21, and an ON / OFF command from the controller 1 is converted from a row to a column or from a column to a row according to the mode to drive the LED. Also, the operation switch 7 is turned on.
Since the / OFF state has a function of converting the row to the column or the column to the row and communicating with the controller 1, the annunciator 3A can be used in the same sense as a remote control switch, and a single annunciator and a normal annunciator can be used. There is an effect that the function of the switch can be performed.
