And a designation information storage unit for storing designation information for designating a communication protocol to be connected to the control unit via a line. When the power is turned on, the designation information stored in the designation information storage unit is designated. Based on the information, a line is connected to the control unit.

According to a second aspect of the present invention, there is provided a teaching box which supports a control unit for controlling a controlled device by a unique communication protocol using a communication protocol of the control unit, wherein the teaching box is connected to the control unit via a line. A designation information storage unit for storing designation information for designating a communication protocol to be performed, and when the power is turned on, the designation information stored in the designation information storage unit is used for line connection with the control unit. Specifying information determining means for determining whether or not the information is specified information, and the specified information determining means determines whether the specified information stored in the specified information storing means is not for line connection with the control unit. Comprises designation information registering means for registering new designation information in said storage means.

The invention described in claim 3 is the first or second invention.

The communication control parameter data 20a includes a frame configuration field 20ac and a command transmission / reception content field 20ad having command transmission / reception content at the time of initial connection.

Incidentally, the communication control parameter data 20a marked with “A” indicates that the connection model is “model 2”, the communication speed is “4800 bps”, the communication frame is 8 bits as data bits, and 1 bit as stop bits. And one bit as the parity bit, and the command transmission / reception content at the beginning of the connection is such that the model confirmation command is received from the connected model.

The EEPROM 13 has a ROM
Communication control parameter data 20a stored in
Is set, the connection model name in the set communication control parameter data 20a is stored.

The RAM 14 temporarily stores data read from the EEPROM 13.

Next, the operation of the teaching box of this embodiment will be described with reference to the flowchart of FIG.

When the user turns on the power of the teaching box (step 110), the CPU 11 determines whether or not the [clear] key has been pressed (step 12).
0).

When the CPU 11 determines that the [Clear] key has been pressed (step 120; Y), it reads the connected model name input by the user (step 13).
0).

Then, the CPU 11 determines whether or not the read connection model name corresponds to any of the connection model names of “model 1”, “model 2”, “model 3” and “model 4”. (Step 140).

Thereafter, the CPU 11 registers the connected model name input by the user in the EEPROM 13 (step 150), and proceeds to step 170.

In step 120, the CPU 11
If it is determined that the [Clear] key has not been pressed (step 120; N), the connected model name registered in the EEPROM 13 is read and stored in the RAM 14 (step 160).

Thereafter, the CPU 11 determines whether or not the connection model name stored in the RAM 14 is "model 1" (step 170). As a result, if it is determined that the connection model name is "model 1" (Step 170; Y), it waits for an LED lighting request command from the control unit 20 (Step 180).

Subsequently, the CPU 11 determines whether or not a model confirmation command has been received within three seconds after the power is turned on (step 190). Is (Step 190; N),
The process proceeds to step 130 and performs the same processing as described above.

On the other hand, if the CPU 11 determines that the model confirmation command has been received within 3 seconds (step 19).
0; Y), it is recognized that the line connection with the control unit 20 has been established (step 200), and the line connection processing ends.

In step 170, the CPU 11
If it is determined that it is not “model 1” (step 17
0; N) Next, it is determined whether or not the connected model name stored in the RAM 14 is “model 2” (step 21).
0).

If the CPU 11 determines that the type is "model 2" (step 210; Y), it waits for a model confirmation command from the control unit 20 (step 22).
0).

Subsequently, the CPU 11 determines whether or not a model confirmation command has been received within 3 seconds after the power is turned on (step 230). Is (Step 230; N),
The process proceeds to step 130 and performs the same processing as described above.

On the other hand, if the CPU 11 determines that the model confirmation command has been received within 3 seconds (step 23).
0; Y), it is recognized that the line connection with the control unit 20 has been established (step 240), and the line connection processing ends.

In step 210, the CPU 11
If it is determined that it is not “model 2” (step 21
0; N) Next, it is determined whether or not the connected model name stored in the RAM 14 is “model 3” (step 25).
0).

If the CPU 11 determines that the type is "model 3" (step 250; Y), the CPU 11 waits for a model confirmation command from the control unit 20 (step 26).
0).

Subsequently, the CPU 11 determines whether or not a model confirmation command has been received within 3 seconds after the power is turned on (step 270). Is (Step 270; N),
The process proceeds to step 130 and performs the same processing as described above.

On the other hand, if the CPU 11 determines that the model confirmation command has been received within three seconds (step 27).
0; Y), it is recognized that the line connection with the control unit 20 has been established (step 280), and the line connection processing ends.

At step 250, the CPU 11
If it is determined that it is not “model 3” (step 25
0; Y), and it is determined whether or not the connected model name stored in the RAM 14 is “model 4” (step 29).
0).

If the CPU 11 determines that the type is "model 4" (step 290; Y), it outputs an initial data read command to the control unit 20 (step 300).

Subsequently, the CPU 11 determines whether or not there has been any response from the control unit 20 within 3 seconds after the power is turned on (step 310). Step 310; N), and proceed to Step 130 to perform the same processing as described above.

On the other hand, if the CPU 11 determines that any response has been received within 3 seconds (step 3
10; Y), it is recognized that the line connection with the control unit 20 has been established (step 320), and the line connection processing ends.

In the teaching box of this embodiment, the EEPROM 13 stores a model name for designating a communication protocol to be connected to the control unit 20 via a line.
When the power is turned on, a line can be connected to the control unit 20 based on the model name stored in the EEPROM 13.

Therefore, the useless operation of setting the model name, which has been performed every time the power is turned on, can be omitted, and the operability can be improved.

[0041]

As described above, according to the present invention, the designated information storage means stores designated information (model name) for designating a communication protocol to be connected to the control unit via a line, and is stored when the power is turned on. Since the line can be connected to the control unit based on the specified information, the useless operation of setting the specified information every time when the power is turned on can be omitted, and the operability can be improved. There is an effect that can be.
